Abstract
Official abstract text for this publication.
A rotational angle sensor and a method for manufacturing the same, and a throttle control device with a rotational angle sensor, which may lower the cost, are provided. The rotational angle sensor includes each sensor IC for detecting a rotational angle of a rotor based on a magnetic field generated between a pair of magnets respectively disposed across the rotational axis of the rotor; each main terminal connected with each connection terminal of each sensor IC; and a holder member for holding each sensor IC and connection portions of each main terminal on each sensor side. A sensor assembly is constructed to form the sensor ICs the main terminals and the holder member into an assembly. A potting material is potted into the holder member.
First claim
