A3281ELTTR-T Overview
The magnetic switch is packaged in Tape & Reel (TR) to protect it from damage. It is necessary to put the magnetic switches into TO-243AA packages in order to ensure their safety. For good performance, magnetic switches can supply 8mA as their maximum current. If these switches are operating properly, they can output 25mA as their maximum current. Switches are operated by 4 pins. The file contains 3 terminations. The switches should normally output 25mA current. When this switch is in a reliable operating state, it typically supplies 12V voltage.
