Allen-Bradley 800H-QRAH2B Illuminated Push Button

Allen-Bradley 800H-QRAH2B is a 30.5 mm illuminated momentary push button from Rockwell Automation’s 800H family, engineered for panel mounting with an extended head and guard to help prevent unintended actuation. It uses a full-voltage LED illumination module that accepts 12–130 V AC/DC and emits blue illumination through a blue lens, ensuring clear signaling in control panels and equipment enclosures. The device uses screw-terminal connections and provides a standard 1 NO – 1 NC contact block, suitable for single-acting start/stop signaling in industrial automation. With a Type 4/4X/13 rating, the unit is designed for harsh environments, and the contact blocks offer an electrical design life of up to 1,000,000 cycles at max load, underscoring long-term reliability in demanding applications. The combination of a robust extended head with guard, blue LED illumination, and compact 30.5 mm footprint makes this push button a precise, visible, and durable choice for panel builders requiring a reliable momentary input.
