ELECTRICAL Multi-pump soft-starter handles pumps from 1–15kW Ralspeed has announced a multi-pump soft-starter for controlling and protecting pumps from 1–15kW, thus avoiding the need to use different soft-starters for each size of pump. The system is based on an overload protection relay that can be set to match the pump in use via a rotary switch calibrated in kW – no other settings are needed. A digital display shows the kW rating selected, the instantaneous running current and the status of the softstarter. It can also show data from the last eight trips, enabling problems to be diagnosed rapidly. The soft-starters are equipped with a load-break isolator, a hand/auto selector switch, a door-mounted e-stop pushbutton, and an analogue output proportional to the motor current. The overload relay provides earth leakage protection and can be used with thermistors to monitor motor temperatures. Ralspeed 01254 582345 www.ralspeed.com Light curtains have 14ms response Panasonic has introduced a slim safety light curtain which it describes as one of the smallest on the market. The IP67- protected SUNX SF4B Type 4 light curtain offers 10, 20 or 40mm beam pitches and comes in three versions – for finger, hand and arm, or foot protection. All types can be wired to provide NPN or PNP transistor outputs. The curtains offer a 14ms response time, regardless of the number of channels, the beam axis pitch, or the number of curtains connected in series. The rapid response time, coupled with the small beam pitch of the finger protection version, allows the light curtain to be installed closer to danger points than conventional models. The body and the cylindrical inner casing that protect the electronics ensure that the curtains conform to IP65 and IP67. An easy-to-read digital error indicator makes troubleshooting easy. Panasonic Electric Works UK 01908 231555 www.panasonic-electric-works.co.uk Solid-state relays are ‘smallest’ Carlo Gavazzi claims to be offering the first UL-certified solid-state relay and contactor combinations in a 17.5mmwide format. The RG series SSRs include panel-mounting versions rated up to 600V AC and 90A AC, and versions with integrated heatsinks that can handle 20A AC in 17.5mm widths and 30A AC in 22.5mm widths. With a 100kA short-circuit capability, the relays are suitable for silent switching of motors and will resist up to 5g of vibration. DC versions can be controlled by 4–32V DC, while AC versions can be controlled by 20–275V AC or 24–190V DC. There is a choice of zero-crossing or instanton (random) mains voltage switching. Over-voltage protection is provided across the output. A removable IP20 cover allows power terminals to accept ferrule, ring and fork type terminations. Control status is indicated by LEDs. Carlo Gavazzi UK 01252 339600 www.carlogavazzi.co.uk FLUID POWER Stainless-steel cylinders resist washdowns SMC has developed and improved several stainless-steel pneumatic products for wet and washdown applications. For example, its portfolio now includes the CJ5-S and CG5-S airoperated cylinders for food-processing machinery where corrosion and heat resistance are often essential. The cylinders, in bore sizes from 10–100mm, have an all-stainless steel external construction and are fitted with a scraper to prevent water from entering the cylinder. There are also two improved stainless-steel fittings ranges – KQG2 and KFG2. The KQG2 one-touch fittings, based on the earlier KQG series, are about 30% smaller and more than 60% lighter than conventional models and come in 17 versions designed to operate with fluids from -5ºC to 150ºC. The insert fitting type series KFG2, which operates with fluid temperature from -65ºC to 260ºC, is more than 40% smaller and nearly 40% lighter than conventional models. SMC is also offering a stainless-steel speed controller (series ASG) with one-touch fittings for ambient operating fluids from -5ºC to 60ºC, and operating pressures from 0.1– 1MPa. SMC Pneumatics (UK) 01908 555017 www.smcpneumatics.co.uk Linear drives combine power, accuracy and flexibility Parker Hannifin’s Parker- Origa division has launched a range of magnetically-coupled pneumatic rodless cylinders with a single rod and rotating carriage, or with integrated anti-rotating guides. The P1Z linear drives, which consist of a stainless-steel pneumatic cylinder body fixed between two end-plates, can be used at low speeds from 0.05m/s and can deliver thrust forces up to 942N. A hard anodised aluminium carriage is fitted to the outside of the cylinder body, with the carriage and the cylinder piston coupled magnetically using annular magnets. In the unguided version, the carriage can rotate through 360 degrees around the cylinder, with adjustable pneumatic end-of-stroke cushioning and air ports at both stroke ends. The guided version uses two rigid chromeplated steel guide rails, with optional magnetic sensors for precise positioning. They can be fitted with elastomeric bumpers for light loads or hydraulic shock absorbers for heavier loads. Both versions can be mounted horizontally or vertically and are available in bore sizes from 16–40mm and in stroke lengths up to 2m.

Due to transponder technology this system meets the highest safety levels. The set is suitable for hinged and sliding doors. Three semiconductor outputs provide the status: door closed (1), bolt detected (2), safely locked (3). In addition two safe pulsed semiconductor outputs are activated after a safe condition is achieved. Curious?
