High-accuracy and wide-range linear stroke detection
Issue #01
Solutions
The tri-axis magnetic sensor-based linear stroke detection solution of Asahi Kasei Microdevices Corporation (AKM) provides higher accuracy and wider linear stroke detection range than typical solutions that use single-axis magnetic sensors. This page introduces AKM's recommended products along with their four features.
Features of AKM's Tri-axis magnetic sensors
1. long linear stroke detection
Wider stroke detection
AKM's tri-axis magnetic sensors can detect longer linear strokes than single-axis magnetic sensors.
Demonstration
2. Reduction of mounting error influence
Algorithm Robust to Mounting Error
AKM's tri-axis magnetic sensors are not susceptible to mounting errors, and depending on the required accuracy, the calibration process can be reduced.
Demonstration
3. Less impact of temperature characteristics on the magnet
Less susceptible to temperature characteristics on the magnet
Magnets change in strength as temperature changes, and AKM's linear stroke detection solutions are robust to these changes, enabling more accurate linear stroke detection.
4. Flexible layout
More Freedom in Layout
By taking advantage of the tri-axis feature, linear stroke detection is possible in a variety of layouts.
It can flexibly respond to limited space and severe layout constraints.
Recommended Devices
Multi-purpose tri-axis Magnetic Sensor, AK09973D
AK09973D is ideal for non-contact detection of relative positions, distances, postures and angles with magnets by using it in combination with a magnet.
AK09973D is packaged in 5-pin WL-CSP with 0.4[mm] ball-pitch. Size is 1.18 × 0.78 x 0.55[mm] and it comprises 2 pins for power supply, 2 pins for I²C communication, and one Interrupt output pin.
Application
Ideal for high-precision linear stroke detection of several mm to several tens of mm
