Twin-set sensor savings
3rd Quarter 2009
Pneumatic systems & components
TURCK has created a twin-set sensor to augment its line of BIM-UNT cylinder position sensors. The twin-set sensor comprises 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. Therefore, customers only have to use one 4-wire cordset to connect the twin-set sensor to their PLCs.
The twin-set sensor unit is especially useful for detecting the extended and retracted position of a cylinder’s piston for longer cycles, and has high sensitivity and switching accuracy. The reduced wiring harness requirement helps to lower installation time and wiring costs.
A 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.
With a total length of only 28 mm, the BIM-UNT 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.
These sensors use magneto-resistive, board-level technology that provides improved performance and housing.
The sensor comes with a quick mount tab that helps seat the sensor in the cylinder’s 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.
A broad range of accessories is available, from precision mounting to wire-strain relief products, to help install the sensors in all T-groove, dovetail, round and tie rod pneumatic cylinders.
