APPLICATION INFORMATIONS Detection of magnetic field To operate output switch, the magnetic field should be applied to the sensor with sufficient magnetic flux density and correct. MR series are designed to be ON-state (L-level output) when the horizontal magnetic field is applied in parallel to the marked side of sensor, with sufficient magnetic flux (MOPS or MOPN value) regardless of polarity of magnet. Because MR series detect the horizontal magnetic field, it has not influence of the reverse-magnetic field. And also, MR series detect the vertical magnetic field according to the level of magnetic flux, so that it is possible to apply to not only slide type but also fold type.

In position A, output is L-level (ON-state) because the detected magnetic flux is sufficient. The magnetic flux decrease according to the magnet is moved from IC (Position A B). Then the IC is turned H-level (OFF-state) because the magnetic flux become MRP or less (Position B C). Magnetic field S or N N or S S or N Magnetic field N or S Detection Detection

One is parallel and another is cross with moving. In case of parallel positioning of magnetic field with moving [arrangement 1], the output of IC might be L-level (ON-state) H-level (OFF-state) L-level (ON-state) H-level (OFF-state) due to reverse-magnetic field. To prevent from this malfunction, it is recommended to arrange the detection of sensor and magnetic field to be crossed with moving of cover [arrangement ].
