AH3194 Gear Speed Sensor 4 General Description AH3194 is a gear speed sensor with self-adaptive adjustment and digital output function. It’s a kind of special automotive gear sensor, but also be suitable for ordinary speed measurement applications. Only one piece Hall element inside the sensor, so no problem of the rotation alignment exists. In addition, it has a 10 bit A/D converter and the logic controller, and another independent 4 bit A/D converter inside it. After two A/D respectively sample and comparison operate to Hall element signals, it can achieve the gear tooth identification. When...

Gear Speed Sensor 10 Magnetic Behavior The sensor is designed for sensing the changes of the magnetic field, so after the magnetic strength changes and reaches a certain value, the sensor will change the output state. After the outer magnetic strength reaches maximum value and then begins to decrease, when the increment absolute value ΔB is above 100Gs, the output state changes from low level to high level; when the external magnetic strength reaches minimum value and then begins to increase, when the increment absolute value ΔB is above 100Gs, the output state changes from high level to low...
