A3281LUA Overview
Bulk package done to protect the magnetic switch from damage. Safety precautions are taken by packaging the magnetic switches in 3-SSIP packages. A magnetic switch can supply a maximum current of 8mA if it is well designed. In operation, these switches can output a maximum current of 25mA. Switches require 3 pins to work. It contains 3 terminations. As a general rule, the switches should output 25mA. It should supply a maximum voltage of 24V when it is functioning. This switch will normally supply 12V voltage for reliable operation. In this magnetic switch, 4.2V is the minimum voltage that can be supplied.
