Claims

[Scope of utility model registration request]

A gap spacer made of a non-magnetic material, and two made of a high magnetic permeability material sandwiching the gap spacer from both sides.
a gap forming core provided adjacent to one surface of the gap spacer and formed of a high magnetic permeability material, and a high magnetic permeability core facing the gap forming core in the same plane. One 1/2 core for cross-sectional area expansion made of material is one gear structural unit, and a predetermined number of the above-mentioned structural units are formed, and in mutually adjacent structural units, the 1/2 cores for cross-sectional area expansion are opposite to each other. For magnetic scales, which are arranged side by side, have a side core spacer and a 1/2 core facing it at both ends, and further connect a side core to the outside to form a core of a unit channel. Multi-gap magnetic sensing head.
