Amphenol 2M801 Micro Connectors 2 to 55 Contacts
What Is the Amphenol 2M801 Series?
The Amphenol 2M801 series is a family of micro-miniature circular connectors designed for harsh-environment interconnect systems where a conventional MIL-DTL-38999 connector may be too large or heavy.
Its heavy-duty dual-start ACME threaded coupling mechanism provides secure engagement while requiring approximately 1.5 turns for complete mating. Depending on the configuration, 2M801 plugs can incorporate ratcheting or anti-decoupling features for resistance to shock and vibration.
The series supports multiple shell sizes, insert arrangements, contact counts and termination styles. Available configurations include cable plugs, wall-mount receptacles, jam-nut receptacles and high-speed versions.
Typical applications include:
Avionics and aircraft electronics
Military communication equipment
Radar and navigation systems
Unmanned vehicles
Small satellites
In-flight entertainment systems
Soldier-worn equipment
Rugged displays and portable electronics
Space- and weight-constrained industrial equipment
Amphenol currently positions 2M801 primarily for existing installations and interoperability with established 2M801 cables and equipment. For a new design without compatibility restrictions, the newer 2M805 tri-start series should also be evaluated.

Frequently Asked Questions
Is Amphenol 2M801 a MIL-DTL-38999 connector?
The 2M801 family is designed as a compact, military-style harsh-environment connector and is frequently described as comparable to MIL-DTL-38999 Series III. However, a commercial 2M801 part number should not automatically be treated as a QPL-listed MIL-DTL-38999 part. Qualification status must be verified for the exact model.
Is the 2M801 series discontinued?
Amphenol describes 2M801 as a legacy series, but numerous configurations remain available through authorized distribution and factory ordering. It is still relevant for replacement, maintenance and installed-base compatibility.
Can a 2M801 pin plug mate with a pin receptacle?
No. A pin contact arrangement normally requires a corresponding socket-contact connector. Confirm the “P” or “S” contact code on both part numbers.
Are all 2M801 connectors IP67 or IP68?
No. Environmental ratings depend on the exact shell, mounting, sealing arrangement and termination. Some standard configurations are listed as IP67, while specialized configurations may be listed as IP68. Always verify the individual part drawing.
What is the difference between A, B and C rotation?
These letters identify alternate key orientations. They allow otherwise similar connectors to be mechanically polarized so that an incorrect cable cannot be connected to the wrong equipment port.
How do I request a quotation for an Amphenol 2M801 connector?
Provide the complete manufacturer part number, required quantity, target delivery date and any documentation requirements. If the complete code is unavailable, provide the connector style, number of contacts, pin or socket requirement, mounting method, shell finish and key orientation.
