Sunkye MIL-DTL-83513 Micro D sub connectors fitted Twist Pin Contact System, offer
outstanding mating performance, provides a superior wire attachment which translates to lower contact resistance—and it does so under extreme conditions of vibration, shock, and high heat. With 1.27mm contact spacing (pitch size), which is half the size of D-sub connectors allow for 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 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.
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.
