The Sunkye family of TwistPin equipped Micro-D subminiature connectors to offer outstanding mating performance, durability, and minimal contact resistance. Sunkye Microminiature-D Connectors feature high-density micro TwistPin contacts set on 1.27mm centers in arrangements from 9 to 130 contacts. They are available with insulated and uninsulated wire, PCB, solder cup and flex terminations and are supplied as MIL-DTL-83513 or commercial variations. Our mil dtl 83513 connectors and COTS connectors provide a reliable solution for all high-performance interconnect requirements

Description of MIL-DTL-83513 connector

By its very design, the Micro-D type connector system meets all the requirements of robustness, durability, low contact resistance, high current, dielectric strength, shock, and vibration. With 1.27 mm (.050") contact spacing, micro d subminiature, half the size of D type connectors (D series connectors), represent an excellent solution for saving both space and weight. In addition to a complete range of micro d subminiature connectors to 83513 d sub vs micro d, Sunkye also offers Micro-D PCB connectors and cable assemblies in both metal and plastic bodied versions. With its many possible configurations, the technology of micro electrical connectors is perfectly suited to a multitude of systems where weight, miniaturization or signal transmission integrity is paramount: applications benefiting from this technology include everything from missiles and their guidance systems, through oil well drilling tools to medical devices, satellites, and scientific research. For very specific applications such as medical MRI scanners or low magnetic field detection systems, Sunkye has developed a range of non-magnetic connectors using new materials and surface treatments, avoiding ferromagnetic materials. Hermetic micro d connectors are also offered for applications where an enclosure needs to be fully sealed from the outside world.

By the unique design and performance, Sunkye micro d connectors equipped with twist pin contact is enabled to meet the most severe requirements, often significantly more so than stipulated in the mil 83513 and MIL-DTL-32139 standards. The male micro D contact is composed of 10 strands of copper alloy and beryllium-copper twisted together, which is welded then bumped. A high number of electrical contact points are permanently assured while retaining flexibility and ease of insertion/ extraction, because during insertion into the turned female contact the 10 sprung strands are compressed. To keep insertion and retention performance of the twist pin and socket mated pair, the bulged point will be compressed inside the socket during insertion. Meanwhile, the exit of socket contact chamfer and twist pin hemispherical radius ensures adequate insertion even in case of misalignment.

Range of mil dtl 83513 contacts which is covered by the mil dtl 83513 standard is ideally suited to equipment and applications where weight, miniaturization and long term performance are required, so in these aspects it is a model recommended by micro d connectors manufacturers. It is available: In 10 contact arrangements (9 to 100 contacts) for rectangular Micro-D connectors
