Lower the Barrier to Evaluating High-Sensitivity Magnetic Sensors ー Introducing the Type DW Evaluation Kit "EVK-DW" ー
You may be interested in high-sensitivity magnetic sensors, but hesitate to start evaluation because:
"Soldering, wiring, and measurement setup seem complicated."
"It looks like analog circuit knowledge is required."
Many engineers face these barriers before they can even begin testing.
To address this, Aichi Steel has developed EVK-DW, a dedicated evaluation kit for the Type DW MI Sensor, that lowers the barrier to evaluation.
What Changes with EVK-DW?
Conventional MI sensor evaluation typically requires:
- Soldering and wiring of the sensor
- Preparation of power supplies and analog circuits
- Expensive measurement equipment such as oscilloscopes
This process assumes a certain level of expertise and incurs setup costs.
With EVK-DW, the procedure is dramatically simplified:
- Connect the sensor to EVK-DW
- Connect EVK-DW to a PC via USB
- Launch the dedicated software
That's it!
You can evaluate the output of the MI sensor immediately, which significantly reduces time and cost.
👉 Even without handling analog circuits, you can verify the characteristics of a high-sensitivity magnetic sensor.
This is the key advantage of EVK-DW
Overview of EVK-DW
The kit is designed to allow users to fully evaluate the inherent performance of the high-sensitivity sensor.
It can also serve as a reference circuit when integrating the sensor into your own system.
Hardware
- Power supply circuit
- Control circuit for high-sensitivity magnetic sensor (Type DW)
- High-resolution A/D converter
- USB 2.0 communication
(No additional wiring or external measurement equipment required.)
Software (nTScope)
- Real-time display of time-domain waveforms
- Noise spectrum visualization via FFT analysis
- Digital filter configuration
- Data export in CSV format
Example display function:

Who is it for?
EVK-DW is particularly recommended for:
- Engineers who want to quickly test a high-sensitivity magnetic sensor
- Those interested in MI sensors who have been stopped by the evaluation setup stage
Developers considering applications such as foreign object detection, current measurement, or position sensing
Typical Applications
EVK-DW can be used to evaluate and explore applications such as:
- Detection of minute magnetic variations for foreign object inspection
- Characterization of magnetic sensor performance for micro-current measurement
- Position and proximity detection in robotics and automation systems
- Research and development requiring precise magnetic field measurement
- Feasibility studies for high-sensitivity magnetic sensor integration
