Top Features

Enhances vehicle system information on wheel movement
Designed for SAE J3016^TM Levels of Driving Automation^TM 3, 4, and 5
Provides distance measurement capability with 5mm resolution (based on a typical 2m tire circumference and 48-pole pair encoder)
Patent-pending algorithms generate the high-resolution events with robustness
The four-event per magnetic cycle mode doubles the number of outputs per magnetic cycle (compared to a normal wheel speed sensor), enabling the use of ring magnets with half the number of poles for potential system cost reduction and increased air gap capability
The eight-event per magnetic cycle mode uses a special protocol that's compatible with AK protocol ECU hardware, paving the way for next-gen ADAS vehicle control
