A3251LLTTR Overview
A protective Tape & Reel (TR) package is used to protect the magnetic switch against damage. TO-243AA packages are used for safety reasons to protect magnetic switches. In order to be effective, magnetic switches can provide a maximum current of 7mA. If magnetic switches are to be output, the maximum current should be 20mA. It contains 3 terminations. If it works properly, this switch should produce a voltage of 24V. This switch should normally provide a voltage of 12V in order to ensure reliability. This magnetic switch can supply a voltage as low as 4.2V.
