MIL-DTL-32139 Twist Pin Plug Contacts

Super micro connector, Nano D-sub Twist pin technology with 0.635 mm (.025") contact spacing and nano miniature shells. The ideal solution for applications including aeronautics, space, military, medical and off-shore which require extreme miniaturization, reliability, space or weight saving, which widely used in the military area, aerospace, aviation, electrical, ship-building, defense system, etc.

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 the insertion. Make pair insertion of the twist pin and socket to maintain performance. Both socket contact chamfer and twist pin hemispherical radius contribute to ensuring adequate insertion even in case of misalignment.

Sunkye has teamed of twist pin Technology with these custom designed insulators capable of meeting the extreme mechanical and electrical needs in the harshest environments of military/aerospace and industrial applications such as Down Hole Directional Drilling. In addition to circular and rectangular Micro-D connectors and assemblies, Sunkye' CABLE offers Nano-D connectors and jumpers based on the highly reliable Twist Pin contact technology. This is the connector of choice for any application requiring extreme miniaturization combined with high reliability and is used in a variety of fields from military and medical devices to oil and gas exploration. Nanominiature connectors are based on the Nano-D technology with 0.635 mm (.025") contact spacing and nano miniature shells. The performance of Sunkye's Nano-D is fully compliant to the MIL-DTL-32139 specification, giving a guarantee of interchangeability and interminability between suppliers.

As the need for increased miniaturization is becoming even greater, Sunkye' has developed an ultra-high density solution within the existing micro connector size. By putting Nano contacts and Nano pitch spacing into an existing micro shell, extremely compact connectors with very high pin counts can be produced in circular, rectangular, plastic and metal forms. Optimal cabling density is achieved in a rectangular ultra-high density connector made with Nano-D contacts and spacing inside a standard Micro-D shell size. Such a connector can accommodate a very large amount of pins while retaining excellent reliability.

Most electrical and environmental performances are comparable to those of standard Nano-D connectors (250 Vac, 200°C), combined with the robustness and shielding efficiency of the Micro-D metal shell which is compatible with all the hardware types available for Micro-D pigtails. This same process can be applied to most of the standard and special Micro-D range, making it possible to have ultra-high density versions of PCB connectors, wide flange versions, circular, rectangular and combo style versions with a mix of Micro-D and Nano D contacts.
