Main applications :
Direct actuating of pumps and blowers in whirlpool baths, hot tubs, jacuzzis and swimming pools, sink erasers, garbage disposers, medical equipment, plumbing or home appliances used with risks of water splashing. Resist to spas and swimming pools ozone concentration.
They feature in standard a patented barometric and thermometric compensation, anti-vibration locking, and are protected against tampering. Compared to the old ZP model, although in a smaller footprint, the design of the mechanical assembly and the diaphragm greatly increases the length of the usable connecting tube.
Technical features :
Fluid: Air only
Pressure port connection: Plastic spout, for 1/8" (3mm) ID flexible plastic tubing.
Maximum PVC tube hardness 70 shore A
Membrane: Silicone, 22mm diameter.
Housing: PA66
Contact: Snap action, SPNO.
Electrical rating:
- Standard rating micro-switch: 16A 125/250VAC; 1/2HP 125VAC; 3/4HP 250VAC
- On request: up to 22A, 2HP 250VAC
Action (2 styles of action are possible):
- Momentary: the contact switches when under pressure, and returns to its original position when there is no more pressure.
- Latching: a first pressure pulse switches the contact, which remains in this position, and only returns to its initial position with a second pressure pulse.
Electrical connection: 6.35 × 0.8mm quick connect terminals
Maximum operating pressure: 120 kPa (1200 mbar, 17 PSI)
Ambient temperature limits: Air: -10 ~ 85°C (14 to 185°F).
Barometric compensation: Calibrated flow leak orifice inside the pressure chamber
Mounting fittings: ¼" NPSM with 2 flats at 11 mm distance on thread, for installation through a board.
Switch operation: Operates on a sealed pressure air displacement, with patented calibrated micro-leak providing barometric and temperature compensation.
Caution: Use air transmitters with enough air volume to achieve minimum operating pressure. Too long connection tubes and/or too small pressure transmitter will not operate the air switch or will operate it with a momentary action.
Accessories, in option or available as spare parts: ABS plastic nut (Maximum tightening torque 1.5 Nm) and tube securing nut (Maximum tightening torque 2 Nm).
