DATA SHEET
MRSS31U
Micro power Built-in IC ultra-minimum MR sensor
MR Sensor
FEATURES
*Micro power (15µW(typ):Vcc=3V) 1.Dimension (Unit:mm)
and High-sensitivity(2mT(typ))
(suited for battery-operation)
*Ultra-small size
MR(Magneto-resistance)sensor
* Volume and mounting area are 50%
smaller than MRSS22L.
* Height is about 4mm lower than
MRSS22L.
*Operating in one way magnetic field
*Operating with independent pole
(easily manufacture)
*Superior Temperature stability
*Lead free goods
