                                                A3213ELHLX-T Overview
This Tape & Reel (TR) package protects the magnetic switch from damage. In order to prevent damage to the magnetic switches, they are packaged in SOT-23W packages. The magnetic switches are capable of supplying 2mA as their maximum current. In its maximum state, these switches can output 1mA. In total, 3 terminations have been recorded. If this switch is functioning properly, it should supply a voltage of 5.5V. In most cases, this switch will supply 3V voltage to ensure relability. Magnetic switches can provide voltages as low as 2.4V.
