missing lacquer detector
A fully self-adjusting and self-calibrating lacquer detection sensor with no need for operator intervention. Both SC641 and SC651 sensors works with all white, coloured lacquers/ varnishes. The SC651 also works with clear varnishes.
- benefits

- A heartbeat signal for every sheet
- Make effective process improvements
- Promote better operator training
- Increase plant efficiency
extra costs from missing lacquer
If sheets or can stock get through the process in an uncoated or partially coated state, they can potentially cause serious problems: either can corrosion after filling or blunting of the tooling on a DRD press. This can lead to unplanned downtime, excess scrap, even customer complaint — all of which represent unnecessary costs.
risk reduction
It is now possible to reduce these risks by detecting uncoated sheets or can stock at line speed. The SC651 and SC641 sensors protect machinery and product against the problems caused by missing lacquer on blank sheets. It is designed to detect and signal that lacquer coatings are missing during the production process.
single or double sided
The SC641 or SC651 sensor can be fitted singly for sheet normally coated on one side, or with a second, opposing sensor for complete protection where sheets are coated on both sides.
Self-adjustment and self-calibration
The Missing Lacquer Detector is a fully self-adjusting and self-calibrating lacquer detection sensor with no need for operator intervention. The sensor automatically detects when a changeover occurs and learns the new lacquer characteristics.
peace of mind
Once fitted, this unique sensor provides peace of mind because uncoated sheets will be detected and a warning signal given. The output signal for missing lacquer can be linked to a user-defined response to isolate the sheet and protect the press.
Heartbeat signal
A heartbeat signal for every sheet assures operators that the sensor is working and coated sheets are passing through the press, guarding your equipment and your reputation. This signal may also be used as a sheet counter for process monitoring and SPC.
clear lacquers
Reliably detecting the presence of clear lacquer on can bodies is virtually impossible with the naked eye. Sensor manufacturers have also struggled to find a reliable solution to this challenge, but with the SC651 Sencon has achieved this technical breakthrough. For canmakers who do not need to detect clear lacquers on can bodies the SC641 sensor, which detects white, gold and coloured coatings but not clear lacquers, remains available.
