Siemens 52BL4E2XB Pilot Light Indicator Module

Siemens 52BL4E2XB BlackMax 30 mm pilot light indicator module is a full‑voltage LED indicator designed for panel mounting in industrial control cabinets. This complete metal unit uses a BA9s base with screw terminals and a red plastic lens, and it runs on 120 V AC/DC (full voltage) to illuminate the indicator LED. The 52BL4E2XB features corrosion‑resistant epoxy‑coated housing and threaded mounting for secure panel installation. It carries broad environmental and safety ratings, including NEMA 1, 3, 3R, 4, 4X, 12, and 13, with IP20 and IP66 protection depending on configuration. Operating temperature range is approximately −31 to 158 °F (−35 to 70 °C) with storage from −40 to 185 °F (−40 to 85 °C). Common in control panels and automation equipment for status indication in demanding environments, the BlackMax LED indicator provides a visible status signal in red LED variant as part of Siemens’ 52 Series pilot lights.
