A3281ELHLT-T Overview


This Tape & Reel (TR) package protects the magnetic switch from damage. A safety precaution is taken by putting the magnetic switches into SOT-23W 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 3 pins. There are 3 terminations in it. There should be 25mA current output from the switches in general. When working, this switch should supply 24V voltage at its maximum. The switch normally supplies 12V to ensure reliable operation. In this case, the minimum voltage supplied by the magnetic switch can be 4.2V.
