Anyone got one of these?

Would be good to see a shot of inside the mating receptacle. i.e. are the pins on the instrument male or female? I think they might be male.

It's using a AMP Universal Mate-n-Lok connector but looks like it has non standard contacts which don't appear in the catalogue. Attachment shows against a standard variety for comparison. There's a couple for sale on eBay at the moment but none show inside that connector!

Gender on instrument must be female as the diameter of the pin is the same as the opening in the receptacle, so if male there'd be no space for the mating contact.

But there is still something weird here. The contacts on the instrument are about a millimeter longer than the standard 19A types, so if I load a Mate-n-Lock receptacle with male contacts it'll mate but not latch as the contacts on the instrument are colliding with the chamfer on the mating pin.

Argh! Seriously!

I think this might be these things - from the "Universal Mate-n-Lok II" catalogue (Attached)

I'll put some on my next Digi-Key order...

Okey dokey. My bits just arrived, and it's a definite confirm, that the instrument does not use the regular "auto store" variety of Universal Mate-n-Lok connector (top, pictured). Do not be tempted to use these. The pins are not long enough to reach to the spring cylinder inside the mating contact, result will be a meltdown given the amount of current this instrument is stated to draw.

The correct contacts are a much larger machined type which crimp with a "Daniels" tool (also pictured). Would also be easy to solder. No chance of fitting these contacts into a regular housing either. They need a different two-piece type.
