A1102LLHLT-T Overview
Magnetic switches are packaged in Tape & Reel (TR) to prevent damage. For safety reasons, magnetic switches are packaged in SOT-23W packages. When operating, these switches can output a maximum current of 25mA. They can supply up to 7.5mA amps of current. The switches are wired with 3 pins in order to function. The file contains 3 terminations. Switches should generally output a current of 20mA. If it works properly, this switch should produce a voltage of 24V. It is normal for this switch to supply 12V in order to perform reliably.
