A3425LK-T Overview
The magnetic switch is packaged in the Bulk to ensure it is protected against damage. 4-SSIP packages are used for safety reasons to protect magnetic switches. Good performance is achieved by magnetic switches that can supply 6mA as maximum current. When these switches are working, 20mA is the maximum current they can output. For the switches to function, there are 4 pins. It contains 4 terminations. In general, the switches should output 70mA of current. The maximum voltage supplied by this switch should be 18V when it works. The switch is usually set to supply 12V voltage to ensure reliable operation. A magnetic switch can operate at a minimum voltage of 3.3V.
