Mill-max pin information

Here is information on the Mill-max female pins we propose to use for the signal and ground connections to the MDTs. Mill-max does not have complete product information on the web. Phone them at +1 516 922 6000 for a catalog.

The currently favored design is to machine 1.9mm diameter pins as part of the signal cap and ground stand-off on the MDT end plug. Female mill-max pins will be press-fit or soldered into the hedgehog boards to mate with these pins.

Here are two drawings from the Mill-Max web page illustrating the contact technology.
