18 AWG · 2-conductor · CMP/FT6 plenum rated · stranded bare copper
This 18/2 twisted, shielded cable is built for low-voltage control and signal lines in plenum spaces. It’s ideal for HVAC controls, communicating thermostats, BAS/RS-485 runs, sensors, and security. Twisted pairs help reject noise, while the overall foil shield adds an extra layer of protection from interference. The CMP/FT6 plenum jacket meets strict flame and smoke requirements and pulls cleanly from a reel-in-a-box.
Key Features
Keeps Signals Clean
Twisted pair plus overall foil shield minimize electrical noise for reliable control and data.
Plenum-Ready Jacket
CMP/FT6 rated for use in environmental air spaces above ceilings and returns.
Flexible, Durable Conductors
Stranded bare copper makes long pulls and tight bends easier without kinking.
Easy Handling
Supplied in a 1000-ft reel-in-a-box to speed setup and reduce tangles.
Typical Uses
- Thermostat and sensor wiring in HVAC/BAS
- RS-485 (e.g., BACnet MS/TP) and other low-speed control networks in plenum spaces
- Security and access-control terminations needing shielded 18/2 control cable
