Out with the old, in with the new: The contrast sensors from the F 25 series are assembly and connection compatible with the conventional standard housing (image on the bottom). The fastening bores are aligned in the same distance from each other. The integrated cable with a M12-connector fits to the corresponding mating connector.
All variants have their specific benefits: while the white-light and RGB scanners can detect even the smallest of contrast differences, the red-light laser offers the advantage of a particularly small light spot (Ø 0.7 mm in focus) in combination with a long scanning distance. The F 25 series is further characterised by a particularly high depth of field so that the sensors work very reliably even with vibrations or fluttering materials, e.g. during the detection of paper webs in the print industry.
During RGB multi-colour evaluation by the FT 25-RGB, the sensor automatically selects the ideal transmission colour (red, green or blue) for absolutely reliable detection of contrasts. The FT 25-W/RGB variant offers particularly high positioning accuracy and reliable detection – even at high process speeds – thanks to its minimal response time of ≤ 20 µs.
Moreover, all product variants offer the legendary SensoPart user-friendliness: the sensors can even be configured during running operation via teach-in, whereby the switching threshold is automatically adapted to object and mark colours and the background. After teach-in, the quality of the taught-in contrast is communicated via the light spot. Users thus receive unambiguous feedback on how reliable their process is.
Rod mounting allows user-friendly and precise sensor alignment.
