1 Rectangular standard type proximity sensor with DC 3-wire configuration (model PS12-4DNU)

2 Front-side sensing design with nominal sensing distance of 5mm (max 10% variation allowed)

3 Standard sensing target: 18×18×1mm iron block (10-15mm iron for hysteresis reference)

4 Wide DC power supply range: 12-24VDC (10-30VDC operation, 10-10mA current consumption)

5 Built-in protection circuits: Short circuit overcurrent and reverse polarity protection

6 IP67 protection structure (IEC standard) for dust and water resistance

7 Red LED operation indicator for real-time status monitoring

8 Excellent noise immunity via specialized sensor IC

9 Long service life, reliable performance, cost-effective for industrial applications

1 Industrial assembly lines: Detect metal components (bolts, gears) to control process flow

2 Packaging machinery: Count items or verify packaging material placement

3 Conveyor systems: Trigger sorting mechanisms at specific product positions

4 Robotic arms: Positioning and collision avoidance with metal objects

5 Material handling: Confirm proper loading/unloading of metal pallets/containers

6 Automotive manufacturing: Monitor metal part positions during assembly

7 Printing/paper processing: Detect metal guides/rollers for material alignment

1 Installation: Maintain minimum distance between sensors to avoid mutual interference

2 Wiring: Follow color codes (brown:+V, blue:0V, black:output) and ensure insulation

3 Environment: Operate at -25~70°C, 35-95% RH (no condensation); avoid strong magnetic fields

4 Load handling: Do not exceed rated load current; use bleeder resistors for small loads if needed

5 Protection: Avoid excessive shock/vibration (500m/s² shock,50m/s² vibration limits)

6 Safety: Read "Safety Considerations" in manual before use

7 Maintenance: Regularly clean sensor surface to remove dust/debris affecting performance
