18-8 Shielded VNTC Tray Cable, TFFN/PVC

Streamline your industrial wiring with this TC-ER rated 18/8 shielded tray cable. Designed for high-density applications, its Exposed Run (ER) rating eliminates the need for conduit when transitioning from cable trays to machinery, saving both time and material costs. The flexible TFFN conductors and full foil shielding ensure easy routing and uncompromised signal integrity.

Key Features of 18-8 Shielded VNTC (TC-ER)

• Exposed Run (TC-ER) Rated: This cable has passed the rigorous UL 1277 crush and impact tests. Per NEC 336.10, it can be routed between a cable tray and the equipment it connects for distances up to 6 feet without continuous support or conduit.

• Flexible TFFN Conductors: Utilizing TFFN (Thermoplastic Flexible Fixture Nylon) stranded conductors makes this cable significantly easier to manipulate in tight junction boxes and complex control panels compared to standard THHN.

• 100% EMI/RFI Shielding: The overall aluminum foil-polyester tape shield, combined with a tinned copper drain wire, provides a total barrier against electrical noise, protecting sensitive digital and analog signals from surrounding high-voltage machinery.

• Rugged Construction: Featuring a flame-retardant, sunlight-resistant PVC jacket, this cable is resistant to moisture, heat, and oils. It is approved for direct burial and use in Class I, Division 2 hazardous locations.

Common Applications

• Multi-Point Sensor Logic: Connecting multiple field sensors or transmitters to a centralized PLC input module in one organized, shielded run.

• Industrial Automation: Ideal for robotic cells and automated assembly lines where the cable must drop from an overhead tray directly to a device-mounted control box.

• Relay and Solenoid Control: Managing banks of small 24V or 120V relays where conductor density and noise suppression are required.

• Process Monitoring: Suitable for telemetry and instrumentation in refineries, water treatment plants, and manufacturing facilities.

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. This prevents ground loops while allowing the shield to effectively drain induced interference. When utilizing the TC-ER rating, ensure the cable is secured and protected from physical damage in accordance with NEC requirements.
