Linear Displacement Sensor with Small Blind Zones

Jan. 1, 2009
TURCK’s magnetically actuated linear displacement sensor is available with measuring ranges of 100, 125, 160 and 200 mm.

The Q25L sensor 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 even more 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 line 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.
