Gold 8000 Connectors
The FUJIPOLY ZEBRA® Series 8000 elastomeric connector elements are D-shaped, low durometer silicone elastomer cores around which flat metallic gold-plated conductors are vulcanized in a row parallel to each other. The tips of the metallic conductors are turned upward so that point contact can be effected; in addition, contact is made to the flat area when the connector element is positioned between two printed circuit boards. The point contact will penetrate surface oxides or contaminants which might be present on the surface of the contact pads, thus assuring reliable electrical connection on two planes. Also available are standard board to board assemblies which include connector and holder.
