Description

The ATS657 includes an optimized Hall-effect sensing integrated circuit (IC) and rare earth pellet to create a user friendly solution for direction detection and true zero-speed, digital gear tooth sensing in two-wire applications. The small package can be easily assembled and used in conjunction with a wide variety of gear tooth sensing applications.

? Internal current regulator for two-wire operation

? Variable pulse width output protocol

? Automatic Gain Control (AGC) and offset adjust circuit

? True zero-speed operation

? Wide operating voltage range

? Undervoltage lockout

? ESD and reverse polarity protection

ATS657LSHTN-T屬于傳感器，變送器 > 磁性傳感器 - 開關(guān)（固態(tài)）。Allegro MicroSystems制造生產(chǎn)的ATS657LSHTN-T磁性傳感器 - 開關(guān)（固態(tài)）該系列產(chǎn)品使用固態(tài)技術(shù)來檢測是否存在超過某個特定幅度和/或標(biāo)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(guān)以及線性或羅盤型固態(tài)器件不同，前者通過使用移動機(jī)械部件來提供類似的功能，后者提供指示所施加磁場的強(qiáng)度和/或方向的可變輸出。
