A1211LLHLT-T Overview
The magnetic switch is packaged in the Tape & Reel (TR) to ensure it is protected against damage. A safety precaution is taken by putting the magnetic switches into SOT-23W packages. A good performance can be achieved with magnetic switches that can deliver 7.5mA as the maximum current. Switches of this type are capable of delivering 25mA as the maximum current when they are in use. If magnetic switches are to be output, the maximum current should be 25mA. Switches are operated by 3 pins. Switches should generally output 25mA current. For the magnetic switches, 150°C is the maximum operating temperature. This magnetic switch, however, cannot operate at temperatures below -40°C. This electronic component could supply 24V as the maximum voltage. Minimum voltage for these switches is 3.8V.
