Description:
These products are custom-built PCB assemblies for customer specific applications. They typically
contain 20 to 60 analog GMR sensor elements, most often the AA002, AAH002, or AAL002 sensors.
These sensors are mounted on a PCB, most often using Chip-On-Board (COB) assembly techniques,
so that the sensor elements can be placed very close together. In addition, a coil on the PCB is
provided on many of these designs, so that a current can be fed through the coil to provide a magnetic
bias field at the sensors.
In a typical currency detection application, this PCB assembly is positioned approximately 1 mm from
the currency path. The bank note is typically magnetized with a permanent magnet before it reaches
the sensor array. The residual magnetization in the magnetic ink or stripe of the currency is detected by
the sensor array. This information is then analyzed to determine if the currency is genuine. See the
