A sensor assembly for gear teeth and a geometric positioning method for sensor modules are provided to vertically build two sensor modules in a single circuit board. A sensor assembly for gear teeth includes a housing(22), a first sensor module(26), a plurality of first lead parts, a second sensor module(28), and a plurality of second lead parts. The first sensor module is built in the housing and includes a first and a second Hall effect sensors separated from a first plane and forms a first separation direction placed on the first plane. The first lead parts are extended from the first sensor module parallel with the first plane and each of the first lead parts is bent at a lead part bending angle with respect to an axis parallel with the first direction. The second sensor module is built in the housing and includes a third and a fourth Hall effect sensors separated from a second plane. The second sensor module is placed on the second plane and forms a second separation direction. The second lead parts are extended from the second sensor module parallel with the second plane and each of the second lead parts is bent at a lead part bending angle with respect to an axis parallel with the second direction. |
