Overview
SS345PT/SS445P 传感器是小型多功能的数字霍尔效应装置，通过永磁体或者电磁体所提供的磁场进行工作，可以对单一的北磁极（或南磁极）作出响应。
这些单磁极传感器采用能满足大量潜在应用的要求的设计。内部的上拉电阻往往能消除对于外接组件的需求，有助于进一步降低系统成本。这些经济的单极传感器非常适合用在简单、大批量、成本敏感的位置和运动感应应用中。
2.7 Vdc 至 7 Vdc 的电源电压范围允许此装置在低电压应用中使用。SS345PT 超小的尺寸所需的 PCB（印刷电路板）空间也更小，从而可在更小的组装中使用。
这些传感器有两种包装形式供选择：SS345PT 采用小型 SOT-23 表面安装型封装，而 SS445P 采用带引脚的扁平式 TO-92 封装。
SS345PT 可用卷带和卷盘（每卷 3000 个）包装；SS445P 为散装（每袋 1000 个）。
