Allen-Bradley 800MB-CQ24G Square Pilot Light

Allen-Bradley 800MB-CQ24G is a 22.5 mm square pilot light with a green lens, designed for backlit indication in control panels and automation equipment. This incandescent, full-voltage unit operates on 24 VAC or 24 VDC and is part of the 800MB family of panel-mounted indicator lights. The compact 22.5 mm package fits standard Allen-Bradley 22 mm operator enclosures, providing a visible status signal in dim environments such as machine dashboards, control panels, and safety interlocks. Typical applications include signaling machine state, start/stop indicators, and panel-level status lights in industrial automation, where direct 24 V AC/DC drive from common control circuits simplifies integration with PLCs and relays. The green lamp offers clear differentiation from other colors in multi-indicator applications, and the backlit design enhances visibility in enclosed or mounted panels. The 800MB line also includes color variants and related test or LED options; verify you select the 24V AC/DC incandescent version (CQ24G) to ensure voltage and color compatibility with your control system.
