DIMENSIONS
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: Plastic.
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: printed circuit terminal, dia 1.2 mm, 15 mm spacing.
Maximum pressure: 2 bars (29 PSI).
Maximum vacuum: minus 500 mbar (relative pressure).
Ambient temperature limits: 0 to 85°C.
