Amphenol’s 2M Micro38999 Connector Series… The New Aerospace Standard
Averaging less than half the size and weight of their 38999 ancestors, Amphenol’s 2M Micro38999 series are an easy and inexpensive way to take weight out of your system. 2M meet or exceed most environmental and performance requirements listed in MIL-DTL-38999, so modernizing your equipment doesn’t mean sacrificing ruggedness. With almost 2,000,000 configurations in every termination style and a full complement of accessories available right out of the catalog, customization has never been easier. Smarter, faster and smaller: Amphenol’s 2M… the only connector you’ll ever need.
2M803 Features • Bayonet Coupling • Quickest turn-mating of the 2M series • 1,000 mating cycles • Lightest of the 2M series
Why 2M803? 2M803 connectors are very light; and their fast, sure-mate bayonet coupling make them the perfect choice for light duty applications that require frequent disconnect. Their small size and easy decoupling also make them the connector of choice for customers who have hard-to-reach panels. Unlike their other 2M counterparts, 2M803 connectors are not rated for immersion, and are recommended for general purpose connections that will not be exposed to the elements for very long.
