Barksdale B2X-H12-UL Hazardous Location Pressure Switch

The Barksdale B2X-H12-UL is an explosion‑proof bourdon‑tube pressure switch for hazardous locations, rated for pressures up to 1,800 psi and housed in a 4.5‑inch wire box. It belongs to Barksdale’s B1X/B2X family and is UL/CSA listed for Class I, Groups B, C, & D, with Class II Groups E, F, & G, with ATEX options available in some configurations. The pressure port is a 1/4‑inch NPT female, and B2X models use 3/4‑inch NPT conduit connections. The internal mechanism is a snap‑action SPDT switch, with electrical ratings commonly 10 A at 125/250 VAC and 3 A at 480 VAC, suitable for control circuits in hazardous environments. Enclosures provide NEMA 4, 7, and 9 protection, ensuring reliable operation in demanding industrial settings. This model is designed to monitor hydraulic or pneumatic pressures where hazardous‑location compliance and precise actuation are required, offering a straightforward electrical interface for safety interlocks or process control loops.
