Reflex Sensors for Contrast Detection

Reflex Sensors for Contrast Detection measure the brightness of objects. The switching threshold is set to a specified degree of brightness. The brightness of the scanned surface is compared with the specified brightness value by integrated analysis electronics. Bright objects reflect more light than dark objects, and can thus be recognized from greater distances.

Applications

• Recognition of contrast markings
• Recognition of markings on encoding discs
• High speed recognition of extremely small parts and markings
• Wire recognition Rapid edge detection
• Rapid counting of plug connectors
