Allen-Bradley 800T-Q20 Pilot Light

Allen-Bradley 800T-Q20 Pilot Light is a 30.5 mm Type 4/13 indicator lamp designed for use with the 800T family of Allen-Bradley 30 mm pushbuttons. It provides direct full-voltage illumination for status indication in industrial panels and equipment, powered from 240 V AC or DC and employing an incandescent lamp. As part of Rockwell Automation’s 800T illumination module lineup, the Q20 variant fits into standard 800T housings to convey machine state—on, off, or fault conditions—within control circuits and panel assemblies. Color variants exist under the 800T-Q20 family, including amber (Q20A) and green (Q20G), enabling color-coding of signals in multi-indicator installations. The combination of 30.5 mm footprint, 240 V AC/DC input, and incandescent illumination makes it a straightforward, drop-in indicator for 800T pushbutton assemblies in a wide range of manufacturing and process environments.
