Clark’s U-Link™ ULK2218 is a universal control cable designed for use with Crestron, AMX and Lutron keypad to base station wiring in commercial and residential automation and conferencing systems. The U-Link ULK2218 has two twisted pair elements under a single-jacket to provide separate elements for the signal and power feeds to the keypad. To provide low attenuation, the data pair has a low-capacitance foam dielectric that reduces the high frequency signal attenuation within the pair. UL rated for permanent installation, the U-Link ULK2218 can be installed in most non-plenum permanent installation environments.
