附带使用说明书

除了如何查看MAP以及如何更改显示之外,还记载了各种应用实例。

多种多样的设定

可以针对应用进行磁铁方向、尺寸、磁力特性和电路板方向等各种设定。

各平面显示

可以在XY平面(TOP)/YZ平面(Side)/XZ平面(Front)上进行ON/OFF显示。

介绍模拟工具特点的视频

通过视频介绍模拟工具的特点。
这是比较开闭、滑动、旋转等各种实际接近磁铁时传感器ON/OFF情景与模拟工具上进入检测范围情景的内容。

例如,用仿真工具可以预测AMR传感器从3×1×5mm的钐钴磁铁和初始位置Pa(Xn=0,Yn=0,Zn=3mm)分别沿X和Y方向移动时的OFF位置。

仿真示例1 : 沿X方向移动AMR传感器

将AMR传感器从初始位置Pa移动到Pb并进行以下变更时,将生成如图所示的Map。

  • Pa(0,0,3)⇒Pb(11,0,3)

可以预测AMR传感器将在Xn=约7至11mm之间切换为OFF。

距磁铁中心P0的距离[mm]
Xn Yn Zn
0 0 3
距磁铁中心P0的距离[mm]
Xn Yn Zn
11 0 3

仿真示例2 : 沿Y方向移动AMR传感器

将AMR传感器位置从初始位置Pa移动到Pc并进行以下变更时,将生成如图所示的Map。

  • Pa(0,0,3)⇒Pc(0,11,3)

可以预测AMR传感器将在大约9至14mm之间切换为OFF,
但Yn=4mm附近的颜色不同。

距磁铁中心P0的距离[mm]
Xn Yn Zn
0 0 3
距磁铁中心P0的距离[mm]
Xn Yn Zn
0 11 3

仿真示例3 : 放大AMR传感器的轨迹

向示例2中的Pc移动时,将Yn=4mm附近放大,并进行以下变更时,会生成如图所示的Map。

  • Pa(0,0,3)⇒Pc(0,4,3)
  • 将Y和Z方向的显示倍率分别改为5.0倍

可以预测,在Yn=约3至4mm附近会有一个暂时切换为OFF的位置。

距磁铁中心P0的距离[mm] 显示倍率
Xn Yn Zn X Y Z
0 4 3 ×1.0 ×1.0 ×1.0
距磁铁中心P0的距离[mm] 显示倍率
Xn Yn Zn X Y Z
0 4 3 ×1.0 ×5.0 ×5.0

常见问题

A有。附带的使用说明书里也记述了以下应用实例。
(实例仅有一例。如果磁铁和AMR传感器之间的位置关系共通,则也可将其应用于其他产品。)
  • 滑动检测2(小型、微型开关)
    可用于笔记本PC和数码相机等的小型开关、可穿戴终端的电源开关(易于防水)、小型设备等以几毫米的行程在ON/OFF间切换时的检测。
  • 旋转体的位置检测
    检测自动锁的关闭和打开位置、检测浮动开关(杠杆类型)的液位,以及想以任意角度大小让旋转体的特定角度范围在ON/OFF之间切换时进行的检测。
    除了各种检测示例外,还记载了有关如何调整ON/OFF角度目标值的要点。
A提供能够通过LED亮灯和灭灯确认动作的测试板。首先,单独确认测试板LED的亮灯和灭灯。
然后用双面胶带等将磁铁和测试板固定在要搭载的设备上,然后确认其是否根据动作亮灯和灭灯。
请将其用于引进本产品之前的讨论和验证。

注意事项(请务必阅读)

  • 本工具使用计算磁铁磁力的公式显示简易的ON区域。用公式根据磁铁信息和离开磁铁的任意位置(AMR传感器的位置)信息算出。
  • 如果周围有其他磁铁或螺钉、铁板等影响磁铁的零件,则无法计算。
  • 重要的是要尽量远离其他磁铁和周围造成影响的零件。所谓“尽量”没有参考值,请通过实际设备进行确认。
  • 由于计算值与实际值之间存在差异,因此在批量生产产品之前,请通过试生产和实际设备进行充分验证。
  • 仿真工具和使用说明书可能会不定期变更,例如添加AMR传感器的产品阵容和应用实例。请定期确认版本。
  • 弊公司的AMR传感器仅供民用。请勿将本产品应用于车载产品等要求具备高可靠性的产品,因为这些产品的故障或误动作可能会危害人的生命财产。
  • 请根据功能的重要性、必要性进行充分测试,并实施多重失效保险。
