使用场景 APPLICATIONS

1 Industrial automation lines: Detecting presence/absence of metal workpieces on conveyor belts

2 Assembly equipment: Positioning metal components (bolts, nuts, parts) during assembly processes

3 Material handling systems: Identifying metal packages/containers in logistics and warehousing

4 Packaging machinery: Sensing metal parts in packaging materials to ensure proper sealing

5 Robotic applications: Assisting robotic arms in part picking/placement by detecting component positions

6 Machine tools: Monitoring tool change status or workpiece presence in CNC machining operations

7 Automotive production: Component detection in engine or chassis assembly lines

注意事项 PRECAUTIONS

1 Power supply: Do not apply voltage beyond 10-32VDC; avoid AC voltage on DC models

2 Load handling: Prevent short-circuiting the output load; use a relay for loads with large inrush current (e.g., lamps, motors)

3 Wiring: Ensure correct wiring (brown=+V, black=output, blue=0V for NPN models); do not operate without a load

4 Mounting: Do not hit the sensor with a hammer; tighten the nut with torque ≤30N·m (use a washer); maintain clearance from surrounding metal

5 Multiple sensors: Keep minimum distance between sensors to avoid mutual interference (refer to engineering data for specific distances)

6 Environment: Avoid flammable/explosive gases, underwater exposure, and strong acid/alkaline environments; use metal conduit if near high-tension lines

7 Maintenance: Periodically check mounting position, wiring integrity, metal dust accumulation, indicator operation, and ambient temperature

8 Cable: Extend cable length to ≤200m; do not exceed tractive force of50N
