Gems Sensors Series Pressure Switch

 Elastomer Diaphragm OEM Subminiature Pressure Switch

Quick Specs...

  • Formerly Model PMMA/PMMF
  • 50 to 300 psi (3.45 to 20 bar)
  • Adjustable or Factory Set  

Overview / Design Principle:

These compact pressure switches are designed for OEM applications. Designed to be economical by using metal blade contacts in lieu of microswitches they feature long-lasting Elastomer diaphragms. Elastomer diaphragms offer increased sensitivity and life for applications without temperature extremes.
