PS75 - Rugged Cylindrical Pressure Switch

► Side Mounted DIN Connection

► Top Mounted Electrical Connection

► 5 to 6000 psi (0.35 to 414 bar)

► Wear Disc Design for Longer Life

► DPDT Models Available

Gems PS75 Series have all metal surfaces for overload stops and deliver reliable operation under extremely high pressure surges. They are designed with a wear disc and cushioning ring for increased life. The switches use a piston/diaphragm design, which combine the high proof pressure of piston technology with the sensitivity of a diaphragm design. They can be field or factory adjusted.
