M85485/12-18T2A is a 18 AWG Two conductor, Tin coated Copper conductor, Tin shielded and jacketed frequency absorptive cable

Filterline is a "radio frequency absorptive wire” composed tiny particles of conductive material incorporated into the second layer of a 3-layer hookup wire. These conductive particles intercept and block (filter) out typically low-frequency electrical interferences from other outside sources. This technology allows a signal to be transmitted from the control to the component without being harmed or interrupted.
