hiii,
I am using DRV5053CA hall effect sensor in my application to detect a magnet in my application.
I know the magnetic flux density is a vector quantity and it changes acccording to the poles of the magnet detected.
but i want to know the maximum detectable range means distance by the sensor . anyone please help me.
regards,
Shiva
Hello Shiva,
The sensitivity of the DRV5053CA is +23 mV/mT (typ). You can use the Design Tool on the right side of the DRV5053 product page to determine the strength of the B field a certain distance away from a magnet. If you put in the material and dimensions of your magnet, you can use this to determine the suitability of the application.
For example, I'll use the default magnet material (Ferrite) and shape (15x15x7mm) in the tool. To find out at what distance the DRV5053CA would saturate, experiment with distance values until B = Bsat = 35mT. In this case, Bsat was achieved at a distance of 8.2mm from the sensor.
