Position Sensing Cylinders & Switches

There are 4 main types of position sensing devices for cylinders (applies to both pneumatic and hydraulic):

  • Tie rod mounted limit switches that are actuated by a magnetic piston.
  • End-of-stroke proximity switches that are actuated by the cylinder cushion boss.
  • Linear displacement transducer constructed as a probe inside the cylinder rod.
  • Servo-type positioner for an air cylinder operating by force balance.

Tie-rod mount limit switches that are adjustable throughout the cylinder stroke length are commonly available on all pneumatic cylinders.
