A3240LLHLT Overview
ldeally, the magnetic switch should be packaged in the Tape & Reel (TR) for protection against damage. The magnetic switches are put into SOT-23W packages for safety protection. A good performance can be achieved with magnetic switches that can deliver 6mA as the maximum current. These switches can output 25mA as the maximum current when they work. Switches have 3 pins for operation. This has 3 terminations. There should be 25mA current output from the switches in general. In order for this switch to function properly, it should supply a voltage of 24V. In normal conditions, this switch will deliver 12V voltage. Magnetic switches are capable of providing voltages as low as 4.2V.
