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.
2M801 Features • Heavy Dual-Start ACME Thread • Most durable of the 2M series • Up to 2,000 mating cycles • Two Plug Styles • Ratcheting Anti-Decoupling Plug • Free-Spinning Plug
Why 2M801? 2M801 is generally considered a legacy series and is mostly inactive for new designs. Its successor, the 2M805 series, has a number of important improvements, including a triple-start thread (which reduces the number of turns it takes to fully mate the connectors) and an EMI band (which increases shell-to-shell conductivity and greatly improves signal shielding). You should choose 2M801 if you’re looking to maintain compatibility or interoperability with existing technology or cables.
