Balluff LD20-01-MM18-NAP-12-30VDC LD2001 is a diffuse-reflective photoelectric sensor in an M18 (Ø18 mm) housing designed for compact sensing tasks on automated lines. It operates from 10–30 V DC and uses a 4-pin M12 connector for wiring, with sensing ranges from 1 to 250 mm in diffuse mode. The housing is brass, nickel-plated, with a glass sensing surface and IP67 protection, suited for harsh industrial environments; output is PNP normally open (NO) or normally closed (NC) depending on the variant. Common applications include part presence detection, gap sensing, and orientation checks on conveyors, pick-and-place, and packaging lines.
