The DuraNET 20-11 was originally designed in 2014 with two supplier mating connector options. Both Amphenol 2M Series and Glenair Series 801 Mighty Mouse connectors were qualified for use with the J1 and J2 connector interfaces, and they were proven to be intermateable. It has been reported that recent manufacturing/tolerance changes to the Amphenol connectors now make them incompatible with the Glenair Series 801. This incompatibility has now been verified by Curtiss-Wright at the factory.
