When air is supplied to all ports afterthe solenoid valve is in a pressure-center position, thepistons for rotary operation do not have any thrust, asthe pressure on both sides is equal, and the pistons forrotary operation move to the centre position due to thethrust of the pistons for centre stop. When all of thepistons (centre stop and rotary operation) are in contactwith each other, the piston system stops.Piston for centre stopExhaustSupplySupplyEnd of counterclockwise directionPiston for rotary operationCentre positionSupplySupplyEnd of clockwise directionExhaustA load can be mounted directly on the table.A High-precision model is also available in addition to the basic model.Basic model: MSZBHigh-precision model: MSZARolling bearingHigh-precisionbearingModelSizeTorque (N·m)Port sizeBasicMSZBHigh-precisionMSZA102030501235M5Features 1

Rotary TableAir ConsumptionAir consumption is the volume of air which is expended by the rotary actuator’s reciprocal operation insidethe actuator and in the piping between the actuator and the switching valve, etc. This is necessary forselection of a compressor and for calculation of its running cost.QCR = V xP+0.10.1x 10 –3 ···(1)PQCP = a x l x0.1x 10 –6···(2)QCR = Amount of air consumption of rotary actuator[l (ANR)]QCP = Amount of air consumption of tube or piping[l (ANR)]V = Inner volume of the rotary table [cm 3 ]P = Operating pressure[MPa]l = Length of piping[mm]a = Inner sectional area of piping [mm 2 ]To select a compressor, it is important to select one that hasplenty of margin to accommodate the total air volume that isconsumed by the pneumatic actuators that are locateddownstream. The total air consumption volume is affected by theleakage in the tube, the consumption in the drain valves and pilotvalves, as well as by the reduction in air volume due to reducedtemperature.FormulaQc2 = Qc x n x No. of actuators x Margin rateQc2 = Amount of exhaust air from a compressorn = Actuator oscillations per minute[l /min (ANR)]Internal Cross Section of Tubing and Steel PipingInternal volume changes depending on the rotating direction(refer to the figure shown in the lower right). Because of this, toobtain the total air consumption, first calculate the airconsumption of each stroke respectively by using formula (1),then add up each result.Air in the tubing is only consumed when the table rotates fromend to centre. The air consumption in the tubing can be obtainedby using formula (2).The internal volume for each rotating direction and the airconsumption at each operating pressure calculated using formula(1) are shown in the table below.NominalT0425T0604TU 0805T08061/8BT1075TU 1208T12091/4BTS 16123/8BT16131/2B3/4B1B[Calculation example]Size: 10 Operating pressure: 0.5 MPa Inner sectional area of piping: 12.6 mm 2Lengh of piping: 1000mm Stroke: Centre CounterclockwiseCentreClockwiseCentreTotal air consumption, Q1, is obtained by adding up the air consumption of each stroke,which is shown in the table below.Air ConsumptionO.D.

Series MSZAuto Switch Precautions 1Be sure to read before handling.Warning1. Confirm the specifications.Read the specifications carefully and use this product appropriately.The product may be damaged or malfunction if it isused outside the range of specifications of current load, voltage,temperature or impact. We do not guarantee any damagein any case the product is used outside of the specificationrange.2. Keep wiring as short as possible.As the length of the wiring to a load gets longer, the rush currentat switching ON becomes greater, and this may shortenthe products life. (The switch will stay ON all the time.)1) For an auto switch without a contact protection circuit, use acontact protection box when the wire length is 5 m or longer.2) Even if an auto switch has a built-in contact protection circuit,when the wiring is more than 30 m long, it is not ableto adequately absorb the rush current and its life may be reduced.It is again necessary to connect a contact protectionbox in order to extend its life. Please contact SMC in thiscase.3) Although wire length should not affect switch function, usea wire that is 100 m or shorter.3. Do not use a load that generates surge voltage.If a surge voltage is generated, possibly resultingin the shortening of product life.If driving a load such as a relay that generates a surge voltage,use a switch with a built-in contact protection circuit or usea contact protection box.Although a zener diode for surge protection is connected atthe output side of a solid state auto switch, damage may stilloccur if a surge is applied repeatedly. When directly driving aload which generates surge, such as a relay or solenoid valve,use a type of switch with a built-in surge absorbing element.4. Cautions for use in an interlock circuitWhen an auto switch is used for an interlock signal requiringhigh reliability, devise a double interlock system to safeguardagainst