K Series

From the trusted RS PRO brand, a series of adjustable pressure switches designed for hydraulic and pneumatic applications. Designed to detect a rise or fall in fluid pressure, the durable switches provide an electrical signal once the setpoint pressure is reached. Pre-set pressure is adjusted via a graduated knob which can be locked with a grub screw. Clockwise to increase the pressure and anti-clockwise to decrease the pressure. Mechanical stops protect both the spring and the micro-switch from over pressurisation.

Robustly constructed from anodised aluminium, the RS PRO pressure switches can be mounted in any orientation making them easy to install in a wide range of industrial environments. Connection via a ¼” BSPF parallel thread.

Features and Benefits

• Anodised aluminium construction

• Can be mounted in any orientation

• 120 Cycles/min switching frequency

• Long mechanical life (10^6 cycles at 70bar)

• 0.5A maximum load (at 250 VAC)

• Accuracy ± 1% of set pressure

• Fixed Hysteresis 15% of full-scale reading

• Wide temperature range -20° to +80°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

• ¼” BSP Female G (parallel thread)

• Compact and cost-effective

Applications

RS PRO Adjustable pressure switches are suitable for a diverse range of industrial applications. Due to their versatility and simple mounting 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

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.
