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
