Barksdale B1X-H22-UL Pressure Switch Class II

The Barksdale B1X-H22-UL Pressure Switch Class II is a rugged explosion‑proof bourdon‑tube switch engineered for hazardous locations, offering UL and CSA approvals and operation at 125/250/480 V for precise, repeatable limit switching in dusty industrial environments. It uses a stainless steel bourdon tube and a 1/2 in. NPT female pressure fitting (P24), with a SPDT snap‑action contact rated up to 10 A at 125/250 VAC and 3 A at 480 VAC. The B1X family also provides hermetically sealed options (AA, CC, HH) for harsher applications, and ATEX certification can be selected in place of hermetic sealing where required. This model is well suited for single‑point control in industrial processes where reliable switching is essential, including chemical processing, mining, and other Class II dust‑hazard environments requiring strict electrical and mechanical performance.
