The RJ45 Male to 8-Position Side Terminal Block Adapter from Calrad Electronics provides a reusable way to connect video, control, and mixed analog signal devices together. On one end of the 6" pigtail cable is an RJ45 male connector with an solderless 8-position side terminal block on the other, which allows you to link different signal types using Cat 5e or 6a wiring without needing a crimping tool.
To change or modify your installation for use with different signals, you simply need to change the wiring with a small slotted screw driver. No additional connectors are needed. Each terminal block position is labeled, and they're designed to work with 22 to 24 AWG wire.
