Abstract
Provided herein is a non-contact type rotational position sensor which is allowed to achieve intensification of parts, miniaturization, simplification of assembly, and higher accuracy. A rotor (a permanent magnet) is mounted on a rotational shaft. A Hall IC is interposed between an upper stator and a lower stator which are magnetic plates. The Hall IC is sensitive to magnetic flux density which varies according to a rotational position of the rotor. In a housing incorporating the rotor and the Hall IC is provided integrally a connector provided with an external connection terminal. Conductors for connecting external connection terminals and input/output terminals of the Hall IC are embedded into the housing by insert-molding. One ends of conductors are exposed at a fixed position where the input/output terminals are present. The terminals of the Hall IC are guided by a guide and joined to the one ends of conductors.
