A3251LUA Overview

A protective Bulk package surrounds the magnetic switch to protect it from damage. For safety reasons, magnetic switches are packaged in 3-SSIP packages. In order to be effective, magnetic switches can provide a maximum current of 7mA. If these switches work, they can output 20mA as the maximum current. 3 pins are used to operate the switches. A total of 3 terminations have been reached. In general, the current output by the switches should be 20mA. Switches like this should supply voltages no higher than 24V. This switch will normally supply 12V voltage for reliable operation. This magnetic switch can provide 4.5V voltage as the minimum voltage.
