NTH-series products have excellent bending property, high cable retention, and outstanding phase stability, which provides a Flexible replacement for semi-rigid assemblies. The NTH cable assembly can be bent from the connector’s root to save installation space and replace a rectangular curved connector. The connector’s design adopts welding-free technology, avoiding embrittlement and cracking on the welding position between cable and connector, saving cost and weight. Compared with semi-rigid cable assembly, NTH can be bent flexibly according to site applications, requiring no customized length and bending shape design, thus saving engineering resources and transportation expenses significantly, and reducing the customer’s overall cost.

Features

• Excellent bending phase, amplitude stability
• Stainless steel outer shield, high tensile strength
• Three-layer shielding structure, good insulation
• Stainless steel welding-free connector
• Bending at random and maintaining shape stability

Applications

• Point-to-point interconnection between RF modules
• Interconnection between boards
• Cabinet internal jumper
• Flexible replacement for semi-rigid assemblies
• Radar and Electronic Warfare Systems
