A1101EUA-T Overview
A protective Bulk package is used to protect the magnetic switch against damage. A safety precaution is taken by putting the magnetic switches into 3-SSIP packages. A magnetic switch can supply a maximum current of 7.5mA if it is well designed. It is possible for these switches to output 25mA as the maximum current when they are working. There is 7.5mA maximum current that these switches can supply. For the switches to work, they have 3 pins. This document contains 3 terminations. Switches should generally output a current of 20mA. Normally, this switch should supply a maximum voltage of 24V. It is expected that this switch will supply 12V voltage to ensure reliable operation.
