RS PRO Pressure Switch, G 1/4 0.2bar to 2.5 bar

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

The adjustment on these pressure switches is done by a 2mm Allen Key. The hex socket adjusting screw is hidden down the hole where the screw fits to fasten the electrical block switch. So you need to undo and remove the screw then drop the 2mm Hex key down the recess to adjust.

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.
