The Sunkye family of TwistPin equipped Micro-D subminiature connectors to offer outstanding mating performance,
durability, and minimal contact resistance. Sunkye Micro-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 83513 Micro-D and COTS connectors provide a reliable solution for all high-performance interconnect requirements including high temperature and hermetic applications.
mil dtl m83513 Description
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-sub connectors, represent an excellent solution for saving both space and weight. In addition to a complete range of Micro-D connectors to MIL-DTL-83513, Sunkye' also offers Micro-D PCB connectors and cable assemblies in both metal and plastic bodied versions. With its many possible configurations, Micro-D technology 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 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. It is available:
- In 10 contact arrangements (9 to 100 contacts) for rectangular Micro-D connectors.
