Amphenol’s 2M Micro38999 connector series…the new aerospace standard

7 Jun 2023

Miniaturized modular devices are more commonplace now than ever before, and the key to a useful modular device is how well it interconnects with other devices. In this article, learn how 2M Micro38999 connectors from Amphenol provide an easy, inexpensive, compact way to add versatility to your system.

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.

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.

Ordering Guide for High Speed 2M801

The 2M801 High-Speed Series of connectors is ideal for use in USB 2.0, eSATA and other high-speed databus applications. These connectors utilize Teflon-based inserts that are optimized for high-speed capability. Multiple standard insert arrangements are available. Ideal for applications where space is limited and a high-speed interconnect is needed.

This series features plugs with or without anti-decoupling mechanisms and a Dual-Start ACME thread that provides full mating in 1 1/2 turns. Plugs and receptacles are provided in two different shell styles to accommodate the attachment of the backshell with rear accessory threads or with an integral banding platform. The banding platform allows for the use of EMI shielding attachments and/or overmolding. Contact termination styles include Crimp, PC Tail and Solder Cup.
