RS PRO Pressure Switch, G 1/4 5bar to 50 bar

From the trusted RS PRO brand, a series of double contact adjustable pressure switches designed for hydraulic and pneumatic applications. Designed to detect a rise or fall in fluid pressure, the robust switches provide an electrical signal once the setpoint pressure is reached. Pre-set pressure is adjusted by rotating a screw which is located in the centre of the switch head. Clockwise to increase the pressure and anti-clockwise to decrease the pressure.

Robustly constructed from steel, the RS PRO pressure switches can be mounted in any orientation making them easy to install in a wide range of industrial environments. Compact in design the switches are ideal for designs requiring a small footprint. Connection via a “BSP parallel Male thread. Electrical connection DIN 43650 IP65 plug.
