ABSTRACT:
A device for associative coding of printed circuit boards comprises a coding member comprising a central longitudinal member, attachment arms and a series of appendages the spacing between which is equal to the spacing between two board guide slideways. The front panel of each board incorporates a coding slot enabling an appendage to pass through it when the latter is aligned with the slot. The position of the coding slot is a characteristic common to all boards of a given family. After a first board is fitted into the subrack only other boards of the same family can be connected into the part of the subrack fitted with the coding member. This prevents the insertion into the same subrack or subrack compartment of boards from different and incompatible families although for a same product type and having the same functionality.
