The Square D Switches & Sensors Telemecanique XS612B3DBM12 is an inductive proximity sensor in the M12 cylindrical format, a non-contact presence detector used on conveyors, machine tools and packaging lines to sense metal targets without mechanical wear on the sensing element. UPC 389119045547 is printed on the carton for receiving inspection; missing it on a delivery is a flag to check the packing slip before put-away.
Class function in the panel
Inductive proximity sensors in this format replace mechanical limit switches on rotating or high-cycle equipment, run on a two- or three-wire DC interface, and switch their output when a ferrous or non-ferrous target enters the rated sensing window — no mechanical contact, no cam to wear.
