18-5 Shielded VNTC Tray Cable, TFFN/PVC

This 18 AWG, 5-conductor shielded VNTC (Vinyl Nylon Tray Cable) is a dual-rated Type TC-ER industrial cable. It is specifically engineered for multi-circuit control and instrumentation signaling in demanding environments. By combining flexible TFFN conductors with a 100% foil shield, it ensures superior protection against electromagnetic interference (EMI) while allowing for streamlined installation without conduit.

Key Features of 18-5 Shielded VNTC (TC-ER)

• Exposed Run (TC-ER) Rated: This cable is UL 1277 rated for high crush and impact resistance. Per NEC 336.10, it can transition from a cable tray to equipment for up to 6 feet without the need for conduit or continuous support, reducing both labor and material costs.

• 100% EMI/RFI Shielding: Featuring an overall aluminum foil-polyester tape shield and a tinned copper drain wire, this cable provides a total barrier against electrical noise, protecting sensitive low-voltage signals from nearby power leads.

• Flexible TFFN Conductors: Utilizing TFFN (Thermoplastic Flexible Fixture Nylon) stranded conductors makes this cable significantly easier to strip and terminate in crowded control panels compared to standard THHN.

• Rugged Industrial Jacket: The flame-retardant, sunlight-resistant PVC jacket is moisture and oil-resistant, approved for direct burial and use in Class I, Division 2 hazardous locations.

Common Applications

• Complex Sensor Interconnects: Ideal for sensors requiring multiple wire legs (such as 4-wire RTDs with a ground or shield drain) in noisy industrial environments.

• Industrial Automation: Consolidates multiple power or signal legs into a single, flexible shielded run for robotic cells and automated assembly lines.

• Process Control Logic: Used for 24V DC or 120V AC control circuits where additional conductors are needed for switched legs or feedback loops.

• Relay and Solenoid Wiring: Managing small banks of actuators where conductor density and noise suppression are required for reliable operation.

Technical Note: To ensure the shield functions effectively, the tinned copper drain wire should be properly terminated to a ground bus at the source end only. This prevents ground loops while allowing the shield to drain induced interference. Always ensure the cable is secured and protected from physical damage according to NEC requirements when utilizing the TC-ER rating.
