Sensor-Ready Hydraulic Cylinders

These cylinders have a magnetic piston that can be used with tie rod-mount proximity switches (sold separately) to electronically indicate piston position. For easy interchangeability, their mounting footprint meets NFPA or NFPA and JIC (Joint Industrial Congress) industry standards. All have two hydraulic ports: one to extend the piston rod and another to retract it. Cylinders with an adjustable cushion reduce shock to internal components and lessen machine noise. Those with no cushion have a compact size.

Tie Rod-Mount Proximity Switches

Send an electronic signal to your system when the piston reaches a certain location. Mount one or two of these sensors on a cylinder tie rod; they must be flush against the cylinder tube. An LED indicator shows the piston location.

PNP (also called "sourcing") output sends energy onwards. It is most common in solid-state relays and PLCs used in the United States and Europe.

NPN (also called "sinking") output pulls energy from the circuit. It is most common in PLCs used in Asia.
