Ashcroft Inc. B420T-XTA07 Pressure Control Switch

Ashcroft B420T-XTA07 Pressure Control Switch is an industrially rated device that monitors system pressure and opens or closes electrical contacts when the pressure reaches a user-defined threshold. Designed for rugged, continuous operation, this model is part of Ashcroft’s B-Series family of pressure switches, built to withstand demanding industrial environments and provide repeatable performance across a range of service conditions.

As a B-Series pressure switch, the B420T-XTA07 combines a sensing element with snap-action switching to deliver reliable control signals for process equipment, pumps, and safety interlocks. The XTA07 suffix denotes a specific variant configuration within the line, defining its intended electrical and mechanical fitment within Ashcroft's catalog. This configuration supports integration into standard control circuits where automatic pressure-based switching is required.

Applications typically include hydraulic and pneumatic systems, process instrumentation, and safety circuits where maintaining or limiting pressure is critical. The compact form factor and Ashcroft pedigree emphasize durability and repeatability, enabling operators to deploy the B420T-XTA07 in environments that demand dependable pressure control without sacrificing response clarity or long-term stability.
