SERIES PSF100A

DESIGNFLEX PSF100A SERIES

The DesignFlex PSF100A series are miniature, ultra-sensitive pressure, vacuum, and differential pressure switches known for their patented resistance to shock and vibration. They are designed for low-current applications and offer a long mechanical life.

DESIGNFLEX PSF100A SERIES

KEY FEATURES
Sensing Type: Capable of sensing positive pressure, vacuum, or differential pressure.
Set Points: Fixed set points are available from 0.1″ to 50.0″ of water column (H₂O), which is approximately 0.004 to 1.804 psi.
Switch Type: SPST normally open, double-make/double-break switch configuration with dual gold inlay contacts.
Shock & Vibration Resistance: Patented dual diaphragm/dual contact design prevents false actuation, meeting military standards (MIL-STD-167-1 & MIL-STD-901-D).
Operating Life: Dependable with a mechanical life of more than 20 million cycles.
Miniature Size: Compact and lightweight design, weighing less than 10 grams.
