Transcription

1 CS Colour sensors Colour sensors CS Colour sensors: When it s the colour that counts A brief description of the process: an object is illuminated using light of varying spectral composition. The light reflected is received by the sensor, digitised, and then evaluated and stored by a microprocessor. These measured values are compared with previously stored reference values. If the values are within the tolerance range, a switching output IIdentification, sorting, checking and evaluation automation involves many tasks where colour is an important factor. CS colour sensors are able to detect colour as a control and quality criterion quickly and precisely both with incident light and with transmitted light, with transparent and nontransparent materials. used to control the machine is set. Two colour sensor variants are available: up to colours can be saved in memory, scanning distances of. and 0 mm, simple operation using a teachin function, die-cast housing, enclosure rating IP, rotatable M plug, PNP and NPN switching outputs.

The colours can be selected individually by changing the position on the rotary switch. Reference colours can be stored by simply pressing a button. The programming procedure can also be carried out automatically via the external teach-in (ET) input cable. With each pulse, the sensor moves into programming mode, establishes the colour of the object being scanned and is then ready to be used again. After external teach-in the device is ready for use after 00 ms.
