Color sensors
By Staff -- Test & Measurement World, 8/1/2007
Pepperl+Fuchs has introduced the Dura-Vue DF12 color sensor that can be taught to recognize three independent colors. The company says that programming is easy via a potentiometer setting at the sensor or by a remote teach signal from a PLC. Each of the three channels can be taught to detect minute color variations with varying degrees of tolerance. Pepperl+Fuchs, www.am.pepperl-fuchs.com.
