## Pressure Switches 

## Miniature 

Proof Pressure : 8 psi : for units where set point is 3 inches H2O or less 15 psi : for units where set point is greater than 3 inches H2O 8 psi : for units with Teflon[] diaphragm 

Shock and vibration : At zero pressure, will not make at 50 G’s shock, will not make at 10 G’s, 50 to 2,000 Hz vibration Operating Temperature : +40°F to +150°F (standard), -46°F to +205°F (contact us) 

## **Physical** 

Case Material : Polycarbonate (other materials available) Porting Options : Two 200 inches diameter barbed ports (low / high) for use with 1/8 inches to 3/16 inches ID tubing Diaphragm Material : Polyurethane (Teflon[] optional) Contact Points : Gold (dual) Electrical Connections : Terminals - 0.187 inches × 0.02 inches tab-type, for use with quick disconnects (reference AMP 2-520182-2 or equivalent) Mounting : Eyeleted for #2 screws; mounting clip or bracket available Weight : Less than 10 g 

## **Electrical** 

Current Rating : 40 mA resistive for life in excess of 20 million cycles Operating Voltage : 30 V ac / dc or less with resistive load; 120 V ac neon lamp load 

Note : For high load capabilities contact design flex for our SRF solid state relay
