Product Details

F4 Series

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.

Features & Benefits

• Robust steel construction
• 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
• Wide temperature range -25° to +85°C
• Mechanical stops to protect the spring and Micro-switch from over pressurisation
• Wide adjustment range
• N/C or N/O contacts SPDT
• Electrical connectors DIN 43650 plug to IP65
• ” BSP Male G (parallel thread)

Applications

RS PRO Adjustable pressure switches are suitable for a diverse range of industrial applications. Due to their versatility and simple design, the switches can be used in both pneumatic and hydraulic systems. Some of the more common are

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

Note

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

Note

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.
