The XCKVR54D1H29 limit switch from Yueqing Huilong is engineered for high - reliability applications requiring precise position detection. This model features a stainless - steel body with an IP67 protection rating, making it suitable for washdown environments in food and beverage industries. Its unique double - break contact design (2NO + 2NC) provides redundant switching for safety - critical systems, while the gold - plated contacts ensure low resistance (≤30mΩ). The switch supports a wide operating temperature range (- 25℃ to + 80℃) and withstands 1000V dielectric strength. With a mechanical life of 20 million cycles, it is ideal for continuous - operation machinery like bottling lines, printing presses, and automotive conveyors. The XCKVR54D1H29 also includes a self - cleaning contact mechanism, reducing maintenance needs in dusty or oily environments.
