Ashcroft PPAN4HB25 Pressure Switch is an industrial pressure-sensing device designed to actuate a control circuit when the monitored pressure reaches its specified range. It is specified with a range of 15 psi and a proof pressure of 500 psi, meaning the switch can withstand up to 500 psi without permanent deformation while operating within its 15 psi switching range. The PPAN4HB25 model is part of Ashcroft’s line of pressure switches, delivering robust construction and reliable actuation for standard process and equipment-monitoring tasks.
