A3280LLHLT Overview
ldeally, the magnetic switch should be packaged in the Tape & Reel (TR) for protection against damage. As a safety precaution, the magnetic switches are packaged in SOT-23W packages. A magnetic switch with good performance can deliver 8mA as its maximum current. In operation, these switches can output a maximum current of 25mA. Switches require 3 pins to work. This document has 3 terminations. There should be 25mA current output from the switches in general. It should supply a maximum voltage of 24V when it is functioning. For reliable performance, this switch usually provides 12V voltage. It is possible for this magnetic switch to provide a voltage of 4.2V at its minimum.
