This 16 AWG, 37-conductor shielded VNTC (Vinyl Nylon Tray Cable) is an ultra-high-density Type TC-ER industrial cable. It is designed for massive signal consolidation in complex automation and control systems. The combination of flexible TFFN conductors and a 100% foil shield ensures superior performance in environments with extreme electromagnetic interference (EMI).

Key Features of 16-37 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 conduit, significantly reducing installation time and hardware costs.

• 100% EMI/RFI Shielding: An overall aluminum foil-polyester tape shield and tinned copper drain wire act as a total barrier against electrical noise, protecting up to 37 sensitive signals from cross-talk or external interference.

• Superior Conductor Strength: The 16 AWG conductors offer a higher ampacity and physical pull-strength than 18 AWG, making this cable ideal for longer runs and more demanding power-limited circuits.

• Flexible TFFN Conductors: Stranded TFFN (Thermoplastic Flexible Fixture Nylon) conductors provide much-needed flexibility for a cable of this diameter, making it easier to pull through trays and terminate in dense control panels.

Common Applications

• Centralized Logic Control: Connecting main PLC frames to massive field terminal blocks or multi-stage machinery.

• Power Plant & Utility Monitoring: Ideal for comprehensive telemetry, status signaling, and control logic in high-voltage environments.

• Refinery Instrumentation: Built to withstand the chemical and moisture-heavy environments found in treatment plant raceways and trays.

• Robotic Cell Integration: Consolidating feedback, power, and signal lines for high-conductor-count automated manufacturing systems.

Conductor Identification: E2 Color Code

The conductors are identified using the industry-standard E2 color sequence (Black, Red, Blue, Orange, Yellow, Brown, then repeated with various stripes). This systematic coding allows for the quick and accurate identification of each of the 37 individual conductors during termination.

Technical Note: To ensure the shield functions as intended, the tinned copper drain wire should be properly terminated to a ground bus at the source end only. Because this cable has 37 conductors at a 16 AWG gauge, it has a significant outside diameter and weight; ensure your tray system or conduit fill calculations are verified prior to installation.
