NANJING AH ELECTRONICS CO., LTD AH496B,AH3503 SERIES LINEAR HALL-EFFECT SENSORS These Hall-effect sensors accurately track extremely small changes in magnetic flux density changes generally too small to operate Hall-effect switches.
As motion detectors, gear tooth sensors, and proximity detectors, they are magnetically driven mirrors of mechanical events.
As sensitive monitors of electromagnets, they can effectively measure a system's performance with negligible system loading while prov
