Product Self-Inspection Steps

1. Detect any deviation, slack, or skew in the installation position of the object and proximity sensor, as well as any wiring or connection issues.
2. Check for adhesion or accumulation of metal dust.
3. Ensure normal usage under temperature and environmental conditions.
4. Verify the display lamp type for abnormal flashing.

During inspection, avoid self-disassembly and repair. Use a portable detector to investigate the sensor's operating state for easy fault detection and repair.

Regularly check the photoelectric sensor to maintain long-term stability. Stock replacement sensors to quickly address any issues without disrupting sensor usage.
