Siemens 52PL4G2 Transformer Pilot Light

Siemens 52PL4G2 is a 30 mm panel-mount pilot light with an integrated transformer, built for industrial control panels requiring a visible red status indicator. It uses a red concentric-ring lens over a BA9s incandescent lamp and is housed in a chrome metal bezel with a plastic lens assembly for rugged panel mounting. Wiring is via screw terminals, and the unit is designed for 120 V AC operation. Part of the Siemens Command 52 family, the 52PL4G2 is suitable for NEMA 1/3/3R/4/4X/12/13 enclosures and can operate from -35 to 70 degrees Celsius, making it appropriate for harsh industrial environments. Typical applications include signaling and status indication on machines, conveyors, presses, and power-distribution panels where a clear red indicator is required.
