July 23, 2009 - Pepperl+Fuchs Dura-Vue MLV12 Series Photoelectric Sensors are now available in diffuse mode with background evaluation. Dura-Vue background evaluation sensors provide a sensing range from 50 mm to 150 mm, with a 4 mm light spot that enables these sensors to detect even the smallest targets. They are engineered to detect all targets regardless of color or shape, making them well suited for use in material handling and packaging applications.Dura-Vue series sensors feature a harsh-duty IP67 rated metal-framed housing with swivel connector, and deliver reliable operation in temperatures as low as -40°F. Users will also benefit from highly visible front and rear LED status indicators, cross-talk protection and high immunity to ambient light.
With Pepperl+Fuchs patented 4-in-1 outputs, stocking and installation is significantly simplified because the sensor automatically sinks or sources its current based on the connected load. Alignment is easy with the aid of a visible red light source, while a potentiometer facilitates quick adjustments to the sensing range, as needed. Background evaluation photoelectric sensors work by establishing a light path to a reference background object and back to the sensor. Targets are detected when they pass in front of the sensor and disrupt the light path. Even rounded or curved targets that otherwise may reflect light away from the sensor, and targets with poor reflectivity, are reliability detected.
