2. Main Features

• Model: 6210000

• Type: Inductive proximity sensor

• Detectable materials: All metal objects

• Supply voltage: 10–30 V DC

• Output type: 3-wire DC

• Max load current: ≤ 200 mA

• Protection class: IP67 dustproof & waterproof

• Operating temperature: -25 °C ~ +70 °C

• Built-in reverse polarity, overvoltage and short-circuit protection

• Vibration resistant, shockproof, long service life

3. Safety Precautions

• Disconnect power before installation and wiring.

• Do not exceed rated voltage 10–30 V DC.

• Reverse power wiring is strictly prohibited to prevent sensor damage.

• Keep away from high-power motors and transformers to avoid magnetic interference.

• Do not disassemble or modify the sensor structure arbitrarily.

• Avoid mechanical impact, oil corrosion and long-term damp working environment.

4. Installation Guide

1. Fix the sensor with lock nut or mounting bracket.

2. Keep standard effective sensing distance from the metal target.

3. Install perpendicular to the detected metal surface for best accuracy.

4. Do not place extra metal parts near the sensing head.

5. Arrange cables properly, avoid sharp bending and forced pulling.

5. Wiring Definition

• Brown  : DC +10～30 V Power

• Blue   : DC 0 V Ground

• Black  : Signal output

• Shield : Ground only at controller side

6. Operating Instructions

1. Wire strictly in accordance with standard definition.

2. Power on, the sensor enters standby state.

3. When metal enters effective sensing range, indicator lights up and outputs signal.

4. When metal moves away, signal resets and indicator turns off.

5. Suitable for PLC, relay and industrial automation controller input.

7. Troubleshooting

• No indicator light: Check power supply and wiring circuit.

• Always output signal: Metal too close or surrounding metal interference.

• Unstable flickering: Loose wiring, mechanical vibration or voltage fluctuation.

• Indicator on but no output: Signal wire breakage or load damage.

8. Maintenance

• Regularly clean dust and iron scraps on the sensing surface.

• Periodically check mounting tightness and cable wear & aging.

• Avoid long-term operation in high temperature and corrosive gas environment.

• Replace the sensor in time if shell crack or cable damage occurs.
