The ITT CANNON 057-0777-002 is a connector within the ARINC 600 series, specifically engineered for the air transportation market. It addresses the need for reduced mating forces in rack and panel applications, approximately two-thirds less than previous designs. The connector incorporates low insertion force contacts that are interchangeable with DPX series contacts, enabling retrofit capabilities. It also offers field-replaceable inserts for size 22 and power contacts, accommodating up to 800 size 22 contacts. Available with crimp, coax, power, printed circuit, and wire wrappable post style contacts, it supports standard DPX crimp tooling. The connector is available in both environmental and non-environmental versions, and features polarizing posts that are removable from the mating face.
