Pressure Switch for Industrial Control
The Ashcroft APAN41H012LB021000#-NSR is a pressure switch built for process and machine applications. It suits engineers and maintenance teams who need reliable actuation in hydraulic or pneumatic systems. The unit operates across a 100 to 1000 psi range with a 316L stainless steel housing. It is compatible with air and liquids in standard industrial environments.
Capacity and Headroom
The switch handles AC loads up to 5 A at 125 or 250 V and DC loads up to 5 A resistive or 3 A inductive at 28 V. A burst pressure of 30000 psi provides a wide safety margin above the working range. The SPDT contact form (1NO/1NC) supports simple on/off or alarm circuits. The NEMA 6 and IP67 ratings confirm protection against water ingress and dust in wash-down areas.
Build Integration
Electrical connection uses 3-18 AWG PVC insulated wire leads measuring 12 inches for direct wiring into panels or junction boxes. The 1/4 inch MNPT process connection threads into standard ports without adapters. Wetted parts are 316 stainless steel and Buna-N for fluid compatibility. The compact housing frees space inside crowded enclosures while the high burst rating reduces the need for external over-pressure protection.

Questions about this item
Will the 1/4 in MNPT process connection thread directly into my existing 1/4 in NPT port?
Yes, the 1/4 in MNPT connection is designed to thread into a standard 1/4 in NPT female port.
How can I verify the switch actuates correctly across the 100 to 1000 psi range after installation?
Apply known pressure within the 100 to 1000 psi range and confirm the SPDT contacts change state using a multimeter on the 12 in wire leads.
Does the box include the 3-18 AWG PVC insulated 12 in wire leads or must I supply my own wiring?
The 3-18 AWG PVC insulated 12 in wire leads are factory attached to the switch and included in the box.