malfunctions by providing a mechanical protectionfunction, or by also using another switch (sensor) togetherwith the auto switch. Also perform periodic inspection and confirmproper operation.5. Do not disassemble the product or make anymodifications, including additional machining.Design and SelectionCaution1. Take precautions when multiple cylindersare used close together.When two or more auto switch actuator are lined up in closeproximity to each other, magnetic field interference may causethe switches to malfunction. Maintain a minimum separation of40 mm. (When the allowable interval is specified for each series,use the indicated value.)2. Take precautions for the internal voltagedrop of the switch.1) Switches with an indicator light (Except D-A96/A96V)• If auto switches are connected in series as shown below, takenote that there will be a large voltage drop because of internalresistance in the light emitting diodes. (Refer to internalvoltage drop in the auto switch specifications.)[The voltage drop will be “n” times larger when “n” autoswitches are connected.]Even though an auto switch operates normally, the load maynot operate.• Similarly, when operating below a specified voltage, it is possiblethat the load may be ineffective even though the autoswitch function is normal. Therefore, the formula belowshould be satisfied after confirming the minimum operatingvoltage of the load.SupplyvoltageInternal voltage– >drop of switchLoad2) If the internal resistance of a light emitting diode causes aproblem, select a switch without an indicator for light(MODEL D-A90/A90V)3) Generally, the internal voltage drop will be great with a 2-wiresolid state auto switch.Also, note that a 12 V DC relay is not applicable.3. Pay attention to leakage current.With a 2-wire solid state auto switch, current (leakage current)flows to the load to operate the internal circuit even when inthe OFF state.Current to operate load >(OFF condition)Minimum operatingvoltage of loadLeakagecurrentIf the condition given in the above formula is not met, it will notreset correctly (stays ON). Use a 3-wire switch if this specificationcannot be satisfied.Moreover, leakage current flow to the load will be “n” times largerwhen “n” auto switches are connected in parallel.4. Ensure sufficient clearance for maintenanceactivities.When designing an application, be sure to allow sufficientclearance for maintenance and inspections.Back page 2

Series MSZAuto Switch Precautions 2Be sure to read before handling.Mounting and AdjustmentWarning1. Instruction manual.Install the products and operate them only after reading theinstruction manual carefully and understanding its contents. Alsokeep the manual where it can be referred to as necessary.2. Do not drop or bump.Do not drop, bump or apply excessive impacts (300m/s 2 orgreater for reed switches and 1000m/s 2 or greater for solid stateswitches) while handling.Although the body of the switch may not be damaged, the insideof the switch could be damaged and cause a malfunction.3. Mount switches using the proper tighteningtorque.When a switch is tightened above the torque specification, themounting screws, or switch may be damaged. On the otherhand, tightening below the torque specification may allow theswitch to slip out of position. (Refer to switch mounting foreach series regarding switch mounting, moving, and fasteningtorque, etc.)4. Mount a switch at the centre of the operatingrange.Adjust the mounting position of an auto switch so that the pistonstops at the centre of the operating range (the range inwhich a switch is ON). (The mounting positions shown in thecatalogue indicate the optimum position at the stroke end.) Ifmounted at the end of the operating range (around the borderlineof ON and OFF), operation will be unstable.When the D-M9 auto switch is used to replace old series autoswitch, it may not activate depending on operating conditionbecause of its shorter operating range.Such as• Application where the stop position of actuator may vary andexceed the operating range of the auto switch, for example,pushing, pressing, clamping operation, etc.• Application where the auto switch is used for detecting anintermediate stop position of the actuator. (In this case thedetecting time will be reduced. )In these applications, please set the auto switch to the centreof the required detecting range.5. Securing the space for maintenanceWhen installing the products, please allow access for maintenance.Caution1. Do not carry an actuator by the auto switchlead wires.Never carry a cylinder by its lead wires. This may not onlycause broken lead wires, but it may cause internal elements ofthe switch to be damaged by the stress.2. Fix the switch with the appropriate screwinstalled on the switch body. If using otherscrews, switch may be damaged.WiringWarning1. Confirm proper insulation of wiring.Be certain that there is no faulty wiring