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 2 inches. The switch is designed to reliably monitor standard pressures from 510-4,350 psi (35-300 bar) with an enhanced burst pressure rating of 22,000 psi (1,517 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.
