A1121LLHLT-T Overview
For protection against damage, the magnetic switch is packaged in the Tape & Reel (TR). The magnetic switches are put into SOT-23W packages for safety protection. These switches can output 25mA as the maximum current when they work. The maximum current supplied by these switches can be 4mA. The switches have 3 pins for working. There are 3 terminations in it. In general, the current output by the switches should be 25mA.
