A1145ELHLT Overview
For protection against damage, the magnetic switch is packaged in the Tape & Reel (TR). SOT-23W packages are used for safety reasons to protect magnetic switches. As a maximum current, magnetic switches can supply 17mA. The switches have 3 pins for working. It contains 3 terminations. Normally, this switch should supply a maximum voltage of 24V. For reliable performance, this switch usually provides 12V voltage.
