A3281ELT Overview
This Bulk package protects the magnetic switch from damage. A safety precaution is taken by putting the magnetic switches into TO-243AA packages. A good performance can be achieved with magnetic switches that can deliver 8mA as the maximum current. It is possible for these switches to output 25mA as the maximum current when they are working. In order for the switches to function, they have 4 pins. There are 3 terminations in it. The switch normally supplies 12V to ensure reliable operation.
