1.6/5.6 (L9) Connectors for Flexible Cable are compact RF coaxial connectors designed for termination onto flexible coaxial cable, forming jumper leads, patch cables, and interconnecting cable assemblies used in video, CCTV, and telecommunication transmission systems. Built on the 1.6/5.6 DIN interface standard, this connector series maintains stable 75Ω impedance while accommodating the bend radius and routing flexibility required in cable assembly applications. 1.6/5.6 (L9) Connectors for Flexible Cable are commonly used between distribution panels, transmission racks, and terminal equipment where a flexible, repeatedly routable cable connection is required rather than a fixed panel termination.
Compared with bulkhead or flange mount connectors, 1.6/5.6 (L9) Connectors for Flexible Cable are designed with a clamp or crimp termination structure that accommodates the braided or stranded outer conductor of flexible coaxial cable, allowing the finished cable assembly to bend and route around equipment without stressing the connector-cable joint. Contact components in this category are typically machined from brass or phosphor bronze and finished with nickel or gold plating to meet the conductivity and durability requirements of repeated cable handling and installation.

Application Scenarios and Selection Points
1.6/5.6 (L9) Connectors for Flexible Cable are applied in CCTV surveillance jumper cables, CATV distribution patch leads, video transmission interconnects, and telecommunication test cable assemblies where routing flexibility and repeated handling are required. When selecting a connector from this category, the following points are recommended for confirmation:
- Cable type and diameter — flexible coaxial cable specification, matched to the connector's clamp or crimp dimensions
- Termination method — clamp or crimp, selected according to assembly process and cable construction
- Impedance matching — 75Ω configuration confirmed against the video or data transmission system requirements
- Plating material — nickel plating for general durability, gold plating for improved conductivity and corrosion resistance
- Cable assembly length and routing — considered for installation within distribution panels and equipment racks

FAQ
Q: What is the difference between connectors for flexible cable and bulkhead mount connectors?
A: Connectors for flexible cable are terminated onto cable ends using clamp or crimp methods and allow repeated routing, while bulkhead mount connectors are fixed to a panel and remain in a stationary position.
Q: What is the typical impedance of these connectors?
A: 1.6/5.6 (L9) Connectors for Flexible Cable are typically configured for 75Ω impedance, matching common video and CATV transmission standards.
Q: Are these connectors suitable for high-density cable assemblies?
A: Versions designed for thin, small-diameter flexible cable are suited for high-density, multi-channel cable assembly applications.
Q: Can termination dimensions be customized for specific cable types?
A: Clamp and crimp dimensions can be adjusted according to the specific flexible cable diameter and customer drawings.
