    • PROBLEM TO BE SOLVED: To provide a position sensor that can be made active by approach to an excitation part but cannot be made active by an external magnetic field.
      SOLUTION: A set comprises the position sensor 11 and the excitation part 13. The position sensor 11 has three reed contacts 27, 28, 29 that are arranged in a triangular arrangement and are made parallel one another. The two first reed contacts in them are used to detect an excitation magnetic field doubly. The third reed contact 29 is used to generate an error signal when the sensor is made active by an external magnetic field. The excitation part 13 has three permanent magnets 17, 18, 19 arranged in a triangular arrangement equivalent to that of the reed contacts, and their polar axes are made parallel each other.

    • 要解决的问题:提供一种位置传感器,其可以通过接近激励部分而被激活,但是不能被外部磁场激活。

      解决方案:一组包括位置传感器11和激励部分13.位置传感器11具有三个布置成三角形并且彼此平行的三个簧片接触件27,28,29。 它们中的两个第一簧片触点用于双重检测激励磁场。 当传感器被外部磁场激活时,第三簧片接触件29用于产生误差信号。 励磁部分13具有三个布置成与簧片接触相同的三角形布置的永久磁铁17,18,19,它们的极轴彼此平行。 版权所有(C)2008,JPO&INPIT
