A3251EUA Overview
The magnetic switch is packaged in the Bulk to ensure it is protected against damage. As a safety precaution, the magnetic switches are packaged in 3-SSIP packages. A magnetic switch is capable of supplying 7mA as the maximum current for maximum performance. To be output, magnetic switches need a maximum current of 20mA. The file contains 3 terminations. The maximum voltage supplied by this switch should be 24V when it works. The switch will normally supply 12V for reliable operation. It is possible for this magnetic switch to provide a voltage of 4.2V at its minimum.
