Description

The A3230 Hall-effect sensor is a temperature stable, stress resistant bipolar switch. This sensor is the most sensitive Hall-effect device in the Allegro?bipolar switch family and is intended for ring-magnet sensing. Superior high-temperature performance is made possible through an Allegro patented dynamic offset cancellation that utilizes chopper-stabilization. This method reduces the offset voltage normally caused by device overmolding, temperature dependencies, and thermal

stress.

A3230EUA-T屬于傳感器，變送器 > 磁性傳感器 - 開關（固態(tài)）。Allegro MicroSystems制造生產(chǎn)的A3230EUA-T磁性傳感器 - 開關（固態(tài)）該系列產(chǎn)品使用固態(tài)技術來檢測是否存在超過某個特定幅度和/或標示的磁場，并提供指示是否存在此類磁場的雙態(tài)輸出。它們與磁簧開關以及線性或羅盤型固態(tài)器件不同，前者通過使用移動機械部件來提供類似的功能，后者提供指示所施加磁場的強度和/或方向的可變輸出。
