Allen-Bradley 800MR-P16B Round Pilot Light Assembly

Allen-Bradley 800MR-P16B Round Pilot Light Assembly is a transformer-type indicator designed for 22.5 mm round control panels, featuring a blue lens to signal machine status clearly in automation equipment. The unit includes a built-in transformer and stab-terminal wiring, and it is rated for 120 V AC operation at 50/60 Hz, making it compatible with standard industrial control circuits. This blue variant is part of the 800MR family of round pilot lights, which fit standard 22.5 mm panel openings and provide a compact status indicator on control panels, PLC interfaces, and machine dashboards. Color options in the 800MR-P16 family include red (P16R), green (P16G), and amber (P16A) variants, with blue delivered by the P16B suffix. The assembly’s stab-terminal connections simplify wiring during panel assembly and maintenance, delivering a reliable visual cue for start/stop, fault, or ready-to-run conditions in industrial systems.
