Abstract
The invention is directed to a coding device for electrical assemblies that can be inserted parallel to one another into a module frame and that are contacted via plug devices attached at the back to a wiring backplane. A coding flange having three quadratic openings arranged in a right angle pattern is arranged on the wiring backplane between the guard rails, and a corresponding coding housing likewise provided with three quadratic openings arranged in a right angle pattern is arranged on the assembly next to the plug connector. Coding pins can be selectively oriented within the openings by 90.degree. turns, whereby the free ends of said coding pins are fashioned as tongues having a rectangular cross-section, and the area of the cross-section of the tongues corresponds to half the area of the cross-section of the quadratic openings.
