Please contact each Web shop for details such as availability of online samples.


This IC, developed by TMR (tunnel magneto resistance effect) technology and CMOS technology, is a magnetic sensor IC that operates with super low current consumption and low voltage.
The output voltage level changes when this IC detects the intensity level of magnetic flux density. Using this IC with a magnet makes it possible to detect the open / close in various devices.
