A1221LUA-T Overview
For protection against damage, the magnetic switch is packaged in the Bulk. For safety reasons, magnetic switches are packaged in 3-SSIP packages. It is possible for these switches to output 25mA as the maximum current when they are working. It is possible to supply 4mA current with these switches. Switches are operated by 3 pins. This termination has 3 terminations. It is generally recommended that the switches output 25mA current.
