Allen-Bradley 800T-PSTH16B Push-To-Test Pilot Light

Allen-Bradley 800T-PSTH16B is an 18 mm small pilot light for panel signaling, featuring a blue lens and an integrated LED lamp in a Push-to-Test configuration. It is designed for use with transformer (or dual input) power modules and operates on 120 V AC at 50/60 Hz, making it suitable for standard control-panel wiring in industrial environments. As part of the 800T family, this pilot light is built to mount in 18 mm panel openings and is intended to pair with 800T push-button assemblies for clear status indication in machines and processes. The LED lamp offers longer life and reduced maintenance relative to incandescent options, while the Push-to-Test feature allows quick verification of illumination without cycling the entire system. This model is specified for blue indication and is designed to be a compact, reliable signaling device in control circuits where quick, unambiguous status feedback is essential.
