Video: Light Sensor For Reliable Detection Of Transparent And Dark Objects
Originally developed for the detection of solar wafers, blue light diffuse sensors from Sensopart have proven to be reliable in numerous industrial applications. Especially in the detection of strongly light-absorbing objects, e.g. B. black plastic or carbon parts, or detection at an unfavorable, flat angle, blue light scanners show high process stability. The sensors also recognize transparent objects such as B. bottles, syringes or foils very reliably. In many cases, applications can be solved much more reliably using blue light technology.
Increased process stability
The higher process stability of the Blue Light series is due to the sophisticated Sensopart technology, which guarantees a coordinated concept of suitable transmit LEDs, optics and signal processing. The reliability of the sensors is further increased by the precise background suppression: Even very bright or reflective backgrounds, eg reflections from metal machine parts, do not interfere with the detection. With the compact sensor of the F 55 Blue-Light series, the background suppression can even be set using a potentiometer - according to Sensopart, this function makes it the only blue light sensor on the market.
The pioneer among blue light sensors was the F 10 Blue-Light subminiature retro-reflective sensor with a maximum scanning distance of 30 mm, which Sensopart has been offering since early 2014. New additions are now a further variant in subminiature format (max. Scanning range 50 mm) as well as versions in miniature format (series F 25 Blue-Light, max. Scanning range 80 mm) and in compact format (series F 55 Blue-Light, max. Scanning range 1200 mm)).
