The new SM124-10E
Smart Magnetometer combines a Giant Magnetoresistance (GMR) sensor element
with sophisticated digital signal processing.
An I²C interface provides data as well as an external programming interface.
A digital output provides precise, programmable thresholds:
Unlike awkward, old-fashioned Hall-effect sensors, GMR is sensitive in-plane for
optimal current sensing and easy mechanical interfaces.
Key SM124-10E features include:
• Factory calibrated
• Can detect magnets more than 50 mm away
• I²C and digital threshold outputs
• 7-bit output resolution
• In-plane sensitivity—more usable than Hall effect sensors
• Factory calibrated
• Internal temperature compensation
• Programmable offset and gain compensation
• Optional magnet temperature compensation
• 2.2 to 3.6V supply
• Ultraminiature 2.5 x 2.5 x 0.8 mm TDFN package

evaluation board with:
|
| -
|
an SM124-10E sensor.
|
| -
|
a microcontroller connected
to the sensor via I²C.
|
| - |
a current-carrying
trace under the sensor for evaluating as a current sensor.
|
| •
|
A
powerful, intuitive graphical user interface.
|
| •
|
Simple
software installation.
|
| • |
Flexibility
to power from USB or external power supply.
|
| • |
Isolated
USB interface for safety and low noise.
|
| • |
USB
cable to connect the Evaluation Board to a computer.
|
| • |
A
small ceramic magnet for evaluating as a proximity sensor. |
Here’s a live demonstration of the kit:

Self-Contained
SM124 Programmer
The new SM124 Smart
GMR  Magnetometer
can be programmed for whatever magnetic threshold you want, and a ridiculously
simple I²C interface lets you program it from a microcontroller.
And we also offer a self-contained board that lets you set the threshold with
thumbwheel switches. No computer needed.
There is a pushbutton for rezeroing, and miniature thumbwheel switches for programming
threshold and hysteresis. The module is powered by a small wall-mounted power
supply (included).
Jumpers allow the SM124-10E to be disconnected from the rest of the board so the
board can also be used as an interface to the customer’s electronics.
SM124 programmers are in
stock for immediate delivery.
Smart
Magnetometer Socket Board
The AG954-07E provides
a socket for easy programming and prototyping of TDFN6 devices without soldering
and unsoldering.
The custom socket is compatible with NVE's 2.5 mm x 2.5 mm TDFN6 package parts
(-10E suffixes), including the new SM124-10E Smart Magnetometer:
A 0.1"-spaced header
provides for connections to the sensors, and a row of 0.1"-spaced through-holes
allows for auxiliary parts such as a decoupling capacitor or an LED for the Digital
Output pin.
The board is 1.5" x 2" (38 mm x 50 mm), and uses brass
hardware to minimize magnetic interference with the socketed sensor.
