Shielded RJ45 connectors include a metal shield and are designed for use with shielded datacomm cable and compatible grounded components, which can help limit electromagnetic interference. Unshielded RJ45 connectors are designed for unshielded cable and are commonly used for standard network terminations where shielding is not part of the cabling system.

Use pass-through RJ45 connectors when you want to verify the wire sequence visually before crimping, which can help speed terminations and reduce wiring errors. They are available for compatible Cat5e and Cat6 solid or stranded cable, while standard connectors may suit installations where pass-through termination is not needed or where the connector and crimp tool are specified for that cable.

Many RJ45 connectors support both solid and stranded cable, including compatible Cat5e and Cat6 options. Check the connector specifications and match them to the cable category, conductor size, and shielded or unshielded construction before termination.

When selecting a crimp tool for RJ45 connectors, confirm that it supports the connector style you use, such as pass-through or standard plugs, and the cable’s wire type and gauge, including 28 to 22 AWG solid or stranded conductors. Features such as cutting, stripping, flush trimming, and an on-tool wiring guide can help streamline cable preparation and termination.
