New environmentally sealed pressure switch
Manufactured by World Magnetics Company and available in the UK and Europe from Variohm EuroSensor, the new DesignFlex PSF111 series environmentally sealed pressure/vacuum switch is designed for challenging switching tasks where dust and water ingress prevention is required. The waterproof snap-action switch suits pressure and vacuum configurations with switching ranges from -822 to + 4137mbar (-11.9 to +60psi) and is available in a choice of port configurations and mounting options.
A moulded polycarbonate housing contains encapsulated electrical components, and the PSF111 features field-adjustable pressure and vacuum set points. A polyurethane diaphragm is fitted as standard with optional Teflon material, making the switch suitable for most common pneumatic and fluid systems. The standard current rating across the series is 3A, with 4A available on request. The operating voltage is 12V DC/125V AC and the described temperature range that the switch can be used in is -40degC to + 85degC. The switch housing is compact, typically measuring approximately 25mm in height, length and width, with a 1/8-27 threaded port connection that protrudes 18mm.
Variohm EuroSensor offers application customised engineering with modified mechanical and electrical interfacing, as well as customer-specified electrical lead lengths with various connector options. The company supports a complete range of DesignFlex pressure and vacuum switching components and accessories. It is also a distribution partner for leading sensor manufacturers, as well as a sensor component and sensing systems manufacturer itself with in house design and assembly expertise.
Variohm says that it offers "Complete sales and application support across a comprehensive range of position, force, pressure, load, and temperature sensor technologies for demanding measurement application solutions in industry, construction, agriculture, motorsports, research and mor".
