Pressure drop sensor G1/4 Legris

Parker pneumatic sensor couplings have a unique sensor that detects the pressure drop when a cylinder reaches the end of its stroke.
They produce a pneumatic or electrical output when the pressure drop in the cylinder exhaust chamber falls below their back pressure threshold.

Features/Benefits:

- Easy to use

- Suitable for series changes: no adjustment of position detectors required

- With pneumatic exit

- Fully pneumatic installation
- 2 possible installations:
Permanent pressure feed (P1): produces a pneumatic signal when the back pressure threshold is reached
Fed from the control valve-cylinder circuit on the opposite side: no unexpected pneumatic signal (S) can occur during pressurisation due to the operating pressure feeding the sensor coupling (P1)

- With electrical output

- Combined electrical and pneumatic installation
- Installation only with continuous power supply (BU)
- Ensures an electrical signal when the back pressure threshold is reached
