4mm 1/2 7818 Legris Pneumatic Sensor Fitting 

Description

This sensor fitting detects pressure drop. It produces an end-of-stroke signal, pneumatic or electric when the exhaust back pressure in the cylinder disappears. They are generally used to detect the end-of-travel of a cylinder thus allowing cylinder reciprocation.

Application

They can be mounted on the cylinder, on the control valve or on a manifold block provided it is between the cylinder and the flow control.
