A3251EUA-T Overview
Designed to protect magnetic switches from damage, the Bulk package contains the switches. 3-SSIP packages are used for safety reasons to protect magnetic switches. In order to be effective, magnetic switches can provide a maximum current of 7mA. In operation, these switches can output a maximum current of 20mA. It is necessary to have a 3 pin for the switches to work. This has 3 terminations. In general, the current output by the switches should be 20mA. In order for this switch to work, the maximum voltage should be 24V. In most cases, this switch will supply 12V voltage to ensure relability. A magnetic switch can operate at a minimum voltage of 4.2V.
