.034'' BingSR-034W Tungsten Semi-Rigid Coax Cable 50Ω High Frequency RF Test Probe

The BingSR-034W is a precision semi-rigid coax cable engineered for high-frequency interconnects that demand stable impedance, compact routing, and reliable positional retention. Built with a 1/0.203 mm tungsten wire (HW61) center conductor, PTFE dielectric, and seamless copper tube outer conductor, this cable is specifically designed for probe contact points, test fixtures, and shaped routing inside microwave modules.

Unlike standard copper-core small coaxial cables, the tungsten center conductor is not intended to replace flexible cables — its value lies in enhancing mechanical stability at shaped segments, exposed ends, and probe interface areas. For test interconnects that require maintained probe position, minimal post-installation deformation, and consistent 50 Ω transmission, the BingSR-034W is the purpose-built solution.

• 50 Ω ±1 Ω Impedance Control — for RF, microwave testing, and R&D links with high signal consistency requirements
• Tungsten Wire Core for Superior Positional Stability — high-rigidity center conductor reduces geometric drift at probe tips and shaped segments
• Ultra-Compact 0.85 ±0.025 mm Outer Diameter — fits space-constrained test fixtures, module interiors, and precision electronic structures
• Seamless Copper Tube Outer Conductor — provides a stable coaxial return path for fixed routing after forming
• PTFE Dielectric Insulation — excellent high-frequency performance and thermal stability

• RF Probe Testing — Short-distance 50 Ω signal routing and fixed connections near probe interfaces.
• Semiconductor Test Fixtures — Wafer testing, test sockets, package validation, and internal wiring of test jigs and fixtures.
• Microwave Module Development — High-frequency interconnects inside filters, amplifiers, mixers, antenna feed lines, and related modules.
• Laboratory Measurement Systems — Stable signal transmission within equipment, between modules, or in compact bench-top test platforms.
• Precision Electronic Assembly — High-frequency electronic structures with tight installation space and demanding routing accuracy requirements.
• R&D Prototyping & Validation — Engineering prototypes, small-batch verification, and structural or electrical performance iteration.

• Better suited for position-sensitive test structures — in probe stations, test fixtures, or module interiors, the tungsten core helps maintain pre-set routing geometry
• Reduces post-installation geometric shift — for applications requiring precise control of exposed segments, solder joints, or probe contact positions, a stable center conductor is a critical advantage
• Compact size with controlled impedance — the 0.85 mm OD and 50 Ω ±1 Ω specification enable use in space-constrained high-frequency signal paths
• Reliable fixed precision interconnects — the seamless copper tube outer conductor and PTFE dielectric form a stable coaxial structure optimized for post-forming installation inside modules or fixtures
