Question on Canon circular mil connectors

Factory

Cheers

It depends on the construction of the connector. The older ones from WW-II to 1970's were often easily disassembled with a circlip holding a 2-piece phenolic insulator in the metal housing. Some of these even had notches molded into the phenolic so that a moment with a file could open up a notch to allow repolarizing the connector in the field. Waterproof connectors and some other styles have "rubber" insulators either molded or crimped in, so they can't be altered.

There may be a series where the keying may be modified during the end-user connector build (pinning, backshell, etc.) but I'm not aware of any. Far less likely would be a connector that could be realigned post- assembly. All of the ones we've used have the keys machined into the housing, with a master key at 12 o'clock.

I'm assuming that you're talking about MIL-5015 style connectors.

Dunno about Cannon (note spelling). I've always used Amphenol.

Amphenol can, in most cases be configured, in fact you have to order connectors by the part numbers of the individual components, which is an obstacle course. BTDT.

I guess the Cannon product is similar, but the catalog requires Acrobat 8, so I guess ITT-Cannon won't be getting my business anytime soon :-|

You *must* have the catalog, else you'll not get what you expected, BTDT, too.

--- Factory only anymore, what with elastomeric inserts being glued into their shells with indexing per customer request.

If you've happened onto a bunch of old Cannon plugs with rigid inserts, then my experience is the same as Jon Elson's, and once you remove the circlip securing the two-piece insert into the shell you can easily file away the "cherry" blocking the indexing you want.
