RS PRO Pressure Switch, G 1/4 2bar to 40 bar / 2969989

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 BSPF parallel thread. Features and Benefits.
