Nanominiature DUALOBE® (Shrouded) Connectors & Jumper Assemblies

TE Connectivity's Nanonics D-style rectangular connectors incorporate the DUALOBE polarization scheme. This polarization scheme negates the need for mating guide pins and does not increase the package size. The DUALOBE series of connectors are available in both machined aluminum and molded plastic shells, both in one- and two-row connector housings. Single-row configurations commonly have standard pin counts from 5 to 51, while the higher density two-row configurations have pin counts from 9 to 65. These connectors can be terminated in many different ways. Standard configurations include wires, surface mount, thru-hole, solder cup, “duckbill” and panel mount. Wired harness assemblies and custom configurations can also be accommodated. Such custom configurations include filtered, hermetic, environmentally sealed, and blind mate connectors.

This family of connectors is designed to meet the requirements of MIL-DTL- 83513, with a few size-related modifications. Designed primarily for the military and aerospace industry, the DUALOBE series is especially well suited when high reliability, coupled with reduced size and weight, are serious design parameters. A clear example of this is the use of NANONICS connectors in such applications as smart munitions, missile defense, aircraft communications and UAVs. In addition to the above applications, with the wide temperature range of the DUALOBE connector (-200°C to +200°C), the space and petroleum industries have also found many uses for this connector. The performance and reliability at cryogenic temperatures, along with the low outgassing material properties, has led to an increased usage in space applications. Such applications include nitrogen cooled optics, low and high earth orbiting satellites, telescopes, deep space probes, orbiters and rovers. On the opposite end of the spectrum, the petroleum exploration industry utilizes these connectors for their performance and reliability in downhole environments at temperatures exceeding 150°C.
