A1227LLTTK-T Overview
In order to protect the magnetic switch from damage, it is packaged in the Tape & Reel (TR) enclosure. In order to prevent damage to the magnetic switches, they are packaged in TO-243AA packages. A good performance can be achieved with magnetic switches that can deliver 6mA as the maximum current. This has 3 terminations. A switch's current output should generally be 25mA. When this switch is working, it should supply a voltage of 24V . In order to provide reliable performance, this switch normally supplies voltage 12V. With this magnetic switch, a voltage of 3.8V is the minimum voltage available.
