A1227LLTTR-T Overview
For protection against damage, the magnetic switch is packaged in the Tape & Reel (TR). The magnetic switches are put into TO-243AA packages for safety protection. These switches can output 25mA as the maximum current when they work. The maximum current supplied by these switches can be 6mA. The switches have 4 pins for working. There are 3 terminations in it. In general, the current output by the switches should be 25mA. Normally, this switch will supply 12V voltage for reliable performance. The minimum voltage supplied by this magnetic switch can be 3.8V.
