2. Main Features

• Model: 6203590

• Type: Inductive proximity sensor

• Detectable objects: All metal materials

• 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 connection is strictly prohibited to avoid burnout.

• Keep away from high-power motors, transformers and strong magnetic interference.

• Do not disassemble or modify the sensor privately.

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

4. Installation Guide

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

2. Maintain standard effective sensing distance from metal target.

3. Install perpendicular to the detected surface for optimal detection accuracy.

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

5. Route 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 according to standard definition.

2. Power on, the sensor enters standby mode.

3. When metal enters effective sensing range, indicator lights up and output activates.

4. When metal leaves the detection area, output resets and indicator turns off.

5. Compatible with PLC, relay and automation controller input terminals.

7. Troubleshooting

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

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

• Unstable flickering: Loose wiring, equipment vibration or power fluctuation.

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

8. Maintenance

• Clean dust and iron debris on the sensing surface regularly.

• Periodically check mounting tightness and cable wear.

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

• Replace the sensor timely if shell crack or cable aging occurs.
