Magnetic sensors capable of measuring minute magnetic changes even in strong static magnetic fields. Only AC signals are detected, eliminating static magnetic field signal components that are stronger than geomagnetism.
The sensor detects only alternating current signals by eliminating the strong magnetostatic signal component of geomagnetism. It can be used to detect minute magnetic fields without the use of a magnetic shield.
It can be used for metal detection near magnetic fields generated by MRI or magnetic metals.

TypeDF single and multipin layouts
Here are examples of how to connect to a single-type MI-CB-1DF-S-A (B) and a multi-type MI-CB-1DF-M-A (B).
Note when using multiple DF in parallel
Notes on using more than one MI-CB-1DF
If several single-type nanotesla sensor MI-CB-1DF-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-1DF-M, which does not have an oscillator, and connect to a common oscillator MI-CB-1DF-OSC. When purchasing a multi-type MI-CB-1DF-M, an oscillator is supplied. (We also sell it.)
