A3212ELHLT-T Overview
ldeally, the magnetic switch should be packaged in the Tape & Reel (TR) for protection against damage. In order to protect the switches from damage, they are packaged in SOT-23W packages. When these switches are working, 1mA is the maximum current they can output. It is possible to supply 2mA current with these switches. It is necessary to have a 3 pin for the switches to work. There are 3 terminations in it. There should be 1mA current output from the switches in general. It is normal for this switch to supply 2.75V voltage for reliable operation. This magnetic switch can supply a voltage as low as 2.5V. When the magnetic switches are operating, they could supply 2.75V.
