9 Durable materials: Sensing surface made of PBT, clamping nut brass-nickel plated

使用场景 APPLICATIONS

1 Industrial assembly lines: Detect presence/absence of metal components (e.g., screws, gears, panels) to ensure correct assembly sequences

2 Packaging machinery: Count metal items passing through the line or detect metal inserts in packaging materials

3 Material handling systems: Position metal workpieces on conveyors or robotic arms for precise picking and placing operations

4 Automotive manufacturing: Identify metal parts (e.g., body parts, bolts) to trigger subsequent production processes

5 Machine tools: Detect tool presence or workpiece position to prevent collisions and ensure accurate machining

注意事项 PRECAUTIONS

1 Power supply: Do not apply AC voltage to DC models; avoid voltage exceeding the rated range (10-32VDC)

2 Wiring: Keep sensor cables away from high-tension lines; use independent metal conduit if necessary to prevent interference; do not extend cables beyond 200m; do not apply tractive force over 50N to cables

3 Mounting: Do not strike the sensor with a hammer during installation; tighten the clamping nut with appropriate torque (30N·m for M12) using a washer; maintain required clearances from surrounding metal to avoid mutual interference

4 Maintenance: Regularly check for loose wiring, sensor displacement, and metal dust accumulation; do not disassemble or modify the sensor

5 Environment: Do not use underwater or in flammable/explosive gas environments; avoid exposure to strong alkaline or acid gases; when using at -40°C to-25°C with 30-32VDC, limit load current to max100mA

6 Load: Do not short-circuit the load; connect loads with large inrush current (e.g., lamps, motors) via a relay
