A3281ELHLT Overview
In order to prevent damage, the magnetic switch is packaged in the Tape & Reel (TR). For safety reasons, the magnetic switches are packaged in SOT-23W packages. In order to provide good performance, magnetic switches can supply 8mA as the maximum current. If these switches are operating properly, they can output 25mA as their maximum current. Switches have 3 pins for operation. In total, 3 terminations have been recorded. It is generally recommended that the switches output 25mA current. If this switch is functioning properly, it should supply a voltage of 24V. It is normal for this switch to supply 12V in order to perform reliably. In this magnetic switch, 4.2V is the minimum voltage that can be supplied.
