Overview
- Digital read-out of gray-scale values via the RS-232 Interface
- High geometric resolution and very high contrast resolution
- Teach-In, dynamic Teach-In, external Teach-In, RS-232 Interface
- 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 printed markings and the background.
Features WP02/WP04
WP02 and WP04 series sensors are distinguished by high geometric and contrast resolution. These sensors can be adjusted for use with any application thanks to an extremely small spot, high switching frequency and a white light diode with longer service life. Various Teach-In modes are available in this case as well. Additionally, the switching threshold can be readjusted with the help of a key potentiometer. All sensor settings can also be selected via the integrated RS-232 interface, and values generated by the sensor can be read out via the same interface.
Interface
Sensor functions can be activated and scanning results can be acquired via the RS-232 interface.
Adjustments
Adjustments are made with the Teach-In keys, externally or via the RS-232 interface.
