AVX Corporation has released what it claims to be the first wire-to-board RF coaxial IDC connectors for industrial and automotive applications.

The initial release of the new 00-6791 Series RF Coaxial IDC Connectors is comprised of two small, single-piece solutions suited to different types of coaxial cable and features a patented one-touch coaxial cable termination mechanism that both simplifies the connection process and outperforms competing solutions in terms of size, cost, quality, and performance. The new RF IDC connectors are said to deliver high-quality RF performance that surpasses that of cables soldered directly to a PCB, have a lower component cost and smaller physical size than traditional two-piece RF connectors with comparable performance — measuring down to 10x6.6x3.9mm when seated. They enable easier, less time-consuming, and less costly assemblies than both soldered connections and traditional RF connectors, says the manufacturer.

The series features mechanical bracing for high-strength performance capabilities and is fully compatible with both automated SMT pick-and-place processing and automated lead-free reflow soldering. The new 00-6791 Series RF Coaxial IDC Connectors are also compatible with Bluetooth, GPS, GSM, and WLAN protocols and are rated for 0.5A (depending on the cable), 125VAC operation, 70N of horizontal pull-force, 20N of vertical pull-force, and frequencies up to 6GHz. The termination process for the new RF IDC connectors requires only three simple steps: strip the outer jacket and braid shield, insert the cable with the inner jacket still intact, and manually or automatically depress the insulator cap. This process allows the IDC contacts to pierce the coaxial cable jacket and dielectric, and make direct contact with the braid shield and conductor at the same time. Three windows in the series’ insulator caps reveal the position of the cable, enabling visual confirmation of proper termination, and are compatible with camera-enabled automated cable positioning verification systems. Operating temperatures for the series extend from -40°C to 105°C, with heat resistance during reflow extending to 260°.
