Wire to Wire / Board Connectors

9021 Series

A high-density, multi-purpose, versatile model developed by Kyocera to withstand severe operating environments under high temperature and humidity. These products newly feature a double-spring, multipoint contact which has resistance to atmospheric corrosion as well as a pliable spring characteristic with resistance to vibrations and shocks. Because of hermaphroditic metal to metal contacts, the connectors are free from plastic deformation and the dimensional accuracy is not affected, thus realizing long product life and high reliability. Overloads in insertion and draw outs are prevented with an anti-forcing design. These connectors have outstanding endurance.
