When you are looking at circular connectors from Amphenol Industrial Operations, occasionally the suffix LC or (LC) will be added. This is an abbreviation for “Less Contacts,” the code calls out a connector housing with no contacts included.
However, not every single series by Amphenol makes use of this code, so pay attention to what category you’re in when looking over the Circular Connectors (with contacts) and Circular Connectors - Housings (no contacts).
