Parker Threshold sensors PSBJ731-4

The plug-in threshold sensors provide feedback information on pneumatic cylinder status in one of three possible outputs: pneumatic, electric, or electronic. Mounted into the cylinder port, these devices monitor the back pressure of the cylinder's exhaust. When the cylinder's piston stops, the back pressure rapidly drops and the threshold sensor provides the desired output.

Ideal for variable stroke applications, such as robotics, where other sensor type devices, such as limit switches, are impractical. These devices provide a signal whenever the cylinder stops motion. The threshold sensor consists of two complementary sub assemblies; (1) the banjo fitting and (2) the plug-in sensor element. In all cases, the sensor is easily plugged into the banjo fitting and locked in place with a spring clip. The banjo fitting is designed to accept (piggy backed) other functional fittings, such as flow controls or blocking valves.  Simply select the sensor based on the type of feedback signal that best fits the application.
