M85485/12-24U1A is a 24 AWG Single conductor, Silver coated High Strength copper alloy 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.
