A3281ELHLT-T Overview
Magnetic switches are packaged in Tape & Reel (TR) to prevent damage. To ensure safety, the magnetic switches are packaged in SOT-23W packages. For good performance, the magnetic switches can supply 8mA. The maximum current these switches can supply when they work is 25mA. It is necessary to have a 3 pin for the switches to work. 3 terminations are contained in it. The switches should generally produce a current of 25mA. This switch should have a maximum voltage of 24V when it is operational. In most cases, this switch will supply 12V voltage to ensure relability. In this case, the minimum voltage supplied by the magnetic switch can be 4.2V.
