Description
A3281ELT-T Overview
Magnetic switches are packaged in Bulk for protection against damage. For safety reasons, the magnetic switches are packaged in TO-243AA packages. A magnetic switch with good performance can deliver 8mA as its maximum current. When these switches are working, their maximum current will be 25mA. It is necessary to have a 4 pin for the switches to work. A total of 3 terminations have been reached. As a general rule, switches should output a current of 25mA. In normal conditions, this switch will deliver 12V voltage.
