A3281EUA-T Overview


The magnetic switch is packaged in the Bulk in order to prevent damage. The magnetic switches are put into 3-SSIP packages for safety protection. A good performance can be achieved with magnetic switches that can deliver 8mA as the maximum current. The maximum current these switches can supply when they work is 25mA. Switches are operated by 3 pins. This document has 3 terminations. In general, the switches should output 25mA of current. If this switch is functioning properly, it should supply a voltage of 24V. Normally, this switch will provide 12V voltage in order to provide reliable operation. It is possible for this magnetic switch to supply a voltage as low as 4.2V.
