Siemens 52PE4E2 Red Indicator Pilot Light ACDC

Siemens 52PE4E2 is a red LED indicator pilot light designed for 30 mm 52-series control panels. It operates at 120 V, delivering a full‑voltage signaling solution for panel‑mounted status indication in industrial equipment and control cabinets. As the LED variant of Siemens’ 52-series pilot devices, the 52PE4E2 offers a compact, durable indicator with a red lens that stays visible across factory floors. Installation uses the standard 52-series panel footprint, allowing direct replacement in compatible enclosures and with other 52-series indicators or pushbuttons, which helps simplify wiring and reduces inventory variety. The LED light source delivers bright, steady illumination with long life, and its red color ensures clear state signaling even in bright environments. Typical applications include signaling the ON state of machines, indicating ready status on control panels, or marking emergency shutdown circuits in manufacturing lines. The part number 52PE4E2 identifies Siemens’ full-voltage LED indicator light in the 52 family, aligning with other 52PL/52PA pilot devices that share mounting and electrical characteristics, ensuring consistent operation across your panel assemblies.
