Our portable devices would not be possible without proven connector technologies that facilitate miniaturization and connectivity.

Today’s electronics designers are challenged to find the right balance between reliability, suitability, and cost as they specify the components needed to create successful and competitive products. The first step in the search process is to fully understand the application and the requirements that it will put upon the connectors involved.

In some applications, the connector is mated once during production. In others the connector is an integral part of the device, such as in a docking station or a charger. Each of these applications requires a different solution. A correctly applied connector will function better — and last longer — than one that is not well suited for the application. Gathering and using this knowledge is another connector-related challenge for today’s designers.

There are several methods for creating the pins used in connectors. The most flexible is precision machining. This not only provides high levels of quality and reliability, but also offers significant flexibility in terms of design and materials, allowing designers to specify connectors to suit their exact needs. The resulting high-precision pins have a cylindrical geometry and are sometimes called turned pins.

Typical turned pin sizes range from 0.008” (0.2032mm) to 0.25
