The LAD402P is mechanically driven by the contactor’s armature. When the contactor coil energizes, the armature moves upward (in a standard vertical mount) or downward (in a horizontal mount). This motion pushes a plunger into the bottom of the LAD402P, switching its internal contacts. Constant-current sink outputs that connect to the cathode

If you have any more details about the component (like its supposed function, manufacturer, or where you encountered it), I might be able to provide more targeted advice. This motion pushes a plunger into the bottom
