Industrial 646GZE11 Pressure Temperature Switch

Industrial CCS 646GZE11 Dual-Snap Pressure Switch is a rugged, explosion‑proof sensor designed for hazardous locations, built around CCS’s Dual Snap disc‑spring technology to deliver repeatable actuation in demanding environments. It features a 1/2" NPT stainless‑steel process connection and wetted parts including a polyimide diaphragm with a Viton O‑ring, encapsulated in an IP65/IP66, NEMA 4/4X/7/9/13 package for harsh applications. The 646GZE11 variant covers an operating pressure range of 20 to 150 psi, with a maximum proof pressure of 4500 psi, and it is rated for operation from −40 °F to 186 °F. Electrical ratings for this family typically reach up to 15 A at 125/250 VAC resistive loads, providing ample capacity for control circuits in safety systems. It carries UL and CSA explosion‑proof certifications, plus CE, CRN, and CCC approvals, reflecting its suitability for oil & gas, power generation, chemical processing, and other industrial processes where hazardous‑area sensing is required. Common applications include process control, fluid handling, and safety interlocks in utilities, water treatment, and manufacturing environments, where reliable switching under vibration and shock is essential. The device’s robust construction and certified protection make it a dependable choice for monitoring pressure in demanding, safety‑critical systems.
