Type: ZE, Slow action contact miniature pressure switches for printed circuit boards with 6.35mm pitch, metal fitting, SPNO contact


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 50mbar, other values are achievable from 20 to 400 mbar.

Electrical connection: printed circuit terminal, dia 1 mm, 12.7 mm spacing.

Maximum pressure: 2 bars (29 PSI).

Ambient temperature limits: 0 to 85°C.
