Overview

The ALS31313KLEATR-JOY is a 3D linear Hall effect sensor designed for high-resolution X, Y, and Z-axis magnetic field measurement. This AEC-Q100 qualified IC provides 12-bit digital output via I2C and is optimized for low-power operation in battery-powered or automotive human-machine interface (HMI) applications.

Why Choose This Part

The sensor features a configurable low-power duty cycle mode that reduces average current to 14nA in sleep, making it perfect for power-constrained designs. Its 12-bit resolution across wide sensing ranges (up to +/-800mT) allows for flexible mechanical placement and the use of small, inexpensive magnets.

Applications

Joystick and Navigation Controls
Ideal for 360-degree joysticks and thumbsticks where X and Y axes provide position and the Z-axis detects button presses.
Automotive Interior Controls
Used in gear shifters, rotary knobs, and indicator stalks requiring AEC-Q100 reliability and precise movement tracking.
Industrial Robotics
Enables contactless sensing for end-effector positioning and ruggedized operator control panels.
Smart Home Appliances
Provides high-resolution rotary and linear position sensing for sleek, sealed control interfaces.
