Slow action contact miniature vacuum switches for printed circuit
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.

Description
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 or metal
Pressure: negative (Vacuum)
Housing: PA66, UL94 VO
Contact: single pole normally open or normally close at atmospheric pressure, slow make.
Electrical rating:
- Silver contact: max 1A 250V
- Gold plated contact: max 100 mA, 24V
Action: momentary, close or open 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 (30 PSI)
Maximum vacuum: minus 500 mbar (relative pressure)
Ambient temperature limits: 0 to 85°C
