18-4 Shielded VNTC Tray Cable, TFFN/PVC

This 18 AWG, 4-conductor shielded VNTC (Vinyl Nylon Tray Cable) is a dual-rated Type TC-ER industrial cable. Built for precision and durability, it combines the high flexibility of TFFN conductors with a 100% foil shield to protect sensitive control signals from electromagnetic interference (EMI). The TC-ER (Exposed Run) rating allows for efficient installation without conduit in specific industrial transitions.

Key Features of 18-4 Shielded VNTC (TC-ER)

• Exposed Run (TC-ER) Rated: This cable meets the stringent crush and impact requirements of UL 1277. 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.

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

• Comprehensive EMI/RFI Shielding: The overall aluminum foil-polyester tape shield, backed by a tinned copper drain wire, provides a 100% barrier against electrical noise, protecting low-voltage signal integrity.

• Industrial Grade Construction: The flame-retardant, sunlight-resistant PVC jacket is engineered to withstand oils, moisture, and chemicals. It is approved for use in Class I, Division 2 hazardous locations.

Common Applications

• Complex Sensor Interconnects: Ideal for sensors requiring four wires (such as bridge-type transducers or 4-wire RTDs) in noisy industrial environments.

• Stepper Motor & Small Drive Leads: Providing shielded power and control to small motors and actuators where noise leakage must be contained.

• Industrial Automation & Robotics: Consolidates multiple signal or power legs into a single, highly flexible shielded run for automated machinery.

• Process Control Logic: Used for 24V DC or 120V AC control circuits where a dedicated ground or neutral is required alongside signal conductors.

Conductor Identification: E2 Color Code

Technical Specifications

• Conductor Size: 18 AWG

• Number of Conductors: 4

• Conductor Material: Bare Annealed Copper (Stranded)

• Insulation: TFFN (PVC with Nylon Skin)

• Shielding: Overall Aluminum Foil-Polyester Tape (100% coverage)

• Drain Wire: Tinned Copper

• Jacket: Flame-Retardant, Sunlight-Resistant PVC (Black)

• Ratings: 600V | 90°C Dry | Type TC-ER

• Compliance: UL 1277, UL 66, IEEE 1202, RoHS Compliant

Technical Note: To ensure effective shielding, the tinned copper drain wire should be connected to a ground bus at the source end only. Terminating the drain wire at both ends can create a "ground loop," which may introduce electrical interference rather than eliminate it. Ensure the cable is secured and protected from physical damage in accordance with NEC requirements when utilizing the TC-ER rating.
