W 160 Photoelectric switches Photoelectric W 160: Miniature series for proximity switches, BGB Photoelectric optimum solutions proximity switches, energetic Photoelectric reflex switches optic cables with approx. 50 different configuration options are available as accessories. W 160 switches have proven particularly successful in the following sectors: electronic component and printed circuit board production, the packaging and printing industries, assembly and handling systems, the construction of special- purpose machines, and conveyor systems.
