A1143LLHLT 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 17mA as its maximum current. It is necessary to have a 3 pin for the switches to work. A total of 3 terminations have been reached. When this switch is functioning, its maximum voltage should be 24V. In normal conditions, this switch will deliver 12V voltage.
