New P50 Hand Adjustable Medium / High Pressure Switch

Geared for Speed and Accuracy

Introducing Paquin's new P50 Hand Adjustable Medium / High Pressure Switch

Field‑settable switching for high-pressure hydraulics and other types of mediums for stationary and mobile equipment.

Long-lasting Mechanical Life

  • Built for: high‑pressure industrial and mobile applications where quick, precise pressure protection is essential, supporting 1M mechanical cycles and 50k electrical cycles

  • Delivers: hand‑adjustable setpoints, long service life, and high ingress protection (IP65/IP67).

  • Integrates via: DIN 43650A, M12x1, AMP Superseal, Deutsch DT, or cable leads (mating connectors available).

What Paquin's P50 Pressure Switch Does 

Hydraulic systems in heavy equipment and manufacturing often need frequent setpoint tweaks as loads, fluids, or operating conditions change. Traditional switches can require tools or disassembly, extending downtime. The P50 solves this with a hand‑turn housing that lets technicians dial in the trip point quickly—then lock it in.

What’s New / Why It’s Different

  • Hand‑adjustable setpoint via the housing barrel (no tools).

  • Three pressure range options covering 725 up to 7,250 psi.

  • Contact flexibility: SPST‑NO, SPST‑NC, or SPDT.

  • Ruggedized I/O choices (DIN, M12, AMP Superseal, Deutsch) for drop‑in compatibility with common harnesses.

  • IP65/IP67 enclosures and extended temperature capability by seal selection.

Applications

  • Industrial machinery & manufacturing equipment

  • Mobile hydraulics / heavy equipment (e.g., hydraulic compactors)

  • HVAC & refrigeration, water treatment, and general fluid management.
