A1121LLHLX-T Overview
Magnetic switches are packaged in Tape & Reel (TR) to prevent damage. To ensure safety, the magnetic switches are packaged in SOT-23W packages. When they work, these switches can output 25mA as their maximum current. Switches of this type can deliver currents up to 4mA. Switches work with 3 pins. In general, the current output by the switches should be 25mA.
