A1211ELHLT-T Overview
Magnetic switches are packaged in Tape & Reel (TR) for protection against damage. Safety precautions are taken by packaging the magnetic switches in SOT-23W packages. A magnetic switch with good performance can deliver 7.5mA as its maximum current. When these switches are working, their maximum current will be 25mA. For the switches to work, they have 3 pins. This document has 3 terminations. A switch's current output should generally be 20mA.
