Home / Controls, safety & Regulation / Pressure switches / Type: ZA, slow action contact miniature pressure switches, metal fitting, SPNO contact
DIMENSIONS
Uses: Low voltage, high sensivity.
Main applications: Electronic printed circuit. This pressure switch is more sensible than snap action models and can be calibrated at lower pressure values. Very small differential.
Membranes: EPDM, dia 22 mm. Silicone or NBR on request.
Fluid: water or air.
Fitting: Brass (stainless steel on request).
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
