Gems Sensors Series Pressure Switch
Ultra-Long Life Pressure Switches
Quick Specs...
- Formerly PDPA/PDPF Model
- 0.75 to 15 psi (57.71 to 1034 mbar)
- 1,000,000 Cycle Life Typical
- Factory Set or Field Adjustable Set Points
Overview / Design Principle:
For low pressure applications, the longevity of our PS11 Series is hard to beat. A life expectancy of 1 million cycles means long-term reliability. Their snap-action microswitch resets automatically and meets or exceeds industry standards. Brass housing offers chemical resistance at an affordable price.
