A1121ELHLX-T Overview
In order to prevent damage, the magnetic switch is packaged in the Tape & Reel (TR). To ensure safety, the magnetic switches are packaged in SOT-23W packages. In order to achieve good performance, the magnetic switches should be able to supply 4mA as the maximum current. Switches of this type are capable of delivering 25mA as the maximum current when they are in use. The switches are wired with 3 pins in order to function. The current output of the switches should, in general, be 25mA.
