MOLOSswitch coupling systems of MOLLET are equipped with inductive limit switches selectable with or without NAMUR-standards in order to signal the coupling situation during the filling process at silos and tanks or at coupling stations. The coupling with internal thread has a built-in limit switch with metal housing. During the coupling of the counter coupling or hose coupling the limit switch will be actuated. Blank caps do not activate the limit switch.
