Ono Sokki MP-981 Magneto-Type Detector Instruction Manual
The Ono Sokki MP-981 is a magneto-type detector utilizing a Hall element to measure rotational speed from ultra-low to high speeds. It features a built-in signal indicator to verify operation and mounting position, ensuring accurate detection even in compact designs. The device is designed exclusively for RPM measurement using strong magnetic materials with specific gear modulus and tooth width requirements.
The manual details the mounting procedures, including the use of a mounting fixture for non-magnetic materials and precise positioning relative to the detection gear. It covers electrical connections, specifying a DC 12V +/- 2V power supply and explaining the connector pin arrangement. Safety precautions are emphasized, such as avoiding contact between the detector tip and the gear and ensuring proper power supply polarity. This manual is written in Japanese.
