We would like to propose some solutions using AKM's tri-axis magnetic sensor ICs for various issues related to rotation angle detection, stroke detection, and 3D position detection.
Tri-axis Magnetic Sensors
Issue & Solution
We propose solutions based on AKM's tri-axis magnetic sensors that can solve a variety of sensing issues of factory automation equipment.
Detecting rotation angle and stroke with effective use of space
For rotation angle and stroke (distance) detection, the "optical sensor" and "Hall sensor" configurations are often used. However, when using an optical sensor, there are restrictions on the arrangement due to the position between one LED (light source), lens, and light-receiving sensor each. And also when using a Hall sensor, the arrangement of the magnet and sensor is limited because the sensor's magnetic surface is unidirectional.
