Internal Combustion Engine (ICE) Motorcycle & Scooter
The world is demanding better air quality, fuel efficiency and vehicle safety. This means you're designing more electronic controls for engine, transmission and wheel speed in two- and three-wheeled vehicles.
Control of these systems requires robust magnetic sensors and targets that can operate reliably in harsh environments. Our magnetic speed sensors ease compliance with safety (ABS) and combustion engine efficiency mandates. Don't forget to also check out our compact motor drivers and current sensors, highly accurate linear and angle position sensors, as well as our efficient and fault-tolerant LED drivers.
