Print Mark Sensor- WM03NCT2
Documentation
- User Manual (PDF 914kb)
- Data Sheet (PDF 485kb)
Overview
- Compact Housing
- Small Light Spot
- Teach-In, external Teach-In, RS-232 Interface
- White Light for recognition of any print mark combinations
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 WM03
WM03 series sensors are capable of differentiating extremely fine grey tone variations within a scale of black to white. They are equipped with various Teach-In modes (e. g. dynamic Teach-In, two point Teach-In and window Teach-In), which allow for optimized sensor adjustment for any application. Beyond this, the sensors are equipped with a delay function for time delayed deactivation of the output.
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.
