The picture shows the proximity switch circuit composed of the HMC1001 and operational amplifier (AMP04) and light emitting diode (LED). The operational amplifier is used as a comparator here. If taking a magnet with length about 6mm~12mm to close to the HMC1001, when it moves to a certain position, the MR electric bridge`s output voltage would be 30mV to..
