Turck has created a twin-set sensor to augment its line of BIM-UNT cylinder position sensors. The twin-set is comprised of two BIM-UNT sensing heads connected by an over-moulded cable. The power and signal wires are then combined into an integral M12 connector on the sensor. The user therefore only has to use one 4-wire cord to connect the BIM-UNT twin-set sensor to a PLC. It is especially useful for detecting the extended and retracted position of the cylinder’s piston for longer cycles, and has high sensitivity and switching accuracy. “It is also useful in places where multiple cylinders are installed, as it only needs one wire harness. This helps cut installation time and wiring costs,” says Suchi Deshpande, product specialist with Turck’s sensor division.
The BIM-UNT is a universal magnetic field sensor that detects the position of a piston on standard pneumatic cylinders. It is highly immune to EMC, polarity protected, has reliable switching points and a fast response time. This, and other design features, makes it a desirable alternative to traditional cylinder position sensors. With a total length of only 28 mm, the BIM is one of the most compact cylinder position sensors on the market. The active sensing faces are located directly at the end of the sensor to safely detect the piston rod’s end position on compact, short-stroke cylinders.
The sensor uses magneto-resistive, board level technology that provides improved performance and housing. The package includes a quick mount tab that helps seat the sensor in the cylinders groove – even before the screw is tightened – making single-handed mounting possible. The position of the screw has also been moved away from the cable-end to provide cable strain relief, while also ensuring the sensor remains in place if the cable is pulled.
BIM-UNT sensors include a broad range of accessories, from precision mounting to wire-strain relief products, to help install the sensors in all T-groove, dovetail, round or tie-rod pneumatic cylinders.
