product presentation

Main applications :
Electronic printed circuits. Detection of low positive, negative or differential pressure. Measurement of liquid levels, air flow, filters efficiency. Very small differential, about 0.2 kPa (2 mbar, 0.03 PSI)

Membranes: Silicone, dia 22mm.

Fluid: Air only
Fitting: Two plastic spouts dia 4mm for soft PVC tube 3 × 6mm (⅛”) Pressure: Differential
Housing: PA66
Contact: Single pole normally open, slow make and break.

Electrical rating:
- Silver contact: max 1A 250VAC resistive
- Gold plated contact: max 100 mA, 24VDC
Action: Momentary, close by pressure rise on positive pressure inlet
Set point calibration: Factory calibrated and sealed
Set point calibration limits: From -/+1 to -/+60 kPa (-/+ 10 to -/+ 600 mbar, -/+0.15 to -/+9 PSI) Differential: Less than 0.5 kPa (5 mbar, 0.07 PSI)
Electrical connection: printed circuit terminal, dia. 1mm, 12.5mm distance
Maximum operating pressure: -/+ 90kPa(-/+ 900mbar, -/+ 13PSI)
Bursting pressure: > 4bar (0.4Mpa, 60PSI)
Ambient temperature limits: Air: -10 ~ 85°C (14 to 185°F)
Note: 10 kPa= 100 millibars = 1.45 PSI= 40 inches of water = 1016mm of water.
