Title:

MAGNETIC ROTATIONAL SPEED SENSOR

Document Type and Number:

WIPO Patent Application WO/1997/004318

Kind Code:

A1

Abstract:

A highly reliable inexpensive direct connector type magnetic rotational speed sensor which is used for detecting the number of revolutions of the rotating shaft of the transmission, etc., of an automobile and whose connector specifications can be easily changed by commonly using a detecting block (2). The sensor is provided with the detecting block (2), a cap (1) which protects the block (2), and a connector block (3) equipped with a flange (3a) having a fitting section of the block (2) and the cap (1) and connector terminals (10) provided on the other side of the flange (3a) and electrically connected to the detecting block (2). The sensor is adaptable to user-side connector specifications by only changing the connector block (3) and the cap (1). Therefore, the increase of the manufacturing cost is suppressed without lowering the reliability of the sensor by commonly using the detecting block (2) which is the key factor of the reliability of the sensor while maintaining the high reliability, and the development lead time of the sensor is remarkably shortened.
