Draw-wire sensor - Sensor de Fio ou potenciômetro retrátil

@henriqueadm , your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project :wink: See About the Installation & Troubleshooting category.

Have you managed to get a datasheet of the sensor; unfortunately the site is in Portuguese and I can't find a link to it.
