Home / Controls, safety & Regulation / Pressure switches / Type ZF: Slow action contact miniature vacuum switches, 6.35 x 0.8 mm terminals, metal fitting SPNO contact
Uses: Low voltage, high sensivity
Main applications: Electronic printed circuit. This vacuum 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: air or water
Fitting: brass (stainless steel on request)
Pressure: negative (Vacuum)
Housing: PA66, UL94 VO
Contact: single pole normally open at atmospheric pressure, slow make.
Electrical rating:
– Silver contact: max 1A 250V
– Gold plated contact: max 100 mA, 24V
Action: momentary, close on vacuum increase (=decrease of absolute pressure).
Set point calibration: factory calibrated and sealed, not field adjustable
Set point calibration limits (relative pressure): standard calibration minus 50mbar, other values are achievable from minus 20 to minus 200 mbar
Electrical connection: two 6.35 x 0.8 mm quick connect terminals
Maximum pressure: 2 bars (29 PSI)
Maximum vacuum: minus 500 mbar (relative pressure)
Ambient temperature limits: 0 to 85°C
Available pressure inlet fittings ①
