摘要
The invention relates to a non-contact type rotational position sensor. A rotor (31) (a permanent magnet) is mounted on a rotational shaft (40). A Hall IC (6) is interposed between an upper stator (4) and a lower stator (2) which are magnetic plates. The Hall IC (6) is sensitive to magnetic flux density which varies according to a rotational position of the rotor (31). In a housing (1) incorporating the rotor (31) and the Hall IC (6) is provided integrally a connector (7) provided with an external connection terminal. Conductors (7) for connecting external connection terminals and input/output terminals of the Hall IC (6) are embedded into the housing (1) by insert-molding. One ends of conductors (7) are exposed at a fixed position where the input/output terminals are present. The terminals of the Hall IC (6) are guided by a guide (10) and joined to the one ends of conductors (7).
