TK Cables & Connectors – Technical Background & Applications
TK cables connect terminal equipment (phones, fax, DECT base stations) to connection boxes, patch panels and telephone systems. RJ11 cables (4-pin, 6P4C) are used for analogue telephone connections and modem connections; RJ12 cables (6P6C) provide two additional conductors for ISDN bus lines or powering terminals. RJ45 patch cables to TIA-568-B and ISO/IEC 11801 in classes Cat.5e to Cat.6A are standard in structured office cabling for VoIP phones. In industrial environments, shielded variants (S/FTP, SF/UTP) are often used to suppress interference from motor frequencies and control cabinets. TAE connection cables connect TAE outlets to analogue terminal equipment per the German building installation standard.
Matching connection boxes for TK cables: Connection Boxes. Patch panels for structured distribution: Patch Panels. For large cable quantities and project requests: sales@industry-electronics.com – we supply pre-assembled or by the metre.

Frequently Asked Questions
▶ Which cable for VoIP phones – Cat.5e or Cat.6? For VoIP phones, Cat.5e (100 MHz, 1 Gbit/s) is fully sufficient in most cases, as VoIP only requires a few kBit/s of bandwidth. Cat.6 (250 MHz) offers more headroom and makes sense if the same cable will later be used for 10GBase-T (with Cat.6A, 500 MHz). For new installations, we recommend Cat.6A directly, as the additional cost is manageable and future-proofing is higher. |
▶ RJ11 and RJ45 – can they be plugged into the same socket? Mechanically, an RJ11 plug (6P4C, narrower) can be inserted into an RJ45 socket, but this is not recommended: contact reliability is poor and can damage the socket. Conversely, an RJ45 plug does not fit into an RJ11 socket. For connecting analogue phones to RJ45 outlets, special TAE-to-RJ45 adapters are available that correctly map the pin assignment. |
▶ What does S/FTP and SF/UTP mean in shielding designations? The shielding designation per ISO/IEC 11801 follows the scheme XX/YZZ: the first abbreviation describes the overall shield (U=unshielded, F=foil, S=braid, SF=foil+braid), the second the pair shield (UTP=unshielded, FTP=foil, STP=braid). S/FTP = overall braid + individual foils per pair (highest shielding). SF/UTP = foil+braid overall, no individual shielding. For industrial TK cabling with strong EMC interference, we recommend S/FTP. |
