A3251ELTTR Overview

An integrated magnetic switch is packaged within the Tape & Reel (TR) in order to protect it against damage. Safety precautions are taken by packaging the magnetic switches in TO-243AA packages. A magnetic switch can supply a maximum current of 7mA if it is well designed. For magnetic switches to be actuated, the maximum current should be 20mA. As far as terminations are concerned, there are 3. In order for this switch to function properly, it should supply a voltage of 24V. In normal circumstances, this switch will provide 12V voltage to ensure reliable operation. In this magnetic switch, 4.2V is the minimum voltage that can be supplied.
