    I have a probe I'm going to repurpose. It's a BWD P90 probe (apparently for a powerscope iia)0. The odd thing about it is that it has a connector that appears to be a push on BNC. However, it doesn't have any cutouts for the lugs. I found the lugs off a BNC socket I had laying about and it fits fine.

    Has anyone seen anything like this before?

    Hi Steve.
    I have PL259 plugs unthreaded, but springy friction contacts to make the connection. They are for fast connect/disconnect in equipment tests or manufacturing/calibration, where you have to plug/unplug hundreds of times during a production work day doing only push-in pull-out.


    I suppose your BNC are also made that way for quick connection without need to fasten/twist in production environments. upload_2019-5-18_19-33-57.jpeg
    There is 'F' type too.
