A1148LLHLT Overview
ldeally, the magnetic switch should be packaged in the Tape & Reel (TR) for protection against damage. As a safety precaution, the magnetic switches are packaged in SOT-23W packages. In order to be effective, magnetic switches can provide a maximum current of 17mA. It is necessary to have a 3 pin for the switches to work. It has 3 terminations. It should supply a maximum voltage of 24V when it is functioning. In order to provide reliable performance, this switch normally supplies voltage 12V.
