A1140LLHLT Overview
Magnetic switches are packaged in Tape & Reel (TR) for protection against damage. In order to ensure the safety of the magnetic switches, they are packaged in SOT-23W packages. Switches require 3 pins to function. This document contains 3 terminations. If it works properly, this switch should produce a voltage of 24V. The switch will normally supply 12V for reliable operation.
