The nano miniature connector (a.k.a. “NANO”) is a little known connector size that has been around for more than 25 years. It was typically used in the high-end military/defense market. The original design was based loosely around the more familiar micro miniature (a.k.a. “Micro”) connector line. The Micro connector is designed with .050” contact centers (pitch) whereas the NANO has .025” centers. The 2 to 1 ratio in contact pitch equates to a 4 to 1 ratio in total space required.

The NANO requires only 25% of the space that is typically needed for a Micro connector with the same number of contacts. The electronics world is getting smaller and smaller so this feature becomes quite necessary.
