Anyone know offhand what type this connector is? I'm sure I've seen this type of thing somewhere before but can't figure out what it is.

@sen Could be something like the ODU-MAC system. At least the 4pin connector parts look like something ODU or Fischer would build
@fkreiner whoa, I've been a Connector Enthusiast for years and had never heard of ODU! Thank you, I'm definitely going to spec some of these into a project someday :D It sure does look like their kind of thing.
