TLE4923傳感器變送器的磁性傳感器-開(kāi)關(guān)（固態(tài)）規(guī)格書PDF中文資料

TLE4923屬于傳感器變送器的磁性傳感器-開(kāi)關(guān)（固態(tài)）。由英飛凌科技股份公司制造生產(chǎn)的TLE4923磁性傳感器 - 開(kāi)關(guān)（固態(tài)）該系列產(chǎn)品使用固態(tài)技術(shù)來(lái)檢測(cè)是否存在超過(guò)某個(gè)特定幅度和/或標(biāo)示的磁場(chǎng)，并提供指示是否存在此類磁場(chǎng)的雙態(tài)輸出。它們與磁簧開(kāi)關(guān)以及線性或羅盤型固態(tài)器件不同，前者通過(guò)使用移動(dòng)機(jī)械部件來(lái)提供類似的功能，后者提供指示所施加磁場(chǎng)的強(qiáng)度和/或方向的可變輸出。

Dynamic Differential Hall Effect Sensor IC

The differential Hall effect sensor TLE 4923 is compatible to the TLE 4921-3U, except for having a 2-wire interface. The TLE 4923 provides high sensitivity, a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. TLE 4923 is particularly suitable for rotational speed detection and timing applications of ferromagnetic toothed wheels such as in anti-lock braking systems, transmissions, crankshafts, etc. The integrated circuit (based on Hall effect) provides a digital signal output with frequency proportional to the speed of rotation. Unlike other rotational sensors differential Hall ICs are not influenced by radial vibration within the effective airgap of the sensor and require no external signal processing.
