3 Electrical specifications: DC 3-wire NPN open collector output; operating voltage range 10-32VDC (rated 12-24VDC, ripple p-p ≤10%); current consumption ≤10mA; load current ≤200mA (max 32VDC); residual voltage ≤2V (200mA load, 2m cable)

4 Construction: Brass-nickel plated case and clamping nuts; PBT sensing surface; pre-wired PVC cable (length:2m, 4mm diameter, 3 conductors of 0.3mm² cross-section)

5 Protection & compliance: Equipped with output reverse polarity, power reverse polarity, surge suppressor, and short-circuit protection; IP67 rating (IEC60529); EMC compliant (EN60947-5-2)

6 Environmental resistance: Operating temperature -40°C to 70°C, storage temperature -40°C to85°C (no icing/condensation); vibration resistance (10-55Hz,1.5mm double amplitude,2h each X/Y/Z); shock resistance (1000m/s²,10 times each X/Y/Z)

7 Indicator: Yellow LED operation indicator to show working status

使用场景 APPLICATIONS

This proximity sensor is widely applicable in industrial automation scenarios requiring non-contact metal detection:

1 Automated assembly lines: Detecting presence/absence of metal workpieces (e.g., automotive parts, electronic components) to ensure correct positioning

2 Conveyor systems: Counting metal items passing by or triggering stop signals when a metal object reaches a specific position

3 Machine tools: Positioning metal parts for precise machining operations or verifying tool presence

4 Packaging machinery: Checking if metal packaging components (e.g., cans, caps) are correctly placed before sealing

5 Material handling: Identifying metal pallets/containers in warehouse automation to guide robotic sorting or stacking

6 Robotics: Sensing metal targets to initiate or stop robotic arm movements (e.g., picking up metal parts)

注意事项 PRECAUTIONS

To ensure safe and stable operation, follow these precautions:

Safety Precautions:

1 Power supply: Do not apply AC voltage (100-240V) to DC models; avoid excessive voltage beyond the rated range (10-32VDC)

2 Load handling: Do not short-circuit the load; always connect a proper load (no-load operation may damage internal elements)

3 Environment: Do not expose to flammable/explosive gases; do not disassemble, repair, or modify the product

Correct Use:

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

2 Mutual interference: Maintain minimum distances when installing multiple sensors (M18 non-shielded short barrel: 200mm face-to-face,120mm side-by-side)

3 Surrounding metal: Keep required clearances when mounting in metal panels (non-shielded M18 short barrel:22mm from adjacent metal)

4 Wiring: Avoid high-tension lines; use independent metal conduit if near power lines. Do not extend cables beyond200m; tractive force limit is50N

5 Mounting: Do not hit with a hammer; tighten nuts to70N·m (M18) with a washer

6 Maintenance: Periodically check mounting, wiring, clean dust/metal powder, verify indicator operation; do not disassemble

7 Environment: Do not use underwater/rain (recommend cover against water); avoid strong acid/alkaline gases

8 Inrush current: Use a relay for loads with large inrush (e.g., lamps, motors)
