A3240ELHLT Overview
For protection against damage, the magnetic switch is packaged in the Tape & Reel (TR). The magnetic switches are put into SOT-23W packages for safety protection. The magnetic switches can supply 6mA as the maximum current for good performance. These switches can output 25mA as the maximum current when they work. The switches have 3 pins for working. There are 3 terminations in it. In general, the current output by the switches should be 25mA. The maximum voltage supplied by this switch should be 24V when it works. Normally, this switch will supply 12V voltage for reliable performance. The minimum voltage supplied by this magnetic switch can be 4.2V.
