Print Mark Sensor

WP04NAT80

Digital read-out of gray-scale values via the RS-232 Interface
Teach-In, dynamic Teach-In, external Teach-In, RS-232 Interface
Very high contrast resolution
Very small spot: 1,4 × 4 mm

These sensors have been specially designed to recognize print marks. They have a very small spot and use a white light LED with long service life. Only one sensor is required for the recognition of all color combinations, as well as the difference in brightness between print marks and the background.
