Barksdale D2X-H18-UL Pressure Switch UL Listed

The Barksdale D2X-H18-UL Pressure Switch is an explosion‑proof diaphragm switch from Barksdale’s D2X family, built for hazardous locations and UL Listed for Class I (B, C, D) and Class II (E, F, G) environments. The unit is rated for 125–600 VAC operation and has a nominal actuation pressure of 60 psi, with housed configurations designed for rugged duty in demanding industrial settings. The D2X‑H18‑UL uses a SPDT snap‑action electrical contact within a sealed enclosure to provide precise, reliable switching in challenging conditions. When used with chemical protectors, the actuation value can shift by roughly 50%, so verify the expected setpoint in your application with the manufacturer documentation or datasheet.
