Most tasks involving a flat screw drive or other simple linear move requires equally simple sensing possibilities. A straightforward, linear motion detection strategy can be achieved with a straight-line actuating pin (plunger) and serves as the limit switch actuating mechanism. In the realm of medicine presses, molding machines, and machines that stop conveyors, the positioning feedback enables the use of automatic work processes as precise movement along defined trajectories is framed by extremely compact and movable bits. There is high repeatability, resistance to lateral displacement, and unwavering accuracy down to the micrometer.
