A3281EUA Overview
This Bulk package protects the magnetic switch from damage. 3-SSIP packages are used for safety reasons to protect magnetic switches. For good performance, the magnetic switches can supply 8mA. It is recommended that magnetic switches have a maximum output current of 25mA. In total, 3 terminations have been recorded. Normally, this switch should supply a maximum voltage of 24V. In order to provide reliable performance, this switch normally supplies voltage 12V. This magnetic switch can provide 4.2V voltage as the minimum voltage.
