A3281ELTTR-T Overview
A protective Tape & Reel (TR) package surrounds the magnetic switch to protect it from damage. Magnet switches are packed in TO-243AA packages for safety reasons. As a maximum current, magnetic switches can supply 8mA. In operation, these switches can output a maximum current of 25mA. Switches are operated by 4 pins. The document has 3 terminations. The switches should typically output 25mA of current. It is normal for this switch to supply 12V in order to perform reliably.
