Welcome to the Allegro MicroSystems' ATS19580LSNx Back-Biased GMR Speed and Direction Sensor product training module. This product has been designed to increase system performance and efficiency without increasing complexity and cost. Improvement in air gap capability has been a growing need with spatially-constrained systems. Allowing more flexibility to the system designers means they can reduce system size and weight; critical to fuel economy, system efficiency, and cost. In addition, the ATS19580LSNx is a fully-integrated solution, easing the burden on the tier suppliers and reducing tolerance stack.
