As compact as a photoelectric switch, the device offers a scanning distance of 2 m and highly precise background suppression – regardless of the object’s colour.

EN 62061, however, also applies now – when the safe design of electrical controllers is concerned. What does the standards duo mean in practice? And why are there two standards for the “same” subject? Which standard should machines constructors and plant users employ? Dr. Michael Schaefer and Michael Hauke from the Trade Association of Industrial Safety (BGIA) provide SICK insight with a full explanation.
