A1221EUA-T Overview

A magnetic switch is packaged in the Bulk to prevent damage. It is necessary to put the magnetic switches into 3-SSIP packages in order to ensure their safety. In their operating mode, these switches can output a maximum current of 25mA. There is a limit to 4mA current that can be supplied by these switches. Switches are operated by 3 pins. The document has 3 terminations. Switches should generally output 25mA current. A nominally working device can supply a constant current of 4mA.
