What is the 10-Pin Auxiliary Adapter?

The AVKNGAU9R is a 10-pin MS3112E12-10P auxiliary adapter which connects a Bendix King KNG portable handheld radio to a MS3112E12-10S port on the flight panel of a helicopter.  The adapter allows the BK Radio KNG Handheld to integrate with the on board radio system on the helicopter. These aviation adapters use a barrel style connector and includes a BNC RF antenna connector.  

Works with the following Bendix King Radios: 

  • KNG P150 and KNG P150 Command Series Radios
  • KNG P150S Series Radios
  • KNG P400 Series Radios
  • KNG P400S Series Radios
  • KNG2 P150 and KNG2 P150CMD Series Radios

Why Choose the AVKNGAU9R?

The 10-pin AUX-FM adapter allows for simple interfacing of a BK KNG series portable radio with aircraft AUX-FM audio systems. No need to make a custom set up for a new radio when you can get a pre assembled and tested auxiliary adapter ready to plug and play.  


Note: The 10-pin AUX-FM (MS3112E12-10S) port is commonly found in US Forest Service aircraft.  Not all aircraft use a 10-pin MS3112E12-10P auxiliary plug.  For Cal Fire 6-pin MS3126F10-6P AUX-FM see AVKNGAU9R6.  Built using the USFS OAS A-17 configuration standard.

*Flight helmet headset adapters are also available, see AVKNGFH9R

Quick and Easy

We have had to make out own patch cords in the past which can be a total pain. This Adapter makes it quick and easy to plug our handheld radios into the flight panel and keep in communications with the ground.
