Position sensor

Turck has introduced the Q25L sensor, a magnetically actuated linear displacement device designed to detect piston position on pneumatic cylinders.

Available with measuring ranges of 100, 125, 160 and 200 mm, it is suitable for applications that require precise signal transmission over long measuring distances, such as pneumatic pumps, slides, blanking or moulding systems.

By using an external magnet as a position indicator, the sensor may be used in additional applications such as moving platforms, point line measurement or other specially designed equipment where a cylinder is not present.

The device detects the position of a piston on standard pneumatic cylinders by using a series of Hall elements that sense the piston magnet and send a signal back to the processor. A repeat accuracy is less than 0.1% of the measuring range and a linear deviation of less than 1% off the full scale.

It also features a blind zone of 20.5 mm on each end.
