Looking for a secure, professional, and interference-free network connection? Installing shielded RJ45 connectors is essential to ensure maximum protection and performance in Ethernet networks, especially in industrial or high-demand environments. In this comprehensive guide, you'll learn, step by step, how to properly install shielded RJ45 connectors, what tools you'll need, the most common mistakes, and expert tips for achieving a perfect and long-lasting connection.
Why choose shielded RJ45 connectors?
Shielded RJ45 connectors (STP/FTP) are designed to minimize electromagnetic interference (EMI) and crosstalk, protecting the data signal and ensuring stable transmission even in environments with a high concentration of electrical or industrial equipment. They are ideal for:
- Enterprise and data center networks
- Industrial facilities
- Wiring outdoors or in areas with electrical noise
- High-speed applications (Cat6A, Cat7, Cat8)
In addition, shielded connectors offer greater durability and mechanical resistance, making them perfect for demanding installations.
Tools and materials needed
Before you begin, gather the following items for a professional and trouble-free installation:
- Shielded Ethernet cable (Cat6A, Cat7, Cat8)
- Shielded RJ45 connectors compatible with the cable type
- Crimping tool for shielded RJ45 connectors
- Wire stripper or precision knife
- Scissors or pressure cutters
- Network tester to verify the connection
- Protective boot (optional, but recommended to prolong the life of the connector)
Types of shielded RJ45 connectors
There are different models depending on the category and installation method:
- Through-hole connectors : These allow wires to pass through the connector before crimping, making alignment easier and reducing errors.
- Tool-less field connectors : Ideal for quick installations without a crimper, especially outdoors or during maintenance.
- Standard connectors : These require a crimping tool and are the most common in professional installations.
Step by step: Installation of shielded RJ45 connectors
1. Prepare the cable
- Measure and cut the Ethernet cable to the desired length.
- Strip the outer covering of the cable (approx. 2-3 cm) using the wire stripper, taking care not to damage the inner pairs or the shielding.
- Unwind and straighten the wire pairs. If the cable has a ground wire or shielding braid, separate them and set them aside for the next step.
2. Prepare the armor
- Twist the shielding mesh and the ground wire together, forming a compact braid.
- If the connector requires it, place the mesh and ground wire in contact with the metal casing of the connector to ensure continuity of protection.
3. Arrange the cables according to the standard
The order of the cables is fundamental for correct transmission. The most widely used standards are T568A and T568B . T568B is the most common in commercial networks.
Make sure to align and cut the wires so they are even and fit completely into the connector.
4. Insert the cables into the connector
- With the clip facing down , insert the wires into the shielded RJ45 connector, making sure each one goes all the way in and is in the correct order.
- If you use a through-connector, the wires will come out the end and you can visually check the alignment before cutting off the excess.
5. Crimp the connector
- Place the connector in the crimping tool and apply firm pressure so that the internal blades pierce the insulation and make contact with the conductors.
- For shielded connectors, ensure the metal housing fits snugly against the cable's shielding. Some crimping tools have a special section for crimping the outer shielding.
- If you are using tool-less field connectors, follow the manufacturer's instructions for closing the connector and securing the contacts.
6. Install the protective boot (optional)
- Slide the protective boot over the connector to prevent mechanical damage and extend the cable's lifespan, especially in installations where cables are frequently handled.
7. Verify the connection
- Use a network tester to check the continuity and correct order of the cables.
- Check that the shielding is connected and that there are no short circuits or loose wires.
Expert tips for a perfect installation
- Invest in quality tools : A professional crimping tool and certified connectors ensure reliable and long-lasting connections.
- Do not force the cables : If the cables do not go in easily, check the order and alignment before crimping.
- Keep the shielding intact : The shielding must be in contact with the metal housing of the connector to ensure EMI protection.
- Avoid excessive cutting : Leave enough cable length so that the sheath reaches the connector, preventing the pairs from being exposed.
- Check the standard : Always confirm the wiring standard (T568A/B) before crimping.
Common mistakes and how to avoid them
- Incorrect cable order : Causes network failures and signal loss. Double-check before crimping.
- Poorly connected shielding : Reduces EMI protection and can cause interference.
- Use of unsuitable tools : Can damage cables or connectors, resulting in unreliable connections.
- Do not use protective boots : The connector is exposed to mechanical damage and moisture.
