Connector configurations are available to accommodate even the most demanding and specific applications. Straight and angled connectors are available, as well as a variety of termination styles and impedances to fit specific applications. Reverse polarized connectors are also available. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Amphenol accomplishes this by inserting female contacts into plugs and male contacts into jacks.
