A3251ELT Overview

During packaging, the magnetic switch is protected against damage with the Bulk. TO-243AA packages are used for safety reasons to protect magnetic switches. For good performance, the magnetic switches can supply 7mA. To be output, magnetic switches should be rated at a maximum current of 20mA. The file contains 3 terminations. If it works properly, this switch should produce a voltage of 24V. In order to provide reliable performance, this switch normally supplies voltage 12V. A magnetic switch can supply a voltage as low as 4.2V.
