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 PSF111 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.
As with all DesignFlex-branded series pressure and vacuum switch components, and through Variohm´s own design and production service, application customised engineering is available with modified mechanical and electrical interfacing and customer specified electrical lead lengths with connector options.
Variohm EuroSensor supports the complete range of DesignFlex pressure and vacuum switching components and accessories and is also a distribution partner for leading sensor manufacturers as well as a sensor component and sensing systems manufacturer with in house design and assembly expertise.
