Q25L magnetically actuated linear displacement sensor

The Q25L sensor is a magnetically actuated linear displacement sensor designed to detect piston position on pneumatic cylinders.

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

By utilising 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 utilising a series of Hall elements that sense the piston magnet and send a signal back to the processor. It has a repeat accuracy of <0.1% of the measuring range and a linear deviation of <1% of the full scale. It also features a blind zone of 20.5 mm on each end, making it suitable for space-restricted areas.
