By its very design, the Micro-D 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 connectors, 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 connectors to 83513 micro D connectors, 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.

The Twist Pin contact by its design and performance enables the system to meet the most severe requirements – often significantly more so than stipulated in the MIL-DTL-83513 and MIL-DTL-32139 standards. The male Micro-D contact is made up of 10 strands of beryllium-copper and copper alloy twisted together, welded then bumped. These sprung strands are in fact compressed during insertion into the turned female contact and therefore a high number of electrical contact points are permanently assured while retaining flexibility and ease of insertion/ extraction.  The bulged point will be compressed inside the socket during insertion. Insertion and retention performance of the twist pin and socket mated pair. Both socket contact chamfer and twist pin hemispherical radius contribute to ensuring adequate insertion even in case of misalignment.

Range of Micro-D connectors 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.