insulation (such ascontact with other circuits, ground fault, improper insulationbetween terminals, etc.). Damage may occur due to excesscurrent flow into a switch.2. Do not wire in conjunction with power linesor high voltage lines.Wire separately from power lines or high voltage lines, avoidingparallel wiring or wiring in the same conduit with these lines.Control circuits containing auto switches may malfunctiondue to noise from these lines.Caution1. Avoid repeatedly bending or stretching leadwires.Broken lead wires will result from repeatedly applying bendingstress or stretching force to the lead wires.2. Be sure to connect the load before power isapplied.If the power is turned ON when an auto switch is not connectedto a load, the switch will be instantly damaged because ofexcess current.3. Do not allow short circuit of loads.If the power is turned ON with a load in a short circuitedcondition, the switch will be instantly damaged because ofexcess current flow into the switch.D-M9, D-M9W(V) and all models of PNP output typeswitches do not have built-in short circuit protection circuits. Ifloads are short circuited, the switches will be instantlydamaged, as in the case of reed switches.Take special care to avoid reverse wiring with the brown [red]power supply line and the black [white] output line on 3-wiretype switches.Back page 3

Series MSZAuto Switch Precautions 3Be sure to read before handling.Caution4. Avoid incorrect wiring.A 24 VDC switch with indicator light has polarity. The brown[red] lead wire is (+), and the blue [black] lead wire is (–).1) If connections are reversed, the switch will still operate, butthe light emitting diode will not light up.Also note that a current greater than the maximum specifiedone will damage a light emitting diode and make itinoperable.Applicable models: D-A93, A93V1) If connections are reversed on a 2-wire type switch, theswitch will not be damaged if protected by a protection circuit,but the switch will always stay in an ON state. However,it is still necessary to avoid reversed connections, sincethe switch could be damaged by a load short circuit in thiscondition.2) If connections are reversed (power supply line + and powersupply line –) on a 3-wire type switch, the switch will be protectedby a protection circuit. However, if the power supplyline (+) is connected to the blue wire and the power supplyline (–) is connected to the black wire, the switch will be damaged.D-M9(V) does not have built-in short circuit protection circuit.Be aware that if the power supply connection is reversed (e.g.(+) power supply wire and (–) power supply wire connection isreversed), the switch will be damaged.5. When the cable sheath is stripped, confirmthe stripping direction. The insulator may besplit or damaged depending on the direction.(D-M9(V) only)Recommended toolModel nameWire stripperWiringModel no.D-M9N-SWY∗ Stripper for a round cable (ø2.0) can be used for a 2-wiretype cable.Operating EnvironmentWarning1. Never use in an atmosphere of explosive gases.The construction of the auto switch is not intended to preventexplosion. Never use in an atmosphere with an explosive gassince this may cause a serious explosion.2. Do not use in an area where a magnetic fieldis generated.The auto switch will malfunction or the magnets inside of anactuator will become demagnetised if used in such an environment.3. Do not use in an environment where the autoswitch will be continually exposed to water.The switch satisfies the IEC standard IP67 construction (JIS C0920: watertight construction). Nevertheless, it should not beused in applications where it is continually exposed to watersplash or spray. This may cause deterioration of the insulation orswelling of the potting resin inside switch causing a malfunction.4. Do not use in an environment with oil orchemicals.Consult with SMC if the auto switch will be used in an environmentwith coolant, cleaning solvent, various oils or chemicals.If the auto switch is used under these conditions for even ashort time, it may be adversely effected by a deterioration ofthe insulation, a malfunction due to swelling of the potting resin,or hardening of the lead wires.5. Do not use in an environment with temperaturecycles.Consult with SMC if the switch is used where there are temperaturecycles other than normal temperature changes, as theymay adversely affected the switch internally.6. Do not use in an environment where there isexcessive impact shock.When excessive impact (300 m/s 2 or more) is applied to areed switch during operation, the contact point maymalfunction and generate a signal momentarily (1 ms or less)or cut off. Consult with SMC regarding the need to use a solidstate switch in a specific environment.7. Do not use in an area where surges are generated.When there are units (such as solenoid type lifters, high frequencyinduction furnaces, motors, etc.) that generate a largeamount of surge in the area around an actuator with a solidstate auto switch, their proximity or pressure may cause deteriorationor damage to the internal circuit of the switch. Avoidsources of surge generation and crossed lines.Back page 4

