product presentation

Main applications :
These miniature slow-action pressure switches greatly outperform snap action models because they have high sensivity and low differential. They are designed to be incorporated into a printed circuit board which provides power relay. Their reduced thickness of 15mm favors installation in applications requiring a small footprint.

Technical features : Fluid: Air or water
Pressure port connection: ⅛” BSPT, ⅛” NPT or side spout
- For ⅛” (3mm) ID flexible plastic tubing
- For 1/16” (1.5 mm) ID flexible plastic tubing
Maximum PVC tube hardness 70 shore A
Membrane: Silicone, 22mm diameter.

Housing: PA66
Contact: Slow make and break, contact is closed at atmospheric pressure and open when vacuum increases. Electrical rating: 1A 250VAC resistive (silver contacts), 10mA 24VDC (5 microns gold plated contacts). We recommend gold plated contacts for low voltage and low current circuits to avoid the increase in contact resistance that appears on silver contacts as they oxidize.

Action: Momentary
