## Long description

The EFB Elektronik 37518.1-100 wire connector is an unshielded RJ12 (6P6C) modular plug designed for use with round U/UTP (UTP) cables. The transparent connector comes in a pack of 100 and is intended for telecommunications and networking applications requiring RJ-12 terminations.

Supplied in a quantity of 100, the pack supports multiple terminations and small installations. Designed for round cables and compatible with common RJ crimping tools specified for RJ10/RJ11/RJ12 and RJ45.

How to use
Strip the outer jacket of the round U/UTP cable to expose the individual conductors, align conductors according to the required pinout for RJ12, and fully insert the wires into the transparent RJ12 connector until they reach the end. Use an appropriate crimping tool for RJ10/RJ11/RJ12 (for example Art.-No. E-MUC410) or a compatible RJ crimper to terminate the connector. Verify correct seating and electrical continuity after crimping.
