AS5600 sensor analog output problem in distance

[payel_roy]

Assalamualaikum, I’m using AS5600 Magnetic Encoder Sensor for one of my project. When I setup magnet distance 1 mm in between magnet and AS5600, I got both I2C and analog signal smoothly. But when the distance is 3mm or more I got only I2C value correctly and did not get any analog signal. I study the datasheet and I did not found any logical cause.

I’m using 3.3v in whole system, battery powered. And using the module board so that did not add additional capacitor.

I need the analog signal in between 3 to 5 mm distance. Please suggest a guideline to get the data.

Thank you.

I’ve tried in several distance. Only 1 mm distance provide analog signal. my expecting is to get signal from the sensor from 5 mm distance.

Hi @payel_roy , welcome to SimpleFOC! Unfortunately an air-gap of 3mm is probably too big for the AS5600, or magnetic sensors in general. It’s at the very end of the recommended distance, so as you are experiencing, depending on the magnet, you won’t get a reliable signal. And if this is for motor control, you’ll find that running the motor will further affect the signal quality due to magnetic and electrical interference. So what can you do? One possibility you can try is to use a bigger, st…

I think that was partly the forum software fault, one of his posts needed to be approved (sometimes happens to new user) so got delayed a day. I imagine he reposted when it didn’t show
