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 direction. MR series are designed to be ON-state (L-level output) when the horizontal direction 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 direction magnetic field, it has not influence of the reverse-magnetic field. And also, MR series detect the vertical direction 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. Front view

Position B Output level = Low → High
Position A Output level = Low
Position C Output level = High
In case MR series is used for fold type cellular phone, IC sense the conditions of opening and shutting of the cover by detection of the magnetic flux according to the distance between IC and magnet. 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). Moving direction

In the detection of the slide type, there are two ways of arrangement of magnetic field detecting direction against moving direction. One is parallel and another is cross with moving direction. In case of parallel positioning of magnetic field with moving direction [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 direction of sensor and magnetic field to be crossed with moving direction of cover [arrangement 2].
