Allen-Bradley 855E-LL12R Indicator Light

Allen-Bradley 855E-LL12R is a red LED indicator lamp designed for 50 mm stack-light assemblies and used as the signaling element in socket-mounted modules. The device operates at 12V AC/DC full voltage and measures 46 mm in length with a 32.8 mm diameter, offering an average nominal lifespan of 100,000 hours to minimize maintenance in demanding environments. As an accessory for socket-mounted 50 mm signaling towers, the 855E-LL12R provides a bright status indication in industrial control panels and pairs with various upper-module configurations, including top modules that are sound or light-with-sound variants. No cap is required when the top module is a sound module or a light-with-sound module, simplifying installation in certain stacking configurations.
