The 2M801-007-16M5-3SA from Amphenol is 2M series, MIL-DTL-38999 series equivalent straight plug with 3 contacts. The 2M series micro-miniature circular connectors can withstand harsh environment conditions. These quick mating connectors have well-proven electrical capability to withstand extreme shock, exposure and vibration. They are designed for interconnect applications requiring high performance and reduced size and weight. These smaller, high density, light weight connectors far exceed the competition in quality and performance levels. The 2M series are superior and versatile connectors designed and tested to mil-spec standards, comparable to MIL-DTL-38999.
