A method is described whereby assemblies comprised of similar appearing, but physically different, parts can, on an assembly line, be determined to have the correct part content and the correct part orientation. The method is aimed at automatic assembly with no manual intervention and eliminates secondary parts, such as labels which are costly to apply. (Image Omitted) Referring to Figs. 1 and 2, an assembly (in this case a logic cage) comprised of two halves is equipped with integrally cast or molded rectangular notches opposing one another on each of the respective halves in the assembly. Similar appearing, but physically different, cage halves (that assemble to make different logic cages) are likewise equipped with notches which are, however, located in different positions (refer to Fig. 3).
