Allegro offers the most comprehensive transmission speed sensor portfolio on the market. Using leading Hall and GMR technologies Allegro’s selection includes various output interfaces and protocols, SIP packages with magnet and protection component options, and optional ASIL reporting. Our transmission speed sensors are built with decades of system level expertise, providing industry leading vibration immunity and dynamic air gap capability. And our advanced dynamic algorithms compensate for system level disturbances, guaranteeing stable output in the presence of system anomalies.
Our latest offering is a back biased GMR gear tooth sensor IC for larger air gap performance without the sacrifice of industry leading performance capabilities our sensors are known for in transmission applications. And, with Safety in mind, all of our latest transmission speed sensor ICs are designed to ISO 26262—the first in the market.
The ATS19580 is a giant magnetoresistance (GMR) integrated circuit (IC) with integrated protection and a back biasing magnet for sensing speed and direction of rotating ferromagnetic gear tooth targets at large air gaps.
The ATS19520 is an advanced Hall-effect transmissions sensor that uses an integrated back-bias magnet to measure the speed and direction of rotating ferrous targets.
