MRMS611L
High accuracy type MR sensor
MRMS611 is optimal magnetic sensor for applications which require precise control of the detection range.
NEC's original thin film control technology contributed to highly improved magnetic field sensitivity range
as well as temperature characteristics.
[Application Examples]
• Mobile phones, notebook PCs and PDAs requiring high accuracy detection angle
• Slider phones requiring high accuracy position detection
• Applications requiring minimization of temperature dependence
FEATURES
■ MRMS611 is narrow sensitivity type MR sensor which features Min-Max 0.6mT sensitivity range
(includes hysteresis) at ambient temperature.
Operating magnetic field ranges are available in 3 sensitivity level(H, M, L) as shown in the table below.
