描述 Description

HAL 83x系列是耐用的多功能線性位移和90°以下角度測量。作為可編程輸出低通濾波器，模擬和脈寬調(diào)制輸出讓本產(chǎn)品有了更多的靈活性。系列中的新產(chǎn)品延續(xù)了先行霍爾效應(yīng)傳感器的長期成功，全部本廠生產(chǎn)，并且有汽車級百萬產(chǎn)品零缺陷記錄。主要參數(shù)，比如磁場范圍，輸出格式，敏感性，0磁場輸出電壓（VOQ），及溫度系數(shù)可以通過在非易失性內(nèi)存中對磁電路（線性和二次）編程來進(jìn)行調(diào)整。產(chǎn)品具有帶斬波補(bǔ)償?shù)臏囟妊a(bǔ)償霍爾片，交流直流轉(zhuǎn)換器，數(shù)據(jù)信號處理器，推拉式輸出，裝載標(biāo)定數(shù)據(jù)和數(shù)據(jù)注冊信息的帶冗余和鎖定功能的EEPROM內(nèi)存，一系列EEPROM編程界面，以及在各引腳的保護(hù)裝置。產(chǎn)品可以通過簡單的標(biāo)定來完美調(diào)節(jié)對輸入信號的輸出反應(yīng)和補(bǔ)償應(yīng)用中由磁場、機(jī)械位置產(chǎn)生的差異。這讓產(chǎn)品在全溫度范圍內(nèi)都以高精度工作。對各個(gè)傳感器數(shù)值和EEPROM內(nèi)存的編程可以用一臺個(gè)人電腦和Micronas的工具包輕松完成。
產(chǎn)品被設(shè)計(jì)適用于惡劣環(huán)境下的工業(yè)和汽車應(yīng)用（溫度從?40 °C 到 170 °C）。HAL83x系列有小尺寸含鉛 RoHs TO92-UT封裝，符合 AECQ100要求。
