This 16 AWG, 7-conductor shielded VNTC (Vinyl Nylon Tray Cable) is a robust, dual-rated Type TC-ER industrial cable. Engineered for medium-density control and instrumentation circuits, it offers a 16 AWG conductor gauge for higher current capacity and 100% foil shielding to protect sensitive signals. The TC-ER (Exposed Run) rating provides significant installation flexibility by allowing the cable to transition from a tray to equipment without the need for conduit.

Key Features of 16-7 Shielded VNTC (TC-ER)

• Exposed Run (TC-ER) Rated: This cable meets the rigorous crush and impact standards of UL 1277. Per NEC 336.10, it can be routed outside of a cable tray to the equipment it connects for up to 6 feet without continuous support or conduit, lowering labor costs.

• 100% EMI/RFI Shielding: Equipped with an overall aluminum foil-polyester tape shield and a tinned copper drain wire. This construction ensures total coverage, preventing electromagnetic interference from surrounding motor leads and high-frequency machinery.

• Enhanced Conductor Capacity: The 16 AWG gauge provides lower resistance and higher current-carrying capacity than 18 AWG, making it ideal for longer circuit runs where voltage drop might be a concern.

• Flexible TFFN Conductors: Utilizing TFFN (Thermoplastic Flexible Fixture Nylon) stranded conductors ensures the cable remains manageable during installation, making it easier to pull through trays and terminate in crowded control enclosures.

Common Applications

• Multi-Circuit Control Logic: Connecting PLC cabinets to machinery requiring several control points, such as sensor arrays, solenoids, and motor starters.

• Industrial Automation: Ideal for robotic cells and automated assembly lines where conductors must drop from overhead trays directly to machine-mounted junction boxes.

• Utility & Power Monitoring: Managing telemetry, status signaling, and control logic in power plants and substations where electrical noise is constant.

• Process Instrumentation: Suitable for multi-point feedback and sensor monitoring in refineries, chemical plants, and water treatment facilities.

Technical Note: To maximize the effectiveness of the shield, the tinned copper drain wire should be landed at a ground bus at the source end only. This configuration prevents ground loops. Given the 7-conductor 16 AWG construction, ensure that tray load and conduit fill calculations are verified prior to installation due to the cable’s specific diameter and weight.
