Weko KD-NR:HDM 5E.110.1481/01 NR:140.172485/23 0044401 Sensor

Weko KD‑NR:HDM 5E.110.1481/01 is a high‑precision optical sensor module used in industrial brake detection and position monitoring systems. Common failure modes for this class of sensors include photodiode degradation from dust or vibration, LED driver burnout due to overvoltage, and solder joint fatigue on the connector pins. Begin diagnostics by verifying the supply voltage matches the specified 12 V ±10 %, inspecting the optical path for contamination or misalignment, and checking the I/O signals with an oscilloscope for proper waveform shape and amplitude.[oss-gpt-20b]
