A1125LLHLT-T Overview
Magnetic switches are packaged in Tape & Reel (TR) for protection against damage. For safety reasons, magnetic switches are packaged in SOT-23W packages. When operating, these switches can output a maximum current of 25mA. There is a maximum current that can be supplied by these switches of 4mA. In order for the switches to function, they have pins 3. Current output by switches should be 25mA in general.
