A3281ELT-T Overview
A protective Bulk package is used to protect the magnetic switch against damage. For safety reasons, the magnetic switches are packaged in TO-243AA packages. A magnetic switch with good performance can deliver 8mA as its maximum current. Switches of this type are capable of delivering 25mA as the maximum current when they are in use. To make the switches work, they have 4 pins. There are 3 terminations in it. It is generally recommended that the switches output 25mA current. In order to provide reliable performance, this switch normally supplies voltage 12V.
