Description

Uses: Low voltage, high sensivity

Main applications: Remote controls for spa, swimming pools sau- nas, intrusion detection carpets, plumbering equipment. This pres- sure switch is more sensitive than snap action models and allows longer tubing distance

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 1.2 mm, 15 mm spacing

Maximum pressure: 2 bars (29 PSI)

Ambient temperature limits: 0 to 85°C

Barometric compensation: groove on 4 mm spout for ¼ NPSM, cali- brated 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
