1 W 0 Photoelectric switches Photoelectric proximity switches, BGB Photoelectric proximity switches, energetic W 0: iniature series for optimum solutions Photoelectric reflex switches Through-beam photoelectric switches P/e switches w. fibre-optic cable (proximity mode) P/e switches w. fibre-optic cable (through-beam mode) SENSICK CATALOGUE PPrincipal system characteristics are simple handling, large scanning ranges and a reduced number of sensor types thanks to integrated L./D. switches. Integrated intelligence features such as pre-failure signalling output, test input (cable versions only) or external teach-in (WLL 0 T) increase system reliability under severe environmental conditions. All W 0 optic variants are available in housing versions with axial or 90 light emission. WLL 0 fibre-optic cable photoelectric switches with switching point adjustment (manual using potentiometers or automatic at the push of a button using the teach-in method) complete the W 0 series. LL plastic fibreoptic cables with approx. 0 different configuration options are available as accessories. W 0 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 specialpurpose machines, and conveyor systems. The scanning ranges: WS/WE 0 through-beam photoelectric switch: m, slotted mask as accessory, WL 0 photoelectric reflex switch: m (PL 80 A), with polarising filter, WT 0 photoelectric proximity switch: energetic: scanning distance up to 00 mm (90 % remission), for standard scanning tasks; with focused optics: scanning distance between 8 and 0 mm, background blanking, small light spot, high sensitivity; with divergent optics (angle of dispersion approx. 0 ): scanning distance up to 80 mm; ideal for transparent objects.

2 W 0 m Resistor production: fibre-optic WLL 0 switches can detect even the thinnest of wires without any problem. b Checking the presence of caps and covers: Using a WT 0 photoelectric proximity switch to detect lids and WS/WE 0 through-beam photoelectric switches to monitor system timing. v The WT 0 miniature photoelectric proximity switch is used in film and foil processing to control feed tension. n Checking caps and labels using WT 0 photoelectric proximity switches.
