Weko HDM 5E.110.1421/U Control Module

Weko HDM 5E.110.1421/U is an industrial photoelectric sensor used in line‑following or presence detection applications. Common failure modes include optical misalignment, contamination of the lens or emitter/receiver surfaces, and power supply ripple that can trigger false triggers; internal PCB damage from overvoltage or electrostatic discharge is also noted. First‑check diagnostics: verify 11–30 VDC input voltage and continuity to ground, inspect the sensor housing for dust or scratches on the optical path, and review any error codes or indicator LEDs for abnormal status.[oss-gpt-20b]
