The KPH300 is an excellent choice for pressure switching applications that require a reliable solution and low cost. The KPH300 utilizes the proven diaphragm or piston sensing technology depending on the measuring range chosen. The setpoint and hystersis are field adjustable via a 2 mm hex nut adjuster protected from the elements beneath the DIN 43650 electrical connector. The switch can also be factory set at the setpoint you specify. The SPDT micro-switch contacts are silver-plated for extended service life. The combination of high reliability design and low cost makes the KPH300 an excellent choice for OEM and end user applications alike.
