Linear HALL effect SENSOR 49E

In this comprehensive video, we delve into the functionality and performance of the Model 49E Linear Hall Effect Sensor. The 49E is a widely-used sensor that measures magnetic fields and converts them into a linear voltage output. Our goal is to provide a thorough understanding of its capabilities through a series of tests and analyses.

boa noite professor, não para com o canal, me ajudou muito já :)

Obrigado!

Hello there. Thank you for the explanation. Nicely shown how the sensor works 👍 Since you still have many sensors left I wonder if you would know and if you could show use how to connect two sensors in serie (I Guess) in order to get a limit controller for a linear movement between point A and point B. Thanks for your help.

Hello, actually, it's not usual to use hall sensors in series. Usually, the magnet has both poles on the same side, and this matches with the characteristics of linear movement. Check out this video to get some idea. kzbin.info/www/bejne/h5bLdYOoh9-Mf9k

@@engthink Thank you for your comment. Unfortunately I don't see how your idea could fit into my "proyect". The teave of he slide is linear andl distance I have to cover is aprox 280mm. My idea was to attach a magnet on the moving slide and have two E49 sensors on the rail. One at the start position and the other one at the end position. What do you think is there a way you see how I can do It, without having the hall sensor sitting on the moving parte?

@@Panic853 Now I got what you need. For this distance you need to use a magnetic band attach to slide an a bipolar hall efect sensor will capture pulses . So the amont of pulse will represent the linear movement. If you whant a easy way you can buy the sensor and the magnetic band in aliexpress, try to find by the name linear encoder.

@@engthink Thanks man. I Will look into that. In the meantime I made It to connect two sensors in serie using the out put pin of the first sensor as the Vcc for the second sensor using 5V source. The thing is that I thought to use 3.3V as a source. This makes It again more dificulta, hahaha
