Solderless RJ45 to terminal block adapters provide a reusable connection solution resulting in a simple and convenient method of connecting products or devices with different types of signals over inexpensive UTP CAT5e or CAT6 cable without the use of tedious RJ45 connectors and crimp tools. If you need to change or modify your installation for use with different signal standards... no problem. Simply change the wiring with a small slotted screw driver - no additional connectors necessary. Includes cable tie mount on rear of terminal block for additional strain relief as well as a cable tie and strain relief boot cover.
