Ashcroft B464S XLEMH Pressure Switch

Ashcroft B464S pressure switch is a rugged electro‑mechanical device that opens or closes electrical contacts when a preset pressure is reached, providing a reliable control, shutdown, or alarm signal in industrial systems. It is used across process and equipment applications to monitor pressure in hydraulic and pneumatic circuits and to trigger automated responses. Public listings tie the B464S to a 30 psi setpoint and a 480 VAC electrical rating, indicating suitability for standard control circuits in harsh industrial environments. The B464S family includes variants such as XFS, which shows Ashcroft’s practice of using model codes to denote different contact configurations and diaphragms. Within Ashcroft’s broader B-series line, pressure switches are designed for robust service in demanding environments, with a variety of enclosure ratings and switch elements to match media and duty. For precise configuration details, consult the supplier’s datasheet for the exact actuator, process connection, and electrical wiring of the specific variant you’re using.
