A1143LLHLT-T Overview
Magnetic switches are packaged in Tape & Reel (TR) to prevent damage. It is necessary to put the magnetic switches into SOT-23W packages in order to ensure their safety. In order to function well, magnetic switches should be able to supply a maximum current of 17mA. Switches work with 3 pins. It contains 3 terminations. The maximum voltage supplied by this switch should be 24V when it works. In normal conditions, this switch will deliver 12V voltage.
