Honeywell’s Pressure Switches are durable, reliable electromechanical gage pressure on/off switches consisting of high, medium and low pressure options. Available with either single pole single throw (SPST) normally open or normally closed circuitry, or single pole double throw (SPDT) circuitry.

IP67 environmental sealing and high proof pressure and burst pressure ratings for use in many rugged applications requiring making or breaking of an electrical connection in response to a pressure change of the system media.

Pressure switching set point range:

- Honeywell’s High Pressure: HP Series and HE Series are factory set 100 psi to 4500
- NEW Medium Pressure: Honeywell ME Series are factory set or field adjustable 25
psi to 350 psi
- Low Pressure: LP Series and LE Series are factory set or field adjustable 3.5 psi to
150 psi

- Life cycle rating: Up to 2 million cycles depending on series
- Burst pressure: Varies by series; from 1,250 psi up to 20,000 psi (see datasheet)
- IP67 sealing rating
- Operating temperature range -40 °C to 120 °C [-40 °F to 248 °F]
- Hysteresis option (HP, HE, LP Series)
- Variety of pressure ports and electrical terminations
- Switching point accuracy up to ±2 %
