Variohm EuroSensor (United Kingdom) - New from the World Magnetics Company and available in the UK and Europe from Variohm EuroSensor, the DesignFlex™ PSF111 series environmentally sealed pressure/vacuum switch is designed for challenging switching tasks where dust and water ingress prevention is essential.

The waterproof snap-action switch suits pressure and vacuum configurations with switching ranges from -822 to 4137 mbar (-11.9 to 60 psi) and is available in a wide choice of port configurations and mounting options.

With a moulded polycarbonate housing and encapsulated electrical components, the PSDF111 also features field adjustable pressure and vacuum set points - and with a polyurethane diaphragm as standard and optional Teflon material, the switch is suitable for most common pneumatic and fluid systems. The standard current rating across the series is 3 A with 4 A available on request. The operating voltage is 12 VDC / 125 VAC and the temperature range is -40 to + 85 °C. The compact switch housing typically measures approximately 25 mm in height, length and width, with a 1/8-27 threaded port connection protruding 18 mm.
