A3251LLTTR-T Overview
Magnetic switches are packaged in Tape & Reel (TR) to prevent damage. For safety reasons, the magnetic switches are packaged in TO-243AA packages. A magnetic switch with good performance can deliver 7mA as its maximum current. It is possible for these switches to operate at a maximum current of 20mA. Magnet switches should have a maximum current of 20mA in order to function correctly. It is necessary to have a 4 pin for the switches to work. A maximum operating temperature of 150°C can be set for the magnetic switches. A magnetic switch must operate at a temperature above -40°C to work.
