More options for colour sensor
The BFS 26K colour sensor that works as a true three-channel colour recognition system without needing an external light source is now available in two new versions.
Balluff's successful BFS 26K colour sensor that works as a true three-channel colour recognition system without needing an external light source is now available in two new versions: with a small square 2mm light spot ideal for small component detection such as on circuit boards, and a narrow rectangular 1 x 5mm light spot designed for detecting extended or unusually shaped colour markings such as on cables The BFS 26K uses an integrated, pulsed white light source, eliminating the need for external illumination and making it insensitive to ambient light

The sensors never let themselves be confused by the ambient lighting like the human eye.
No colour remains undetected by the sensor.
One of the smallest colour sensors on the market with its dimensions of just 50 x 50 x 17mm and with a 270-degree rotatable connector, the BFS 26K is fully integrated, needing no separate amplifier and can therefore fit into the smallest spaces.
It and can be programmed using the two teach-in buttons or through the control line when located in inaccessible locations or when remote or automatic set up is needed.
Each of the three digital outputs can be calibrated using five tolerance levels.
The sensor can also work in three different modes: normal diffuse scanning; a retroreflective mode, ideal for detection of coloured bottles; and a colour scan mode where the user can show the sensor an array of colours to learn and then later recognise.
This mode is ideal for reliably detecting packaging and printing containing a wide variety of colours.
