How to use

Strip the flat cable to the required length, align the individual conductors in the correct pinout, and insert them fully into the RJ45 connector until the conductor ends are visible in the front of the housing. Place the connector into an appropriate crimping tool and perform a single crimp action to secure the contacts and strain relief. Verify the connection visually through the transparent housing and, if required, test continuity with a cable tester.

Recommendations

Use compatible crimping tools: Art.-No. E-MUC410 for RJ10/RJ11/RJ12/RJ45 and Art.-No. 39945.2 for RJ69. For reliable results, ensure conductors are straight and fully inserted before crimping and use a suitable cable tester after termination.
