4. Installation Guide
Follow these steps to properly terminate an Ethernet cable with the Cable Matters CAT6 RJ45 Modular Plugs. A crimping tool designed for RJ45 connectors is required for this process.
- Prepare the Cable: Use a cable stripper to carefully cut and strip the outer jacket of the Ethernet cable, exposing the twisted pairs.
- Arrange the Wires: Untwist the wire pairs and arrange them according to the T568A or T568B wiring standard. Ensure the wires are straight and parallel.
- Insert the Wires: Carefully insert the arranged wires into the RJ45 plug, ensuring each wire slides into its designated channel. Push the wires firmly until they reach the front of the connector and the cable jacket is seated inside the plug for strain relief. The transparent housing allows for visual verification of correct wire placement.
- Crimp the Plug: Place the RJ45 plug into the appropriate slot on your crimping tool. Squeeze the handles of the crimping tool firmly until the connector is fully crimped. This action pushes the gold-plated contacts into the individual wires, establishing electrical connection.
- Verify Connection: Use an Ethernet cable tester to identify any miswires, opens, or shorts, and confirm that the cable functions properly.

For enhanced cable durability and protection of the locking clip, consider using Cable Matters RJ45 strain relief boots (sold separately).
5. Maintenance and Storage
The Cable Matters RJ45 Modular Plugs come in a reusable storage jar. To maintain the quality and organization of your connectors:
- Store unused plugs in the provided jar to protect them from dust, moisture, and physical damage.
- Ensure the screw-on lid is securely fastened when not in use.
- Keep the jar in a cool, dry place.

6. Troubleshooting
If you encounter issues during the termination process or with cable performance, consider the following:
- Cable Not Fitting: Verify that your Ethernet cable's specifications (wire gauge, conductor insulation diameter, and overall outer diameter) match the requirements for these plugs (23-28 AWG, 0.89-0.99mm conductor insulation, max 5.7mm outer diameter). Cables with larger conductors or thicker insulation may not fit correctly.
- Poor Connection/No Signal:
- Ensure wires are fully inserted to the front of the connector before crimping.
- Confirm the correct wiring standard (T568A or T568B) is followed on both ends of the cable.
- Check that the crimping tool has properly seated all 8 gold-plated contacts into the wires.
- Use a cable tester to identify any miswires, opens, or shorts.
- Damaged Locking Clip: If the locking clip breaks, the connection may not be secure. Consider using strain relief boots to protect the clip during frequent plugging and unplugging.
