产品特点 FEATURES

1 Long sensing distance: Up to 2 times longer than standard models (PRDAT18-7DO has a sensing distance of 7mm)

2 Spatter resistance: PEFE coating on the sensing area prevents adhesion of welding spatter, suitable for welding environments

3 Built-in protection circuits: Includes surge protection and short circuit over current protection to enhance durability

4 Red LED operation indicator: Clearly shows the sensor's working status

5 IP67 protection rating: Complies with IEC standards, resistant to dust and water immersion up to 1m for 30 minutes

6 DC 2-wire type: Easy to integrate into existing DC 2-wire systems, replaceable for spatter-resistant type limit switches

7 Stable performance: Response frequency of 250Hz, insulation resistance of 20MΩ (at 500V DC), vibration resistance (1.5mm amplitude, 10-55Hz for 2h per axis)

使用场景 APPLICATIONS

1 Welding workstations: Ideal for detecting metal parts in welding processes where spatter is common, as it resists spatter adhesion

2 Automotive assembly lines: Used to detect presence of metal components (e.g., body panels) during assembly, especially near welding operations

3 Metal fabrication plants: Position detection of metal workpieces on production lines, even in environments with mechanical shocks or spatter

4 Conveyor systems for metal items: Triggers actions (start/stop) when metal parts pass a specific point, leveraging long sensing distance

5 Industrial machinery replacement: Can replace older spatter-resistant limit switches in DC 2-wire setups, reducing maintenance costs

注意事项 PRECAUTIONS

1 Load connection requirement: For DC 2-wire type, connect the load before supplying power to avoid internal component damage; load can be connected to either wire

2 Residual voltage handling: If load current is small, add a bleeder resistor in parallel with the load to prevent return failure (use formula R=(Vs-Vr)/Is to calculate resistor value)

3 Mutual interference prevention: Maintain minimum distances between adjacent sensors (PRDAT18-7DO: parallel distance A=42mm, face-to-face B=58mm, etc.)

4 Metallic panel mounting: Keep a safe distance from metallic panels to avoid interference (follow specified dimensions for PRDAT18-7DO)

5 Environmental limits: Operate within -25°C to 70°C, avoid corrosive gases/liquids, and do not exceed vibration/shock specs

6 Safety first: Read the "Safety Considerations" section in the instruction manual before using the sensor
