Fluid: water or air
Fitting: Plastic
Pressure: positive
Housing: PA66, UL94 VO
Contact: single pole normally open, slow make.
Electrical rating:
- Silver contact: max 1A 250V
- Gold plated contact: max 100 mA, 24V
Action: momentary, close on pressure rise.
Set point calibration: factory calibrated and sealed, not field
adjustable
Set point calibration limits: standard calibration 150mbar, other values are
achievable from 100 to 1300 mbar
Electrical connection: 6.35 x 0.8 mm quick connect terminals
Maximum pressure: 2 bars (29 PSI)
Ambient temperature limits: 0 to 85°C
Available pressure inlet fittings 1
