U-Link™ Universal Keypad Automation Cable



22AWG Signal Conductors - low-loss conductors for signal elements

18AWG Aux Conductors - larger low power loss conductors for auxiliary elements

For Lutron, AMX or Crestron Keypads - universal design works with multiple system types

UL Rated - suitable for installation in many permanent install applications

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.
