How to Choose the Right RJ45 Pass-Through Connector for Ethernet Connection

1. Understand the Basics:

RJ45 connectors are commonly used for terminating Ethernet cables. They come in various types, including shielded and unshielded variants.

The correct terminology for these connectors is 8P8C (eight position, eight contact) modular plugs. However, they are often referred to as “RJ45” for simplicity.

2. Shielding:

Determine whether your cable is shielded or unshielded. Use shielded RJ45 connectors for shielded cables and unshielded connectors for unshielded cables.

Using a shielded connector on an unshielded cable won’t provide any benefit and may mislead others.

3. Research and Specifications:

Look for detailed specifications from reputable manufacturers. Avoid those that don’t provide complete information.

Pay attention to the fitment of the connector. It’s not about the cable category (e.g., Cat5e, Cat6, Cat6A), but rather the connector size that matters.

4. Pass-Through Connectors:

Pass-through connectors allow a push-pull method to seat the cable jacket as far into the plug as possible. This minimizes crosstalk.

Consider using Cat6/6A Pass-Through RJ45 connectors for optimal results. These connectors are designed for ease of use and reliable termination1.

5. Check the Connector Quality:

Look for connectors with:

A bright, transparent, and smooth housing.

A retaining latch that can fold over 180 degrees without losing elasticity.

Properly aligned eight contact pins2.

6. Wiring Standards:

RJ45 connectors follow either the T568A or T568B wiring standard. Ensure your connectors match the wiring convention used in your network.

7. Best Practices:

Use a cable tester to verify proper termination after installation.

Remember, the right RJ45 connector ensures a solid connection and reliable data transmission. Choose wisely, and your Ethernet network will thank you!
