Key highlights
The Dual Row Bi-Lobe® H4 Nano-D’s are a thru-hole mounted, low mass ruggedized connector on .025” (.64 mm) centerlines. The thru-hole tails are spread into a mounting pattern on .050” (1.27 mm) centers, allowing space for annular rings and routing traces. They feature Omnetics’ gold plated Flex Pin contact system conforming to the requirements of MIL-DTL -32139. These durable lightweight connectors are perfect for the most demanding applications and are intermateable with Omnetics’ QPL versions of Military Specification MIL-DTL-32139. They are available with retention screws for a positive lock. These connectors are available in standard sizes ranging from 9 through 65 positions, as well as custom configurations.
