Allen-Bradley 871P-E13GRR Proximity Switch

Allen-Bradley 871P-E13GRR is an inductive proximity switch in Rockwell Automation’s VersaCube 871P family, designed for non-contact metal sensing in industrial automation and packaged in a rugged, compact housing that suits tight installation envelopes on controls panels, machine frames, and conveyor lines. It generates a discrete switching signal when a metal target enters its nominal sensing zone and is configured for AC operation with an input voltage range of 40–132 VAC, a specification commonly cited in distributor catalogs for this suffix, aligning with legacy 871P devices that support AC control circuits. As part of the VersaCube series, the 871P sensors emphasize modular mounting, robust environmental sealing, and straightforward wiring to PLCs, enabling reliable end-of-travel or presence detection on equipment such as stamping presses, palletizers, and packaging lines where frequent cycle operation and exposure to dust, vibration, and grime are expected. Because the exact electrical and mechanical configuration can vary by revision (for example related suffixes such as -R3 in other 871P models), the best practice is to consult the official Allen-Bradley 871P data sheet and distributor specifications for this exact suffix to confirm any output type, response characteristics, and mounting dimensions before integration.
