Comparison Of Different Inductive Position Sensor Providers

The main inductive position sensor providers are: Melexis Renesas Microchip TI Onsemi AMS These companies typically offer two types of inductive position sensors: High-speed ICs (usually for rotary applications with SIN/COS output) Low-speed ICs (for linear or reduced range-of-motion applications with ANALOG/SENT/SPC/SPI/PWM outputs). In this comparison, we will focus on high-speed IPS. The comparison parameters […]

Why Is PCB Design Crucial For Inductive Position Sensors?

Example with a study case using Comsol AC/DC (source : https://www.comsol.com/paper/modeling-pcb-based-inductive-position-sensors-with-the-comsol-acdc-module-122391) Figure 1. Target surface current distribution and Coil plane magnetic field distribution. Context In a perfect world without mechanical or physical interferences, inductive position sensors (IPS) would operate with minimal error. However, real-world applications always involve non-ideal conditions. Various factors such as additional metallic […]

How To Build Inductive Position Sensor Coils?

Inductive position sensors (IPS) leverage Faraday’s law of electromagnetic induction to convert changes in magnetic fields into electrical signals. As the target object’s position changes, it alters the magnetic flux through a coil, inducing a voltage. An IPS typically includes a transmission (Tx) coil and three receiving (Rx) coils connected to an interface IC. The […]
