The APW299D-A-120V is a 22mm dome-style illuminated pilot light designed for NEMA 4X and IP65 watertight/oiltight panel applications. This unit features a 120V AC LED lamp with an integrated step-down transformer that reduces voltage to 6V for the LED circuit, providing reliable visual indication in industrial control systems. The pilot light incorporates a corrosion-resistant octagonal chrome-plated locking bezel, amber-colored lens, and snap-on contact blocks rated for 10A at 600V with self-cleaning silver contacts. The LED lamp draws a maximum of 10mA at 120V AC, ensuring low power consumption and extended operational life. With its modular construction, large M10×5 screw terminals with captive semis plate, and fracture-resistant nylon body, the APW299D-A-120V is ideal for machinery control panels, process monitoring, and status indication in harsh industrial environments.
