Operating temperature ... −40 to 121 °C (−40 to 250 °F)

Actuation pressure at 21 ± 3 °C (70 ± 5 °F) ... 293 ± 35 kPa (42 ± 5 psi)

Actuation pressure at 100 ± 3 °C (212 ± 5 °F) ... 276 ± 28 kPa (40 ± 4 psi)

Minimum deactuation pressure at operating temperature ... 179 kPa (26 psi)

Contact position ... Normally closed below deactuation pressure

Note: Mount the pressure switch group below horizontal in order to provide drainage for condensation. Mount the pressure switch group to a minimum of 600 mm (23.6 inch) from electrical components such as starting motors, solenoids and power cables that generate a large magnetic field.
