1. True Triaxial Architecture
Unlike standard coaxial cables that rely on a single shield, our triaxial design features two concentric shields separated by an insulating layer.
Maximum EMI/RFI Rejection: The outer shield is grounded to drain away external interference, while the inner shield carries the return current. This isolates the center conductor completely, ensuring pristine signal quality even in electrically noisy environments.
Guarded Signal Transmission: Essential for preventing ground loops and minimizing leakage in high-sensitivity measurement equipment.
2. Premium Cable Options: TRX316 vs. TRX142
We offer two distinct cable builds to match your exact application needs:
TRX316 (The Flexible Choice): With a slim 1.98mm outer diameter, TRX316 is incredibly pliable. It is the perfect choice for internal wiring inside cramped medical devices, oscilloscopes, or dense patch panels where tight bend radii are required.
TRX142 (The Performance Choice): Slightly larger at 2.79mm, TRX142 utilizes thicker shielding and conductors to deliver significantly lower attenuation per meter. It is the ideal solution for studio broadcast runs, CCTV backbones, or any scenario requiring maximum signal fidelity over extended lengths.
3. Precision Triaxial BNC Connectors
Our connectors feature a three-lug bayonet coupling mechanism that ensures a rapid, positive lock. Internally, they utilize precise solder-cup terminations combined with crimp ferrules to securely anchor the dual braided shields, guaranteeing mechanical durability and consistent 75 Ohm impedance across the connection point.
Broadcast & Professional Video: Interconnecting HD/SD-SDI cameras, vision mixers, and monitors in television studios where zero signal degradation is critical.
Medical Imaging Equipment: Internal and external cabling for Ultrasound machines, CT scanners, and MRI systems that require extreme noise isolation.
Test & Measurement: Connecting sensitive spectrum analyzers, network analyzers, and oscilloscopes in R&D laboratories.
Military & Aerospace: Secure data links and radar subsystems operating in high-interference battlefield or flight environments.
High-Security Surveillance: Preventing signal tapping and ensuring uncompromised video feeds in government and financial institution CCTV networks.
1. Precision Termination Process:
Laser Stripping: We use advanced laser stripping technology to cleanly remove the tough FEP jacket and dual dielectric layers without nicking the delicate silver-plated braids or center conductor.
Dual Crimp & Solder: Both the inner and outer shields are mechanically secured via precision crimping, while the center pin is soldered for optimal electrical conductivity.
100% Electrical Testing: Every assembly undergoes rigorous continuity checks and VNA (Vector Network Analyzer) testing to verify Return Loss and Insertion Loss parameters before leaving our factory.
2. Traceability:
Manufactured under strict ISO 9001 guidelines, each batch is serialized with full material traceability to support your quality assurance documentation.
Protective Packaging: Each triaxial jumper is individually poly-bagged and coiled to prevent connector deformation during transit.
Custom Labeling: Clear, durable labels indicate cable type (TRX316/TRX142), length, and batch code.
Export-Ready Cartons: Packed in reinforced corrugated cartons meeting ISTA 3A shipping standards.
Lead Time: Standard production lead time is 7-10 working days following order confirmation. Expedited options available upon request.
Q1: What is the main difference between a Triaxial BNC and a standard Coaxial BNC?
A: A standard coaxial BNC has one center conductor and one shield. A Triaxial BNC has a center conductor, an inner shield, an insulating layer, and an outer shield. Triaxial cables provide vastly superior protection against electromagnetic interference (EMI) and prevent signal leakage, making them essential for sensitive video and data applications.
Q2: Should I choose TRX316 or TRX142 for my project?
A: If you need to route cables through very tight spaces, inside small electronic enclosures, or require maximum flexibility, choose TRX316. If you are running longer distances (e.g., across a studio floor or between buildings) and need the lowest possible signal loss (attenuation), choose TRX142.
Q3: Are these cables compatible with standard BNC connectors?
A: Physically, triaxial BNC connectors can sometimes be forced into standard BNC jacks, but this is not recommended as it will damage the connectors and ruin the triaxial shielding benefits. They are designed to mate exclusively with other triaxial BNC ports.
Q4: Can you customize the cable length and connector angles?
A: Absolutely. As a direct manufacturer, we offer full OEM customization. We can produce specific lengths, right-angle (90-degree) triaxial BNC connectors, and different jacket colors to meet your exact system integration requirements. Please contact us with your specifications.
In high-stakes environments, signal integrity is non-negotiable. Our Triaxial BNC jumper assemblies combine military-grade shielding architectures with precision manufacturing tolerances. Whether you are transmitting 4K broadcast video or capturing faint medical signals, our TRX316 and TRX142 solutions deliver the noise-free, reliable performance your engineering team demands.
