Allen-Bradley 802M-DZJ7 Limit Switch

The Allen-Bradley 802M-DZJ7 is a factory-sealed, pre-wired limit switch delivered as a complete unit, built for harsh industrial environments where reliability matters. It features a top-push roller actuator and two independent DC circuits housed in a standard body, enabling separate control and safety wiring within the same device. The electrical interface is a 4-pin micro-type receptacle wired to the J7 configuration, paired with DC quick-disconnect terminals for compact, plug-in panel connections. As part of the 802M family, this DZJ7 variant provides pre-wired leads and factory sealing to reduce on-site wiring and assembly time while maintaining consistent operation under frequent actuation. Typical applications include limit sensing on conveyors and presses, safety interlock subassemblies, and position feedback in automated lines where reliable actuation and straightforward wiring are essential. The model is commonly used with 24V DC control circuits, delivering a compact, standard-body form factor that fits a wide range of control panel layouts and equipment architectures.
