ULTIMHEAT : Differential pressure switch for printed circuits. Type ZH

Low pressure, slow action contact differential pressure switches for it printed circu boards with 6.35mm pitch
SPNO contact : Type ZH
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 3x6 mm (1/8”)
