E2JE2JPrecautionsObserve the following precautions to ensure safety.1. Do not use the Sensor in an environment where it will be exposed to inflammable or explosive gases.2. Do not attempt to disassemble, repair, or modify the Sensor.3. Be careful not to connect the power source with the polarities in reverse.4. Do not short-circuit the loads.5. Do not use the Sensor at voltages exceeding the rated voltage.Correct UseHandling$ Do not use the Sensor outdoors.$ Do not wire the Sensor alongside a high-tension or power line.$ Do not use portable telephones or transceivers near the Sensor.Be sure to ground the Mounting Brackets.$ Do not use the Sensor in an environment where it will be exposedto chemicals, particularly chemical solutions or oxidizing acids.MountingBe sure that the tightening torque does not exceed the followingvalue.Mutual InterferenceWhen mounting more than two Sensors face to face or side by side,ensure that the minimum distances given in the following table aremaintained.Distance E2J-W10MA E2J-W20MAE 20 mm 70 mmF 30 mm 50 mmALocationTorque0.54N S m {5.5 kgf S cm} max.Effects of Surrounding MetalBefore mounting the Sensor, be sure that the Sensor will be separatedfrom surrounding objects as shown in the following illustration.Sensing sideSensorSensing sideSensorMetal objectBe sure toground themetal object.Metal objectBe sure toground themetal object.Dimension E2J-W10MA E2J-W20MAB 10 mm 20 mmC 20 mm 40 mmEffects of Static ElectricityBe sure to discharge static electricity before detecting objects thatare greatly affected by static electricity.7

E2JE2JAdjustment Procedure1Step Sensing Sensitivity adjuster AdjustmentSensing object--- Obtain the sensing distance X from theset distance S divided by 0.75.Determine S so that X will be less thanthe maximum sensing distance.23Sensing objectSensing objectLocate the Sensor so that the distancebetween the Sensor and sensing objectis X. Turn the sensitivity adjusterclockwise until the red sensing indicatorof the Sensor Head is lit.--- Return the Sensor to the previousposition so that the distance betweenthe Sensor and sensing object is S.Note: After completing sensitivity adjustment, mount the provided cover on the Amplifier Unit to prevent mis-operation.$ The maximum sensing distance will drop depending on the dimensions and material of the sensing object. Refer to Engineering Data.$ Since a different adjustment procedure must be taken if the ambient temperature is outside the specified temperature range (0!Cto40!C),contact your OMRON sales representative.Cord$ Be sure that the bending radius of the cord is more than 5 mm.$ Use the XS3W-M421-40j-R with connectors (M8-screwmountingtype) as the extension cord. The maximum cord lengthis 3 m (extension section: 2 m).Mounting and Dismounting the Amplifier UnitMounting1. Mount the front part of the amplifier to the mounting bracketprovided with the amplifier or a DIN track.2. Press the rear part of the amplifier onto the mounting bracketor DIN track.Rear partFront partFixture railDIN track or Mounting BracketDismounting3. Pull the fixture rail with a flat-blade screwdriver so that theAmplifier Unit can be dismounted with ease.ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.To convert millimeters into inches, multiply by 0.03937.
