U-Link™ Plenum Universal Keypad Automation Cable is designed for use with Crestron, AMX and Lutron keypad to base station wiring in commercial and residential automation and conferencing systems. The U-Link ULK2218P 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 plenum rated for permanent installation, the U-Link ULK2218P can be installed in most plenum permanent installation environments.
