Each limit switch sends its signal to the controller on a dedicated line. The controller then interrupts the motion avoiding that the positioner moves until the hard stop and gets damaged. PI positioners have mechanical, noncontact optical or Hall-effect limit switches. Linear Encoder The linear encoder is an incremental sensor for capturing changes in position.
