Amphenol 2M805 Tri-Start Connector Models and Specifications
What Is the Amphenol 2M805 Series?
The Amphenol 2M805 series is a family of rugged micro-miniature circular connectors developed for aerospace, military and industrial systems requiring MIL-DTL-38999-style performance with reduced size and weight.
The series uses a tri-start threaded coupling mechanism that shortens the mating operation while maintaining secure engagement under shock and vibration. A nickel-plated ground spring improves shell-to-shell electrical continuity and EMI shielding.
According to Amphenol Aerospace, 2M805 connectors are designed to meet the harsh-environment requirements associated with D38999 applications while offering substantial size and weight savings. Standard high-density configurations support up to 130 signal contacts.
Typical applications include:
Aircraft and avionics
Unmanned aerial vehicles
Military communication systems
Ground vehicles
Radar and navigation equipment
Satellites and space-constrained payloads
Rugged displays and computers
Sensor and control equipment
High-speed data systems
Industrial equipment exposed to shock and vibration

Frequently Asked Questions
What is the maximum contact count of the 2M805 series?
The standard signal-contact range supports up to 130 size 23 contacts using the 23-130 insert arrangement.
Is the 2M805 qualified to MIL-DTL-38999?
The 2M805 is designed to meet D38999-style harsh-environment requirements in a smaller package. Qualification status must be confirmed for the exact manufacturer part number.
Is the 2M805 waterproof?
Waterproof and IP67 configurations are available. The actual protection level depends on the exact connector, mating condition, backshell and panel installation.
What is the difference between 2M801 and 2M805?
The 2M801 uses dual-start coupling and is primarily retained for existing-system compatibility. The 2M805 uses tri-start coupling and adds an EMI ground spring, improved shielding and newer configuration options.
Are pin and socket versions available?
Yes. Models are available with male pins or female sockets. A pin connector must be paired with a compatible socket connector.
Does the 2M805 support high-speed data?
Yes. High-speed options are available, but protocol compatibility depends on the insert, contacts, cable construction and termination. It cannot be determined from the contact count alone.
