Pressure Switch 700-5,000 PSI

Hyvair’s PS20-5K pressure switch delivers reliable, adjustable pressure monitoring from 700 to 5,000 psi for demanding hydraulic applications. Designed with a rugged iron body and piston-actuated construction, it withstands high system pressures while maintaining consistent performance in hydraulic, lubricating, and light oil circuits.

The 1/4″ female NPT port allows straightforward integration into existing hydraulic lines, and the compact form factor makes it ideal where space is limited or panel mounting is required. A DIN 43650 Table A electrical connector provides a secure, industry-standard interface for wiring and simplifies service or replacement.

At the heart of the PS20-5K is a durable microswitch rated for up to 20 switching cycles per minute, with ±3% repeatability to help protect pumps, motors, and critical components from overpressure conditions. Users can choose a standard internal adjustment screw or the optional “K” knurled adjustment knob with a clear pressure readout scale for fast, tool-free setpoint changes and easy visual verification.

Engineered for versatility, the PS20 series operates in ambient temperatures from -25°C to 80°C (approx. -13°F to 175°F) and handles viscosities up to 450 SSU (1000 mm²/s), making it suitable for a wide range of industrial hydraulic systems. Common, normally open, and normally closed contact options support flexible control logic for alarms, interlocks, and pump control.

Whether used for system shutdown, pump start/stop, or pressure-dependent signaling, the PS20-5K offers a compact, cost-effective solution with the durability and accuracy required in industrial fluid power environments.
