Colour Sensor Archive
The colour sensor works with a a fibre optic cable projecting modulated bright white light from an LED onto the tarket. This product is well suited to checking the "tax strip" on a cigarette box. Some of the light that is reflected from the target back into the fibre optic cable onto a perceptive True-
This print mark detection sensor can work at high speed up to 20kHz, and can look at spots just 1.5mm in diameter. The sensing distance can be up to 20mm. This print mark detection sensor is ideal for labels, foils, packaging, printing and paper applications.
This colour sensing solution comes in 3 parts – you have a light source and a receiver in M18 bodies, and then the separate electronics in a rugged industrial housing. Sensing distances can be up to 200mm, the response time is typically just 100uS.
With over 1,000 of these colour sensors in the field they have proven to be very popular and reliable over the years. You can store between 1 and 4 colours with the ‘teach in’ function, the response time can be as little as 400us and the sensing range up to 80mm. The halogen light source allows for a massive colour spectrum and provides high performance, the object size can be as little as 1mm and the unit comes ina robust industrial package.
There are two type of this colour sensor, one which can store one colour, the other can store 4. The colours are quickly and easily stored using the ‘teach in’ function and the LED illumination ensures a maximum operational life. The sensing distance can be from 1 to 50mm, the object size can be as small as 0.5mm and the response time is 1 millisecond.
This 12 channel colour sensor has a 0.5 millisecond response time and an RS232 interface. They are easily programmed using the ‘teach in’ function and can recognize 4 colours. The integral LED illumination has a long life and there is a great deal of flexibility with the fibre optics available.
