Description of MIL-DTL-32139 Nano D Connectors

MIL-DTL-32139 Nano D sub connectors are ideal solutions for applications including aerospace, military, industrial, medical or off-shore which require extreme miniaturization, space or weight saving and reliability. Sunkye's nano miniature D-sub connectors meet the requirements of MIL-DTL-32139.

The Twist Pin contact of mini electrical connector 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. As a professional nano connector supplier, Sunkye offers top-quality nano connectors for sale. Feel free to contact us for more information.
