5 Response & target: Standard target is 24×24×1mm mild steel ST37, response frequency up to800Hz (under specified conditions)

6 Environmental resistance: IP67 protection rating (dust and water resistant), operating temperature range of -40°C to70°C (no icing/condensation), storage temperature range of-40°C to85°C

7 Mechanical durability: Vibration resistance (10-55Hz,1.5mm double amplitude for2hours each in X/Y/Z directions), shock resistance (1000m/s² for10times each in X/Y/Z directions)

8 Construction details: Case made of brass-nickel plated material, sensing surface of PBT, clamping nut of brass-nickel plated, M12 4-pin connector for quick installation

9 Additional features: Modular construction supports customization, built-in yellow LED operation indicator for real-time status monitoring

使用场景 APPLICATIONS

1 Industrial assembly lines: Detect presence/position of metal parts (e.g., screws, gears, electronic components) to trigger assembly steps or stop operations if parts are missing

2 Conveyor belt systems: Monitor presence of packages or materials on belts to control speed, sort items, or prevent jams

3 Packaging machinery: Verify correct positioning of metal cans, caps, or packaging materials before sealing/labeling

4 Machine tools: Detect tool position or workpiece presence to ensure safe and accurate machining

5 Automotive manufacturing: Check presence of automotive parts (e.g., bolts, panels) in production lines for quality control

6 Robotics: Assist robotic arms in detecting workpiece presence/position for precise picking/placement tasks

7 Printing equipment: Detect paper or metal foil presence to avoid blank printing or machine damage

8 Food processing (dry/semi-wet environments): Detect metal containers or parts in processing lines (avoid direct contact with corrosive substances)

9 Material handling: Ensure proper loading/unloading of metal items in warehouses or distribution centers

注意事项 PRECAUTIONS

1 Safety Precautions:

2 Do not apply AC voltage (100-240VAC) to DC models; avoid excessive voltage to prevent sensor damage

3 Avoid load short circuits (sensor has short-circuit protection, but correct polarity/voltage range is required)

4 Do not use in flammable/explosive gas environments

5 Do not disassemble, repair, or modify the sensor

6 Correct Use:

7 Allow 100ms power reset time after turning on; supply power to sensor before load if separate sources are used

8 Maintain specified clearances from surrounding metal to avoid malfunction

9 Turn off load before powering off sensor to prevent pulse signal output

10 Use insulated DC power transformer (not auto-transformer)

11 Maintain minimum distances between multiple sensors (non-shielded M12 short barrel:120mm face-to-face,100mm side-by-side)

12 Wiring:

13 Keep cables away from high-tension lines; use metal conduit if needed

14 Extend cables up to200m max; do not exceed50N tractive force

15 Mounting:

16 Do not strike with hammer during installation (risk of damage/water resistance loss)

17 Use washer with clamping nut; max torque for M12:30N·m

18 Maintenance:

19 Periodically check mounting position, wiring, metal dust, ambient temp, and LED status

20 Do not use underwater/outdoors in rain (IP67 is water-resistant, not waterproof)

21 Avoid strong alkaline/acid gases (e.g., nitric acid) to prevent corrosion

22 Use relay for loads with large inrush current (lamps/motors)
