You choose: Suitable WLL 0(T) versions, optimised for various typical uses, are available WLL 0T with teach-in: This teach-in version simplifies handling: the switching threshold and switching hysteresis are automatically set, via a push button (Teach-in). Sender LED red or green light: Selects the most suitable emitted light for optimum detection of colour contrasts. WLL 0- with manual switching threshold adjustment: The cost-effective solution for all standard applications. WLL 0 High Speed: 0,000 switching operations per second - the optimum for high speed applications. WLL 0A with analogue output: For easy measurement and control. Large selection of suitable fibreoptic cables: Fibre-optic cable range LL. For WLL 0, there are around 0 LL versions, offering maximum flexibility and choice for your requirements. Typical uses for these WLL 0 / LL fibre-optic cable combinations: semiconductor industry, electronics assembly, packaging technology, handling and assembly systems, special-purpose machinery, construction and precision engineering.

Teach-in mode selector switch Separate from other operating mode selector switches, therefore simple to operate, no double functions. SET : WLL 0T in manual Teach-in mode. Optimum switching point setting by simply pressing a botton (once or twice). RUN : The taught-in switching threshold and switching hysteresis are saved in the EEPRO. Accidental change of the taught-in parameter is not possible. After seconds the WLL 0T operates in the sensor mode. The saved Teach-in values are retained for an unlimited period of time even if the voltage is interrupted for a longer time. delay t off For switching output. Also switchable, 0 ms fixed.
