A3281LLHLT-T Overview
Magnetic switches are packaged in Tape & Reel (TR) for protection against damage. For safety reasons, the magnetic switches are packaged in SOT-23W packages. A magnetic switch with good performance can deliver 8mA as its maximum current. When these switches are working, their maximum current will be 25mA. It is necessary to have a 3 pin for the switches to work. A total of 3 terminations have been reached. As a general rule, switches should output a current of 25mA. When this switch is functioning, its maximum voltage should be 24V. In normal conditions, this switch will deliver 12V voltage. Magnetic switches can provide voltages as low as 4.2V.
