Midori Precisions CPP‑45‑14SX is a compact conductive‑plastic potentiometer/angle sensor used in servo drive or motor control loops to provide position feedback. Common failure modes include drift or loss of linearity from wear, shorted track segments due to corrosion, and mechanical breakage of the shaft or housing under vibration. First‑check steps: verify that the supply voltage to the sensor is within spec (typically 5 V), inspect the wiring harness for broken or frayed conductors, and confirm the output signal matches expected resistance changes across the full travel using a multimeter. If an error code is present in the host controller, cross‑reference it with the sensor’s fault codes (e.g., “OUT_OF_RANGE” or “SHORT_TO_GND”).[oss-gpt-20b]
