LEMO connector identification

We recently ordered new LEMO connectors, FGJ.2B.319.CLLD72 to manufacture new cable assemblies. These connectors have two keys. We also need to obtain identical connectors, with the exception that these need just one key. Can anyone help with the correct LEMO part number please.

Hello dennis2,

Welcome to the DigiKey TechForum.
The third letter (J) is the callout for the Alignment Keying. The J will have 2 keys. The only callout for 1 key, is the letter G.
So the same connector with only 1 key, would be FGG.2B.319.CLLD72, but we do not carry that part number.

Thanks David

That makes thing a lot cleared now.
