(54) Modular magnetic head for scanning magnetized strips or threads


(57) The core of a head for scanning magnetized strips or threads comprises two half-cores (11, 12) elongate in a longitudinal direction and facing one another transversely. Each half-core (11, 12) has a forward end edge (15, 16) parallel to, and magnetically separated from a forward end edge (16, 15) of the other half-core in such a way as to define a longitudinal gap which constitutes the sensitive part of the head. Each half-core (11, 12) is composed of a plurality of modular half-core elements (20) longitudinally side by side with one another. Each modular element (20) has a forward portion (23) defining a section of the forward end edge (15, 16) of one of the two half-cores (11, 12). The forward portions (23) of the modular elements (20) belonging to one (11, 12) of the two half-cores are longitudinally staggered with respect to the forward portions (23) of the modular elements (20) belonging to the other (12, 11) of the two half-cores.
