The APW299D-G-120V is a 22mm dome-style pilot light from IDEC's TW Series designed for industrial signaling and status indication applications. This unit features LED illumination operating at 120V AC full voltage (lamp determines voltage), eliminating the need for a step-down transformer, and includes a green lens for clear visual indication. The pilot light is constructed with a corrosion-resistant octagonal chrome-plated locking bezel and fracture-resistant nylon body, providing durability in harsh industrial environments. The LED contains an integrated current-limiting resistor and protection diode for reliable long-term operation. With its modular construction, NEMA 4X and IP65 watertight/oiltight panel rating, and large M10×5 screw terminals with captive semi-plate, this pilot light is ideal for control panels, machinery status displays, and process monitoring systems requiring robust, maintenance-free illumination.
