RS PRO Pressure Switch, G 1/4 20bar to 400bar

Zinc plated, carbon steel adjustable pressure switches from RS. Available for both hydraulic and pneumatic applications, pressure switches supply an electrical signal once the system has reached a designated pressure. The switching pressure can be adjusted to suit various set points simply by rotating a screw in the centre of the pressure switch

Fitted with a mechanical stop to prevent damage from over pressurisation
Can be mounted in any orientation
90 Cycles/min switching frequency
Long mechanical life (10^6 cycles at 70bar)
0.5A maximum load (at 250 VAC)
Accuracy 4% of set pressure
Fixed Hysteresis 10-25% (Dependent upon version)
DIN 43650 Electrical connection

These pressure switches are suitable for use in a diverse range of applications. These applications include machine building, ship building, measurement and control technology, hydraulics and pneumatics, pumps and compressors

• Pumps
• Compressed air systems
• Machine tools
• Process control equipment
• Sensors
• Hydraulics and Pneumatics
• Valves and switches

297-0052 does not include a mechanical stop and requires a 2mm allen key in order to adjust

This pressure switch can be switched between 20 – 300 Bar with a max pressure rating of 400 Bar.

Pressure Switches

Pressure switches that allow microswitch operation once a pre-set pressure is reached. K and K3 Series incorporate a mechanical stop providing over-pressure protection for the spring and microswitch. Electrical connections for all models to DIN 43650.
