Shielded Toolless RJ45 Field Termination Plug Cat8.1, Schneider Electric 791199, 40G, STP, Gold Contacts, Metal Housing, Blue

Shielded Cat8.1 toolless RJ45 field termination plug by Schneider Electric (model 791199) delivers a compact, field-installable solution for fast, high-quality cable terminations in high-speed network environments. Designed for use with shielded twisted-pair (STP/U‑FTP) cables, this plug supports up to 40GBase-T performance and is compatible with both solid and stranded conductors. The plug features 3 micro-inch gold-plated contacts, a full metal housing with 360° shielding and a blue male RJ45 connector in a compact 12×58 mm form factor, sold as a single unit.

Advantages

The toolless design enables quick assembly without special tools, reducing installation time in data center top-of-rack and middle-of-row deployments. Gold-plated contacts and continuous shielding preserve signal integrity for high-bandwidth and PoE applications. The metal housing provides mechanical robustness and effective EMI protection while supporting a wide operating temperature range for reliable performance in varied environments.

Suitable for

• Top-of-rack (ToR) and middle-of-row (MoR) cabling in data centers
• High-speed 25GBase-T and 40GBase-T network links
• Power over Ethernet deployments up to IEEE 802.3bt / PoE++ / 4PPoE
• Field terminations where rapid, tool-free assembly is required

How to use

Prepare the shielded network cable by stripping the outer jacket and arranging pairs according to the chosen wiring standard (T568A or T568B). Insert the conductors into the plug body following the color coding, ensure the foil and drain wire are routed to make contact with the plug shield, then close the housing to secure contacts and engage the strain relief. No special crimping tools are required; verify continuity and shielding with a cable tester after assembly to confirm correct termination and integrity.

Usage recommendations

For optimal performance, use shielded Cat8.1 U/FTP cable of compatible conductor size, maintain proper pair untwist lengths during termination, and ensure the drain wire or foil makes reliable contact with the plug housing. Test each terminated link for continuity, crosstalk and return loss when installing for 25G/40G or PoE++ applications.
