ICOM External Antenna Tuner Connector & Stuff

I had some projects to made and those involve external ATU connectors for ICOM radios; I think it's better to have some informations here for anyone looking for them.

Electrical connection for ICOM External ATU 4 pin MOLEX connector:



Thus I searched on various retailers for those connectors and I found them made by Molex.

The connector  case manufacturer's code is 03-09-2041.



The crimp pins manufacturer's code is: 02-09-2103

You can buy them from MOUSER:
