Nano Circular Series Data Sheet MIL-DTL-32139                                  [ PDF View ]

The World’s Smallest Mil-Quality Circular

The Nano Circular Series utilizes Omnetics' rugged and reliable Flex-Pin contact system. Spaced on 25 mil (.64mm) centerlines and a 9.0 mm mated length, these connectors are the smallest Mil-Quality circulars available today. Extremely small outer diameters range from .122" (3.1 mm) to .217" (5.5 mm). With the ability to withstand high shock and vibration while maintaining their electrical integrity, these connectors are ideal for the most demanding applications. Gold plated contacts are polarized and shrouded by our unique Liquid Crystal Polymer housing, making these connectors capable of over 2,000 mating cycles. 6, 11, 16 & 28 positions housing sizes are available in pre-wired and solid straight tail versions. Elaborate wire harnesses, flex termination, over molding and custom shells are all available upon request.
