A3281LLTTR Overview
A magnetic switch is packaged in the Tape & Reel (TR) to prevent damage. To ensure safety, the magnetic switches are packaged in TO-243AA packages. A magnetic switch with good performance can deliver 8mA as its maximum current. Magnetic switches should have a maximum current of 25mA to operate. It contains 3 terminations. When this switch is functioning, its maximum voltage should be 24V. Normally, this switch will supply 12V voltage for reliable performance. The minimum voltage that can be supplied by this magnetic switch is 4.2V.
