大工作範圍 3.0V ~ 12V﹐ -40℃ ~ 85℃。
反應頻率達 23kHz
高磁場靈敏度。
在 3V 工作電壓﹐磁場靈敏度為 10 mV/ Guass (差動輸出)
在 5V 工作電壓﹐磁場靈敏度為 20 mV/ Guass (差動輸出)
低工作電流 3mA 與 微型化封裝 TO-94, SOT-25。
功能描述:
WSH202 整合磁感元件﹐線性放大器﹐靈敏度控制器與輸出驅動電路在一起。
它能極度準確的追蹤細微的磁場強度變化—通常此一磁場強度變化細微至無法
用正常磁場開關來工作。
WSH202 一般運用於電流偵測﹐齒輪偵測﹐位置偵測與動作偵測等。當作
為磁場強度偵測器時—它可以有效的量測監控系統的工作效能而完全不在乎系
統的負載﹐工作環境與電器干擾。
