The Q25L units from Turck have a repeat accuracy of less than 0.1% of the measuring range and a linear deviation of less than 1% 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.
A magnetically actuated linear displacement sensor detects piston positions on pneumatic cylinders. The Q25L, from Turck, Minneapolis, comes in measuring ranges of 100, 125, 160 and 200 mm. The unit is well-suited for applications that require precise signal transmissions over long measuring distances, such as pneumatic pumps, slides, blanking or molding systems. By using an external magnet as a position indicator, the sensor may be used in other applications such as moving platforms, point-line measurement, or equipment in which a cylinder is not present.
The Q25L detects the position of a piston on standard pneumatic cylinders using a series of Hall elements that sense a piston magnet and send a signal to a processor. Turck provides sensing, connectivity, and network products to help manufacturers improve their automated processes.
