Series 4000 pressure switches convert pressure changes into electrical outputs via an elastomeric diaphragm actuating a snap-action switch with field-adjustable set points. Pressure ranges from 2" W.C. (500 Pa) to 11 PSI (76 kPa) are available, with SPST or SPDT switching options and 1/4" male quick-connect electrical terminals. The switches are rated for 25 A at 250 VAC, operate reliably from 32°F to 190°F (0°C to 88°C), and offer 100,000 cycle life under full electrical, mechanical, and thermal loads. Constructed with an injection-molded switch pan and available with various pressure fittings including NPT and compression types, the switches provide overpressure protection and are UL Recognized and CE approved for use as operating, limit, or safety controls.
Series 4000 pressure switches convert a pressure signal to an electrical output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. The Series 4000 features cost effective, snap-acting electrical switches and field adjustable set points with a visual scale for easy set point selection. Pressure ranges as low as 2" (500 Pa) Water Column (W.C.)* up to 11 PSI (76 kPa) are available. Series 4000 switches assure control stability through wide and variable temperature and humidity conditions and assure uninterrupted service under extreme shock and vibration. As with all Tecmark® products, series 4000 switches provide superior performance and 100,000 cycle life under full mechanical, electrical and thermal loads.
