A3281LLTTR-T Overview
Magnetic switches are packaged in Tape & Reel (TR) for protection against damage. For safety reasons, the magnetic switches are packaged in TO-243AA packages. A magnetic switch with good performance can deliver 8mA as its maximum current. Magnet switches must be able to output 25mA current. 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. Magnetic switches can provide voltages as low as 4.2V.
