RJ45 connectors NORDMARK CAT5 STP/FTP for LAN cable, pack with shielded RJ45 plugs (model RJ45F)

Shielded RJ45 connectors NORDMARK CAT5 STP/FTP (model RJ45F) are metal-bodied RJ45 plugs intended for terminating Category 5 shielded twisted-pair LAN cables. These connectors are made to mate with STP/FTP cable types, providing a grounded metal shield around the contact area to reduce electromagnetic interference and maintain signal integrity in environments with potential sources of noise. The design supports standard 8P8C wiring and is suitable for creating patch cords, custom-length Ethernet leads and fixed network terminations where a shielded connection is required.

Advantages

Metal shielding around the plug ensures improved protection against external electromagnetic and radio-frequency interference compared with unshielded connectors. The connectors are compatible with Category 5 performance requirements and accommodate shielded twisted-pair conductor geometry for consistent contact and reliable data transmission. Their construction enables proper connection of the cable shield to the plug body to maintain continuity for grounding and help reduce signal degradation over short and medium runs.

Suitable for

• Assembling shielded Cat5 patch cables and custom Ethernet leads
• Network terminations in environments with EMI/RFI concerns
• Connecting STP/FTP cable in offices, server rooms and industrial spaces
• Replacement of damaged RJ45 plugs on shielded cable runs

Key specifications

• Connector type: shielded 8P8C RJ45 plug
• Category support: Category 5 (Cat5)
• Cable compatibility: shielded twisted-pair (STP) and foiled twisted-pair (FTP)
• Contact configuration: 8 conductors (standard Ethernet pinout)
• Body material: metal shield with insulated inner housing
• Grounding: shield termination for cable drain wire or foil grounding

How to use

Strip the outer jacket of the STP/FTP cable to expose the twisted pairs and the cable shield, taking care to preserve pair twists as much as possible. Fold or prepare the drain wire/foil to provide contact with the plug’s shield termination. Arrange the individual conductors in the chosen wiring order (T568A or T568B), insert them fully into the connector so each conductor reaches its contact, then press or crimp the plug using a compatible RJ45 crimping tool designed for shielded plugs. Ensure the metal shield of the plug makes firm contact with the cable shield to establish grounding; verify continuity and correct wiring with a network cable tester before installation.

Usage recommendations

Use these shielded RJ45 plugs with proper crimp tools and follow industry wiring standards (T568A/T568B). Maintain minimal untwisting of pairs and ensure the cable shield is securely connected to the plug shield for effective EMI protection. Test each assembled cable for wiring correctness and signal continuity before deploying in active networks.
