A1421LK-T Overview


Bulk package done to protect the magnetic switch from damage. In order to prevent damage to the magnetic switches, they are packaged in 4-SSIP packages. If these switches work, they can output 25mA as the maximum current. Switches of this type can deliver currents up to 7mA. Switches require 4 pins to work. 4 terminations are contained in it. The switches should normally output 25mA current. In a working switch, the maximum voltage should be 26.5V. It is expected that this switch will supply 12V voltage to ensure reliable operation. There is 4V minimum voltage that this magnetic switch can provide. Magnetic switches can provide 12V voltage when operating.
