Product Information
Type DW
This linear output magnetic sensor has a magnetic resolution close to that of the Type DJ and can also measure magnetism at the geomagnetic level. It can be used to detect minute magnetic fields without the use of a magnetic shield.
It can be used for the detection of small ferrous metals in the order of 50 μm, food and apparel products, materials for lithium-ion batteries, ferrous foreign objects in non-magnetic industrial products, and other research applications.

TypeDW single and multipin layouts
Here are examples of how to connect to a single-type MI-CB-1DW-S-A (B) and a multi-type MI-CB-1DW-M-A (B).

Cautionary Statement
Notes on using more than one MI-CB-1DW
If several single-type nanotesla sensor MI-CB-1DW-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-1DW-M, which does not have an oscillator, and connect to a common oscillator MI-CB-1DW-OSC. When purchasing a multi-type MI-CB-1DW-M, an oscillator is supplied. (We also sell it.)
