The Parker pneumatic sensor fittings has a unique sensor that detects the pressure drop when a cylinder reaches the end of its stroke.
They produce a pneumatic or electric output signal when the pressure drop in the exhaust chamber of the cylinder goes below their back pressure threshold.
Features
Easy-to-Use
Suited to changes of series: no adjustment to position detectors is necessary
With Pneumatic Output
Totally pneumatic installation
2 possible installations: Supplied with permanent pressure (P1): produces a pneumatic signal when the back pressure threshold is reached Supplied from the control valve-cylinder circuit on the opposite side: no unexpected pneumatic signal (S) can appear during pressurisation due to the actuating pressure which supplies the sensor fitting (P1)
With Electrical Output
Combined electrical and pneumatic installation
Installation with continuous electrical supply only (BU)
Guarantees an electrical signal when the back pressure threshold is reached
