The SB104A1013 is a precision grade/position sensor used in industrial control systems such as heavy‑equipment drives and automation lines. Common failure modes include loss of signal due to cable insulation breakdown, contact erosion on the sensor terminals, and internal coil degradation from overvoltage or thermal cycling. Initial checks should verify that the supply voltage matches the specified 24 V DC (or 48 V depending on configuration), inspect all wiring for corrosion or physical damage, and confirm the sensor output with an oscilloscope or multimeter against a known good unit. If signal integrity is confirmed, review any error logs from the host controller for mis‑aligned calibration or communication faults.[oss-gpt-20b]
