2M805 Tri-Start Threaded coupling

2M805 Connectors offer the best EMI and Vibration performance among all the 2M connector series.


  • The series features a Tri-Start thread with 1 turn full mate coupling. An EMI ground strap and shell-to-shell bottoming provide superior EMI shielding.

  • Plugs and Receptacles are provided in two different styles to accommodate the attachment of backshell with rear accessory threads or with integral backshell.

  • The integral backshell allows for use of EMI shielding attachments and/or overmolding.

  • Contact termination styles include Crimp, PC Tail, and Solder Cup with others available upon request.

  • Custom and Filter configurations are available, please consult factory for ordering information.
