@Cat I know this thread is ancient, but I have a question about the proprietary 12V 3A power supply cable. Is the pin in the middle truly a ground (since the left pin is already ground), or is it more of a sense pin? I recently purchased a Flir E40bx, and the plug on the camera side is destroyed. I thought maybe I could replace it with another one, but need more specifics for the attempt.
@Fraser: Did you ever figure out what power connector Flir used? I looked at Hirose as you suggested, but no luck so far.
