A3251LLTTR Overview
Magnetic switches are packaged in Tape & Reel (TR) to prevent damage. For safety reasons, magnetic switches are packaged in TO-243AA packages. For good performance, magnetic switches can supply 7mA as their maximum current. For magnetic switches, the maximum current should be 20mA. It has 3 terminations. When this switch is working, it should supply a voltage of 24V . For reliable operation, this switch supplies 12V voltage. Magnetic switches can supply voltages as low as 4.2V.
