Product Description


Vacuum pressure switches
Snap action contact miniature vacuum switch




Main applications :
Vacuum detection on pumps, in particular on balneotherapy heaters, swimming pool filters, automated assembly lines. The snap-action contact allows direct control of motors or heating elements.

Main features :
Membranes: EPDM, dia. 22mm. Silicone or NBR on request.
Fluid: Water or air
Pressure port connection: PA66, 1/8” BSPT or 1/8” NPT
Pressure: Negative (Vacuum)
Housing: PA66, UL94 VO
Contact: SPDT, snap action.
Electrical rating:
- Standard rating micro-switch (low and medium vacuum only): 16A 125/250VAC; 1/2HP 125VAC; 3/4HP 250VAC.
Differential is about 60 mbar.
- High rating micro-switch (medium and high vacuum calibration only): 2HP 240VAC, 22 (8)A 240VAC.
Differential is about 90 mbar.
Action: Momentary.
Set point calibration: factory calibrated and sealed, not field adjustable. The value given is that of the opening of the contact when the vacuum becomes greater.
Calibration condition: The contact between COM and NC opens when vacuum pressure goes from atmospheric pressure to requested vacuum set point. When the atmospheric pressure is positive, the contact is closed between COM and NC.
Set point calibration limits: From -2 kPa (-20 mbar, -0.3 PSI) to -90 kPa (-900 mbar, -13 PSI).
Electrical connection: 6.35 × 0.8mm quick connect terminals.
Maximum positive pressure: 300 kPa (3000 mbar, 43.5 PSI).
Maximum vacuum: -90 kPa (-900 mbar, -13 PSI).
Ambient temperature limits: water: 0 to 85°C (32 to 185°F), Air: -10 ~ 85°C (14 to 185°F)
Approval: UL 508
