Reference

BIN stands for Basic Identification Number which can be identified by the colored bands on the ends of contacts. Referring to the diagram, the order starts from the very end of the wire barrel end and continues towards the mating end. In this example, the BIN number is 260. Refer to the table below for the color code reference.
