How to connect the fiber optic sensor to the wires

To connect a fiber optic sensor, typically connect the brown wire to 24V DC, the blue wire to 0V (ground), and the black wire to the signal input of a relay or controller.

Step-by-

Step Wiring Instructions

Identify the wires: Most industrial fiber optic sensors have three main wires: Brown wire: Positive power supply (24V DC)Blue wire: Negative or 0V (ground)Black wire: Signal output, which can be connected to a relay or control system. Connect the power supply: Attach the brown wire to the positive terminal of a 24V DC switching power supply. Attach the blue wire to the negative terminal (0V) of the power supply.

Connect the signal wire: The black wire is used to transmit the sensor's output signal. Connect it to the input of a relay, PLC, or other control device. Ensure the device is compatible with the sensor's output type (NPN/PNP, light-on/dark-on),.

Check the fiber optic connections: The sensor has a transmitter (T) and receiver (R) for the optical fiber. Insert the fiber optic cable into the transmitter and receiver ports, ensuring proper alignment. Power on and configure: Once powered, the sensor's LED display will show the current light intensity.

Use the SE

T key to calibrate the sensor by placing the detected object at the farthest and closest positions, allowing the sensor to calculate the trigger light intensity. Adjust output mode (DARK-ON or LIGHT-ON) and sensitivity as needed.

Additional Tips

Secure the fiber: Use adhesive, tape, or mounting brackets to prevent movement, which can affect signal accuracy. Environmental protection: If the sensor is exposed to dust or moisture, consider protective enclosures or coatings. Connector type: For professional installations, fiber optic connections may use FC/APC connectors or require fusion splicing for long-distance or outdoor applications.

By following these steps, you can safely and effectively connect a fiber optic sensor to a power source and control system, ensuring accurate detection and reliable operation.
