Melexis unveils a top notch magnetic position sensor for linear stroke
This new device blends high accuracy for long strokes (up to 30mm), stray field immunity (SFI) and ISO26262 (supports up to ASIL D system integration). This cost-effective solution is ideal for automotive ADAS applications with space constraints such as braking systems (brake rod).
Standalone 3D position sensor for demanding automotive applications
The MLX90423 is designed for use in cost-sensitive automotive applications including powertrain actuators, pedal positioning, fuel level gauges and transmission systems, though also suitable for industrial implementations. It consists of a Triaxis® Hall magnetic front end, an analog to digital signal conditioner,
a DSP for advanced signal processing and a programmable output stage driver (analog, PWM or SENT).
The MLX90423 has superior capabilities in terms of functional safety, absolute maximum ratings (AMR), electromagnetic compliance (EMC) characteristics and supports operating temperature up to 160 °C.
