Distributor Mouser Electronics has introduced the MLX90421 Triaxis 3D magnetic position sensing solution from Melexis, part of the MLX9042x series of position sensors.

Designed for demanding automotive applications, the MLX9042x position sensors deliver reliable performance in harsh environments. The sensors support a wide range of automotive needs, including pedal position sensors, throttle position sensors, transmission position sensors and steering wheel position sensors.

The sensor features ASIL-B functional safety and improved electromagnetic compatibility (EMC).

It supports ratiometric analogue and PWM output modes.

The sensor features a robust operating temperature range of -40°C to +160°C. The MLX90422 sensor supports the SENT (SAE J2716) output mode, and it achieves absolute position sensing with on-chip signal processing.

With stray field immunity the sensor measures absolute position safely and accurately in harsh and noisy environments.

It offers a programmable measurement range and supports ratiometric analogue and PWM output modes. The MLX9046 Triaxis 360° rotary position sensors are available in either a SOIC-8 (DC) single die or an SMP-3 (VE), dual die PCB-less package. The sensor supports both industrial and automotive applications, including powertrain actuators, transmission systems and fuel level gauges.
