MR触感器
利用磁阻效应实现的世界最小级别单芯片MR传感器
概要
以Ni、Fe、Co等强磁性金属为主要成分的合金薄膜随磁场强度的变化改变电阻值，这种现象称为磁阻效应*。MR传感器是利用这种效应的传感器，以非接触方式发挥优异的性能，实现转速检测及位置检测。
*磁阻效应＝Magneto Resistance effect
世界最小级别的单芯片MR传感器
在IC电路上蒸镀MR薄膜是NEC公司的独特成膜技术。应用这项技术，实现了比本公司以往产品大约1/5（体积比）的超小型化，MR传感器是世界最小级别的单芯片传感器。
- 采用3pin 微形模件、平面引线封装的超小型模块。
- 单方向磁场检测型、不受磁场极性影响的高灵敏度传感器。
- 具备高温稳定性
- 电池驱动型（1.6～3.5V等）
- 广范围电压型（3.0～30V等）
- 以高灵敏度（2mT TYP.）动作（25℃）
