使用场景 APPLICATIONS

1 Industrial manufacturing lines: Detect presence/absence of metal workpieces (e.g., automotive parts, electronic components) on conveyor belts

2 Packaging machinery: Verify presence of metal packaging materials or components before sealing/packaging

3 Assembly lines: Ensure correct placement of metal parts (bolts, nuts, panels) during assembly processes

4 Material handling systems: Confirm metal pallets/containers are in position for loading/unloading operations

5 Machine tools: Detect tool presence or workpiece position in CNC machines, lathes, or milling equipment

6 Automated sorting systems: Identify metal objects for classification in logistics or production facilities

注意事项 PRECAUTIONS

1 Safety Precautions

2 Power supply: Do not apply AC voltage to DC models; avoid excessive voltage beyond rated range

3 Load handling: Prevent load short-circuit; ensure correct polarity for short-circuit protection to function

4 Wiring: Correctly wire sensor and load; do not operate without proper load connected

5 Environment: Do not use in flammable/explosive gas environments; do not disassemble, repair, or modify the sensor

6 Correct Use

7 Power reset: Allow 100ms after power-on for sensor to be ready; supply power to sensor before load if using separate power sources

8 Surrounding metal: Maintain specified clearances from surrounding metal (refer to engineering data tables)

9 Mutual interference: Keep minimum distances (A/B values as per specs) when installing multiple sensors face-to-face or side-by-side

10 Wiring: Avoid routing cables near high-tension lines; use metal conduit if needed. Cable extension max200m; tractive force ≤50N

11 Mounting: Do not strike with hammer; do not over-tighten nuts (use washer; M18 torque ≤70N·m)

12 Maintenance: Periodically check mounting position, wiring connections, dust/metal powder accumulation, ambient temperature, and indicator light

13 Environment: Not suitable for underwater/outdoor/rain use; avoid exposure to strong acid/alkaline chemical gases

14 Load with inrush current: Use relay between sensor and loads like lamps/motors to prevent damage
