Allen-Bradley 800EM-PL1 Optical Indicator Light

Allen-Bradley 800EM-PL1 is an optical indicator light (pilot light) designed to accompany the 800EM family of push-button and indicator devices from Rockwell Automation. The PL1 variant is the white version, configured to emit a high-visibility indication on control panels with a white lens appearance that matches other white-status indicators in 800-series assemblies. This unit is part of the older 800E/800F/800FC/800M family, and Rockwell documents the 800EM line as an obsolescent signaling component within the broader 800-series lineup. Typical applications include panel signaling to convey machine state or process status when integrated with 800-series operators. The 800EM-PL1 is manufactured by Allen-Bradley (Rockwell Automation) and is commonly available through authorized distributors such as MRO Supply and Radwell, which list the 800EM-PL1 Optic Pilot Light White as a standalone accessory for 800-series panels. In related literature, 800EM front elements are described as metal constructions, reinforcing their use in rugged, panel-mount signaling roles within industrial environments. This description reflects verified, cataloged facts about the product: a dedicated optical indicator light for the 800-series signaling ecosystem, color-matched to white indicators, and designed to complement the 800-series operator lineup.
