Allen-Bradley 802A-E37M3-S7 Limit Switch

Allen-Bradley 802A-E37M3-S7 is an industrial limit switch used for end-of-travel sensing in automation equipment. It is rated to switch up to 10 amps at voltages up to 500 V, making it suitable for control circuits that require reliable switching at relatively high line voltages. The model is part of the 802A family, designed to deliver discrete electrical signals when a moving part reaches a predefined limit, enabling machine control. Typical applications include signaling to programmable logic controllers for cycle control, triggering safety interlocks, or stopping a machine at a defined position on conveyors, presses, and similar equipment. Engineers commonly pair this type of switch with Allen-Bradley control circuits and compatible wiring to provide dependable limit-switch feedback in automated lines, contributing to predictable machine performance and straightforward wiring schematics.
