Lehigh Fluid Power
Position Sensing Cylinders

Lehigh Position Sensing
Available on All Series Cylinders

There are four main types of position sensing devices for pneumatic and hydraulic cylinders:

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

See our catalog for descriptions of these systems, but note one important thing:

Tie-rod mount limit switches that are adjustable throughout the cylinder stroke length are commonly available on pneumatic cylinders. We also offer this on our pressure rated hydraulic cylinders!

This is possible because the tube material in this JHDH series is not steel. Never has been. For 60 years we have built our pneumatic and pressure rated hydraulic cylinders with tubes made of tempered brass. This material enables us to feature the same magnetic piston sensing option in hydraulics that is common in pneumatics.

And this same limit switch option is also available on our line of all-stainless steel cylinders!

Specials:
Don't see what you need? We have a long history of producing custom design cylinders that are specific to a customer's application. We welcome the one-of-a-kind special as well as the OEM quantity. So whether your requirements are frequent or few, standard or custom, we are here to help.
