A1121EUA-T Overview


A protective Bulk package is used to protect the magnetic switch against damage. For safety reasons, the magnetic switches are packaged in 3-SSIP packages. A good performance can be achieved with magnetic switches that can deliver 4mA as the maximum current. It is possible for these switches to output 25mA as the maximum current when they are working. Switches work with 3 pins. This has 3 terminations. In general, the switches should output 25mA of current.
