Overview
SS351AT、SS451A 和 SS551AT 传感器是小型多功能的数学霍尔效应传感器，通过永磁体或者电磁体所提供的磁场进行工作。它们设计为可响应北磁极或南磁极。
这些全极传感器是灵敏度和灵活度很高的器件，采用可满足大量潜在应用要求的设计。SS351AT、SS451A 和 SS551AT 在 25°C [77°F] 时通常的工作点为 85 G。它们可以按照北磁极响应或者南磁极响应的方式工作，所以不需要识别它们的极性，因此更容易安装并降低系统成本。
这些传感器有三种封装样式。SS351AT 为超小型 SOT-23 表面安装型封装；SS451A 为带引脚的扁平式 TO-92 封装，而 SS551AT 则采用 SOT-89B 表面安装型封装。SS351AT 的小尺寸需要的印刷电路板 (PCB) 空间更少，可在更小的组装中使用。其 3 Vdc 能力可以使用在低电压应用中，从而实现节能目标。
SS351AT 可用卷带和卷盘（每卷 3000 个）包装；SS451A 为散装（每包 1000 个装置），SS551AT 则为卷带和卷盘（每卷 1000 个）包装。
