Telex 4015-50 25-Pair Cable Assembly

The 4015-50 is a factory-terminated 50-foot 25-pair cable assembly for RTS and Telex wired intercom systems, part of the 4000 Series IFB and two-wire family. It bundles the many audio-and-power pairs a partyline needs into one run, so an installer pulls a single cable between a power supply, a junction, and the station field rather than lacing up individual lines.

With the pairs grouped and terminated at the factory, the 4015-50 shortens shop time and keeps a two-wire install repeatable. This is the 50-foot version; the 100-foot 4015-100 covers longer throws when the station field sits farther from the rack.
