Allen-Bradley 802XR-A3C7 Limit Switch

Allen-Bradley 802XR-A3C7 is a sealed hazardous-location limit switch from the 802XR family, designed for reliable end-of-travel signaling in environments requiring protection for hazardous locations (NEMA Type 7 and 9). It features a full-head lever actuator (rotary lever) and provides two circuits: one normally open and one normally closed, with snap-acting, spring-return contacts. The unit uses a single head-and-body construction and includes conduit entry of 1/2 in. NPT for wiring. It is rated for operation from −29 °C to 121 °C and is specified for clockwise operation only. The A3C7 variant designation corresponds to this lever-type configuration with standard contact arrangements, enabling straightforward signaling for safety interlocks or control circuits in harsh environments. With two discrete circuits housed in a sealed package, it supports multiple signaling paths from a single device while maintaining protection against dust and moisture when installed per its ratings.
