This 18 AWG, 2-conductor shielded VNTC (Vinyl Nylon Tray Cable) is a specialized industrial control cable designed for signal transmission and low-voltage power. By utilizing TFFN (Thermoplastic Flexible Fixture Nylon) conductors, this cable offers enhanced flexibility for routing through conduits and complex tray systems, while the overall shield ensures protection against electrical noise.

Key Features of 18-2 Shielded VNTC

• Flexible TFFN Conductors: The use of TFFN (stranded) copper conductors makes this cable significantly easier to strip and maneuver in tight spaces, such as crowded junction boxes or small control enclosures, compared to standard THHN.

• 100% EMI/RFI Shielding: Features an overall aluminum foil-polyester tape shield with a tinned copper drain wire. This construction provides a total barrier against electromagnetic interference, preventing “cross-talk” and signal corruption in sensitive circuits.

• Standard Power Color Coding: The Black and White conductor pairing is ideal for 120V AC control circuits or any application requiring a clear hot-and-neutral identification.

• Industrial Durability: The flame-retardant and sunlight-resistant PVC jacket is engineered for industrial environments. It is resistant to moisture, heat, and oils, and is approved for use in Class I, Division 2 hazardous locations.

Common Applications

• Instrumentation & Signal Loops: Connecting 4-20mA transmitters or other low-voltage sensors to PLC input modules in industrial plants.

• Security & Alarm Systems: Used in commercial and industrial settings for shielded power and signal runs for sensors or gate controllers.

• Micro-Processor Interconnects: Providing clean, shielded paths for digital communication lines to ensure data integrity.

• Control Power: Ideal for 120V AC or 24V DC circuits powering small relays, solenoids, or pilot lights where noise suppression is desired.

Technical Note: As a standard Type TC cable, this product is designed for installation in cable trays, conduits, or raceways. It is not TC-ER (Exposed Run) rated, which means it cannot be run as an “exposed” cable between the tray and equipment without the protection of conduit or continuous support. To maximize the effectiveness of the shield, terminate the drain wire to a clean ground at the source end only.
