320-1067-003 is a polarizing post kit designed for ITT Cannon's ARINC 600 BKAD/E/F series rack and panel connectors. This kit provides polarization positioning components that ensure correct mating alignment between plug and receptacle connectors in military and aerospace systems. The kit includes center posts, left posts, and right posts configured for specific polarization patterns (BKA*1, BKA*2, BKA*3 variants), with dimensions specified in inches and millimeters for precise installation. The polarizing posts feature engagement mechanisms with waveguide details and retaining plates to maintain connector integrity during mating cycles. This kit is essential for applications requiring reliable, keyed connector interfaces in demanding military/aerospace environments where connector misalignment must be prevented.
