I happened to be browsing through some product literature the other day. Like many of us, I took a quick skim, look at the images, scanned a datasheet, and that's about it.
But I stopped on this one because it has a 100G Shock resistance or a 10G vibrational force for a period of 6 hours. I looked it up: humans can't handle more than 5/6Gs briefly. So, I was curious to see how it was designed or different from other connectors.
Most industrial connector systems use 2 points of contact, which is enough for stationary equipment. These contacts are resistant to a certain amount of vibration. However, this connector uses a 3-fingered Beryllium Copper open crimp contact. The additional contact finger gives improved vibration resistance in any direction. The added contact means each contact beam needs less normal force and puts less strain on the beams and decreases wear.
It's called the M225 Series Connector by Harwin. You can learn more by clicking here
