This magnetic sensor can measure minute magnetic changes. Magnetic field changes on the order of 1/50000 of geomagnetism can be detected. It removes static magnetic field signal components such as geomagnetism and detects AC signals only.
It can be used to detect iron-based minute foreign matter in the order of 100 μm.

DH single and multipin layouts
Here are examples of how to connect to a single-type MI-CB-1DH-S-A (B) and a multi-type MI-CB-1DH-M-A (B).
Note when using multiple DH in parallel
Notes on using more than one MI-CB-1DH
If several single-type nanotesla sensor MI-CB-1DH-S are used side by side, the respective sensors will interfere with each other, resulting in malfunction. Therefore, when two or more sensors are used together, select a MI-CB-1DH-M, which does not have an oscillator, and connect to a common oscillator MI-CB-1DH-OSC. When purchasing a multi-type MI-CB-1DH-M, an oscillator is supplied. (We also sell it.)
