Position sensors are available in single-turn and multiturn configurations. Single-turn position sensors measure a single rotation, while multiturn sensors measure multiple rotations, even in the absence of power. The ADI MagIC+ current sensors utilize AMR platforms to enable innovative sensing technologies and deliver radical improvements over incumbent core-based Hall technology or CT-based solutions.
