## Summary description

Kit of 20 DATACOM adapters converting RJ45 plugs to RJ12 and RJ11 connectors. Designed for adapting network or telephony cables where smaller modular connectors are required. Useful for connecting legacy telephone devices, PBX lines or modems to modern cabling; simplifies installations and reduces the need for new cable runs.

## Long description

Kit of 20 DATACOM adapters that convert an RJ45 plug to RJ12 and RJ11 connectors, enabling the connection of telephony devices and smaller modular jacks to cables terminated with RJ45. The DATACOM RJ45 to RJ12/RJ11 Adapter kit is intended for situations where existing structured cabling uses RJ45 plugs but endpoints require 6‑ or 4‑position telephone connectors. The kit contains multiple adapters to support small installs, repairs, or quick changes without re‑terminating cabling.
Advantages
The adapters provide a compact mechanical interface that preserves the RJ45 plug while presenting an RJ12 or RJ11 socket, eliminating immediate recabling. Supplied as a pack of 20, the kit reduces installation time by offering ready‑to‑use adapters for multiple lines. Construction is designed for stable contact with common modular plugs and repeated insertions typical for telephony and legacy modem equipment.
Suitable for
Connecting legacy telephones and PBX handsets to structured cabling
Adapting RJ45 terminated patch cords to RJ12/RJ11 devices
Temporary or maintenance connections in offices, call centres and small network closets
Testing or troubleshooting telephone lines without re‑terminating cables
Key specifications
Contents: 20 adapters per kit
Input interface: RJ45 plug (8P8C)
Output interfaces: RJ12 (6P6C) and RJ11 (6P4C) compatible sockets
Material: durable plastic housing with metal contact pins
Contact design: modular contacts compatible with standard telephone plugs
Usage environment: indoor network and telephony installations
How to use
Insert the RJ45 plug of an existing cable into the adapter’s RJ45 inlet until it clicks, then connect the telephone or modem cable to the adapter’s RJ12 or RJ11 socket. Verify the correct seating of plugs and test the line for voice or data signalling as required. The adapter is passive and requires no power; it simply maps the relevant conductor pairs through to the smaller connector. For multi‑pair cables, ensure the intended pairs correspond to the device pinout before use.
Usage recommendations
Use the adapters for temporary or retrofit connections rather than as a permanent replacement for proper terminations. Avoid exposing the adapters to moisture or excessive mechanical stress; route and secure cables to prevent bending at the adapter interface. Confirm pinout compatibility between the cabling and the device to prevent miswired connections.
