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.
A non-contact type rotational position sensor comprising a rotor for a sensor mounted on a rotating body to be detected, and a sensitive element sensitive to physical energy generated from said rotor and changed according to a rotational position of said rotor, wherein a rotational position of said body to be detected is detected from an output of said sensitive element, comprising:
An electrically operated throttle device comprising a throttle valve for controlling flow rate of intake air of the internal combustion engine, a motor for driving a throttle shaft for supporting said throttle valve on the basis of a control signal to control a position of the throttle valve, a throttle body provided with said throttle valve internally thereof, a rotor for a throttle position sensor mounted on one end of said throttle shaft, and a sensitive element sensitive to physical energy generated from said rotor and changed according to a rotational position of said rotor, in which a position of said throttle valve is detected from an output of said sensitive element, comprising:
An accelerator position sensor comprising a rotor for a sensor mounted on a rotational shaft of an accelerator pedal, and a sensitive element sensitive to physical energy generated from said rotor and changed according to a rotational position of said rotor, in which a pressing-down position of an accelerator pedal is detected from an output of said sensitive element, comprising:
