BKA connectors are the standard for Avionic systems in the Air Transportation market, designed per ARINC 600. They are blind mate connectors available in 3 and 6 gang configurations, accommodating up to 800 low insertion force contacts. Key advantages include field-replaceable inserts for size 22 and power contacts, removable polarizing posts, and compatibility with standard DPX crimp, insertion/extraction tooling. Available in environmental and non-environmental versions, BKA connectors offer various contact styles including crimp, coax, power, printed circuit, and wire wrapable posts. They are designed to reduce high mating forces in racks by approximately two-thirds and are interchangeable with DPX series contacts for easy retrofitting.
