How to connect the plastic fiber optic cable for the sensor

Plastic fiber optic cables can be connected to sensors by cutting and preparing the fiber ends, inserting them into the sensor's mounting slot, and securing them with the mounting slide or heat-shrink tubing.

Step 1: Prepare the Fiber

• Cut the fiber to the required length using a proper fiber optic cutter or a sharp hobby knife. Ensure the cut is clean and straight to minimize signal loss .
• Polish the fiber end by gently sanding it on flat sandpaper (200–600 grit) to create a smooth surface for optimal light transmission .
• Clean the fiber with a dry, lint-free cloth to remove dust or debris. Avoid solvents that could damage the plastic .

Step 2: Insert the Fiber into the Sensor

• Open the sensor's mounting slide using a screwdriver or the tool provided with the sensor .
• Insert the prepared fiber end into the designated opening of the sensor until it is fully seated .
• Close the mounting slide to secure the fiber in place. For a stronger connection, you can use adhesive or heat-shrink tubing over the junction .

Step 3: Configure the Sensor

• Select the switching mode (normally open or normally closed) using the sensor's rotary selector and buttons .
• Set the output type (PNP, NPN, or push-pull) according to your system requirements .
• Adjust the sensing distance using the potentiometer or the teach-in function to ensure the sensor detects objects at the desired range .

Step 4: Test the Connection

• Verify that the sensor responds correctly to light reflection or beam interruption.
• Ensure the fiber is stable and not bent sharply, as excessive bending can reduce signal quality .

Additional Tips

• Use coiled fiber assemblies if the fiber will move or flex frequently .
• Avoid exposing the fiber to harsh chemicals or extreme temperatures beyond the sensor's specifications .
• For experimental setups, heat-shrink tubing can provide a simple, temporary connection . Following these steps ensures a secure, efficient connection between a plastic fiber optic cable and a sensor, providing reliable signal transmission for your application.
