Subminiature Pressure Switch

Nov. 25, 2014

Gems Sensors & Controls (Gems) announces the global market launch of its Model PS61P OEM subminiature pressure switch, offering reliable medium-to-high pressure monitoring within space constrained applications. Design of the Gems Model PS61P incorporates a hardened alloy steel piston actuator for expanded overpressure performance. The low mass unit occupies a 24 mm diameter hex footprint and measures less than two inches. The switch is designed to reliably monitor standard pressures from 510 to 4350 PSI (35 to 300 bar), with an enhanced burst pressure rating of 22,000 PSI (1517 bar). This makes the Model PS61P especially suitable for higher pressure, cyclic pressure and pressure spike environments.

In addition, its exceptional size-to-performance ratio is ideal for demanding off-highway vehicle, agricultural and construction equipment applications, particularly where space constraints and performance limitations have traditionally otherwise excluded OEM pressure switch specification. The Gems Model PS61P is highly configurable off-the-shelf, with choices of alternate seals, fittings, and electrical terminations to meet unique OEM, aftermarket, and retrofit requirements. As a standard catalog product, the Model PS61P is available for immediate online purchase at Test samples are available within just a few business days.
