A1121ELHLX-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. The magnetic switches can supply 4mA as the maximum current for good performance. These switches can output 25mA as the maximum current when they work. The switches have 3 pins for working. In general, the current output by the switches should be 25mA.
