Slow action contact miniature air switches for printed circuit boards
Uses: Low voltage, high sensivity
Main applications: Electronic printed circuits and remote controls for spa, swimming pools and saunas. This pressure switch is more sensible than snap action models and allows longer tubing distance

Uses: Low voltage, high sensivity

Membranes: EPDM, dia 22 mm. Silicone or NBR on request
Fluid: air
Fitting: Plastic spout for 1/8(3mm) or 1/16(1.5mm) ID flexible plastic tubing maximum hardness 70 shore A
Pressure: positive
Housing: PA66, UL94 VO and ABS
Contact: single pole normally open, slow make.
Electrical rating:
- Silver contact: max 1A 250V
- Gold plated contact: max 100 mA, 24V
Action: momentary, close on pressure impulse.
Set point calibration: 50mbar, factory calibrated and sealed, not field adjustable. Other values on request
Electrical connection: printed circuit terminal, dia 1 mm, 12.7 mm spacing or dia 1.2mm, 15mm spacing
Maximum pressure: 2 bars (29 PSI)
Ambient temperature limits: 0 to 85°C
Barometric compensation: groove on 4 mm spout for ¼ NPSM, calibrated orifice on 9/16-18
Caution: This compensation is skipped if using ¼ thread for pressure connection
Mounting fittings: ¼” NPSM or 9/16-18 (2 possible flat positions)
Switch operation: Operates on a sealed pressure air displacement. Do not use pressure transmitters with air input to avoid pumping action.
Use air transmitters with enough air volume to achieve minimum operating pressure.
Caution: too long connecting tubing and/or too small pressure transmitter will not operate the air switch or will operate it with a momentary action.
Accessories: shipped with plastic nut. Maximum tightening torque with plastic nut is 0.08mkg (0.8Nm).
Recommended value: 0.5 Nm . Stainless steel nut or tube securing nut (*) on request