Series MSZAuto Switch Precautions 4Be sure to read before handling.Operating EnvironmentCaution1. Avoid accumulation of iron debris or closecontact with magnetic substances.When a large accumulated amount of ferrous waste such asmachining chips or welding spatter, or a magnetic substance(something attracted by a magnet) is brought into close proximityto an actuator with auto switches, this may cause the autoswitches to malfunction due to a loss of the magnetic forceinside the actuator.2. Contact SMC for the water resistance ability,the elasticity ability of the lead wire, and thewelding site etc.3. Do not expose the product to direct sunlightfor an extended period of time.4. Do not use the product in locations where itis exposed to radiant heat.MaintenanceWarning1. Perform the following maintenance periodicallyin order to prevent possible danger dueto unexpected auto switch malfunction.1) Securely tighten switch mounting screws.If screws become loose or the mounting position is dislocated,retighten them after readjusting the mounting position.2) Confirm that there is no damage to the lead wires.To prevent faulty insulation, replace switches or repair leadwires, etc., if damage is discovered.3) Confirm that the green light on the 2-colour display typeswitch lights up.Confirm that the green LED is ON when stopped at the setposition. If the red LED is ON, when stopped at the set position,the mounting position is not appropriate. Readjustthe mounting position until the green LED lights up.2. Perform the maintenance procedures outlinedin the instruction manual.If the maintenance procedures are performed improperly, malfunctionor damage to the machinery or equipment may occur.3. Removal of equipment, and supply/exhaustof compressed air.When an equipment is serviced, first confirm that measuresare in place to prevent workpieces from dropping run-awayequipment, etc. Then cut the supply pressure and power, andexhaust all compressed air from the system using the residualpressure release function.When the equipment is operated after remounting or replacement,first confirm that measures are in place to prevent lurchingof actuators, etc. Then confirm that the equipment isoperating normally.Back page 5

Series MSZ / Specfic product precautionsBe sure to read before handling.Please refer to “Precautions for Handling Pneumatic Devices” (M-03-E3A)for Safety Instructions and Actuators/Auto Switch Precautions.Operation which requires no stop at the centre positionCaution1. End-to-end operation without stopping at the centreposition includes situations such as deceleratingor pausing around the centre position. Avoid usefor applications in which speed change is aproblem during end-to-end operation since theproduct may stop for max. 0.1s during high-speedrotation (0.2s/90°) and for max. 0.5s during lowspeedrotation (1s/90°).CautionBreathing hole1. The breathing holes located on the intermediatestopping part repeatedly absorb and release air.Care should be taken not to block the holes whenmounting the product.Behaviour in the power-off conditionCaution1. When a pressure-centre (PAB) type 3-positionsolenoid valve is used, the table as well as thesolenoid valve return to the centre position whenthe power is cut due to blackouts, etc.If the return position must be at a particular rotationend, either counterclockwise or clockwise when ablackout occurs, use two 3-port solenoid valves asshown below. Please refer to the table below for thesolenoid valve type to be used.PValve1PValve2CautionMountingBreathing hole1. Although any mounting direction is available withthis product, when the gravity acting on the loadacts in the direction of table rotation (e.g. the centreof gravity for the load and the rotation centre arenot aligned when the rotation shaft is horizontal),stable rotation speed cannot be obtained.In particular, since a meter-in speed controller controlsthe operation of rotating from the end to centre position,when the operating direction is the same as thedirection the gravity acts on, then gravitationalacceleration cannot be controlled, this may causebouncing when it stops.Backlash in the table at the centre positionCaution1. Backlash in the table in the rotating direction can becontrolled by adjusting the centre position properly.However, backlash (about 0.1°) may occur as therotation speed increases. If this causes any problemsduring operation, readjust the centre position.Reset potionCounterclockwise rotation endClockwise rotation endValve1Normally closedNormally openValve2Normally openNormally closedIf the stopped position must be held when the power iscut, use two 5-port double solenoid valves as shownbelow.
