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 is used as an iron-based minute foreign matter detection sensor.

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.)
Removing AC coupling
Although MI-CB-1DH is designed to output only the AC component of the sensed magnetic field, you may want to output the DC component as well. In doing so, you can stop interactive bonds by modifying them as follows.
