Type ZH: Low pressure, slow action contact differential pressure switches for it printed circu boards with 6.35mm pitch SPNO contact

Uses: Low voltage, high sensivity

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 2 millibars

Membranes: EPDM, dia 22 mm. Silicone or NBR on request

Fluid: water or air (no liquid input on the negative pressure inlet)

Fitting: two plastic spouts dia 4 mm for soft PVC tube 3×6 mm (1/8”)

Pressure: Differential

Housing: PA66, UL94 VO

Contact: single pole normally open, slow action.

Electrical rating:

– Silver contact: max 1A 250V

– Gold plated contact: max 100 mA, 24V

Action: momentary, close by pressure rise on positive pressure inlet

Set point calibration: factory calibrated and sealed, not field adjustable

Set point calibration limits: from 10 to 400 mbar

Differential: less than 5 mbar

Electrical connection: printed circuit terminal, dia 1.2 mm,12.7mm spacing

Maximum pressure: 500 mbar (7 PSI)

Ambient temperature limits: 0 to 85°C
