A1212LLHLT-T Overview
The magnetic switch is packaged in the Tape & Reel (TR) to ensure it is protected against damage. As a safety precaution, the magnetic switches are packaged in SOT-23W packages. The maximum current that can be output by these switches is 25mA. These switches have a maximum current limitation of 7.5mA. Switches require 3 pins to function. It contains 3 terminations. The switches should generally produce a current of 20mA.
