Ashcroft’s (USA) A-Series pressure switches are designed for tough OEM and industrial applications requiring a durable, high-quality miniature switch. Available with explosion-proof and watertight enclosures, the stainless steel A-Series pressure switch features a refined piston actuator that can be ranged up to 2000 psi while enduring a working pressure of 5000 psi. Small dimensions, a choice of connections and a field adjustable set point make the A-Series pressure switch easy to configure and install in nearly any alarm, shutdown or control application.
