High Performance Auto Rotary and Linear Position Sensor
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
The KMA320/321/310 family is designed for high performance applications such as throttle/EGR position sensor, turbo charger/clutch/transmission actuator.
The sensors feature PCB-less design with integrated capacitor. The IC allows user-specific definition of angular range, zero angle position, and clamping voltages.
The settings are stored permanently in a non-volatile memory (NVM). The programmable angle sensor is pre‑programmed, pre-calibrated and therefore, ready to use.
The sensor is developed to ISO26262, and fulfills ASIL B(Analog) or ASIL C(SENT)
