HCCD + EPC-A12
Sensing a printed line within the roller path
An HCCD camera sensor is mounted beside a longitudinal printed line. The same machine also shows an EPC-A12 controller with CCD text on its display.

Choose Your Sensing Reference
Start with the material and the feature you need to follow
Material transparency and the choice of an edge or printed-line reference help narrow the sensor selection.
Transparent film · Edge reference
Ultrasonic sensing
Consider US-500S for transparent films or low optical contrast. Confirm the material sample, sensing gap and mounting space.
Explore US-500SOpaque material · Edge reference
Photoelectric sensing
Consider PS-400S for standard opaque web materials. Review edge contrast, surface reflections and the sensor position with your material sample.
Explore PS-400SPrinted line · Visual reference
Camera and line sensing
Explore HCCD when the reference is a printed line. Confirm line contrast, working distance and the controller interface for your application.
