*1The characteristics are the values at a typical (Typ.) supply voltage (V) and at an air temperature of 25°C.
*2The sensitivity standards for the MRSS29DR-001 for rotation detection applications are based on the duty cycle (ON:OFF), not the ON/OFF sensitivity. When the magnetic field above a certain level rotates 360° around the surface of the sensor, a stable duty cycle is obtained. However, if the magnetic force is weak or the center of rotation of the magnetic force does not match the sensor center (and in similar circumstances), the duty cycle may be unstable.
*3MRUS74SD-001・MRUS74SK-001・MRMS791B can set the response frequency by inputting the pulse waveform so that the current consumption can be reduced.
