MLX90425
ASIL-B | Analog/PWM | Multipoint characteristic | Temperature -40...+160°C (Automotive)
MLX90425 Melexis Triaxis 3D Rotary 360° Stray Field Robust Position Sensor Gen.III
Cost-effective | ASIL-B | optionally with analog or PWM output | +160°C
The MLX90425 is an ASIL-B capable, absolute measuring 360° stray field immune rotary position sensor with Melexis Triaxis technology based on the Hall effect for cost-sensitive industrial or automotive applications.
The position sensor MLX90425 comes with excellent functional safety as well as electromagnetic compatibility (EMC) characteristics and supports operating temperatures up to 160°C.
It is suitable for non-contact rotary position sensing in automotive, medical or industrial applications. Functionally compatible with previous generation Triaxis sensors.
A simple diametral magnet is sufficient for operation stray field robust 360° applications.
