Gems Sensors Series
Elastomer Diaphragm OEM Subminiature Pressure Switch
Quick Specs...
- Formerly PS-JL Model
- 5 to 300 psi (0.345 to 20 bar)
- Ideal for pneumatic and low pressure hydraulic applications
- Adjustable or Factory Set
Overview / Design Principle:
These compact pressure switches are designed for OEM applications. Made economical by using metal blade contacts in lieu of microswitches, this series features long-lasting Elastomer diaphragms in three materials. Elastomer diaphragms offer increased sensitivity and life for applications without temperature extremes.
