SENSORS: TURCK’s 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 Q25L is well-suited for applications that require precise signal transmission over long measuring distances, such as pneumatic pumps, slides, blanking or molding systems. By utilizing 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. Like TURCK’s other cylinder position sensors, the Q25L detects the position of a piston on standard pneumatic cylinders by utilizing a series of Hall elements that sense the piston magnet and send a signal back to the processor. The Q25L has a repeat accuracy of less than 0.1 percent of the measuring range and a linear deviation of less than 1 percent of the full scale. It also features a blind zone of only 20.5 mm on each end, making it easy to apply in space-restricted areas.
