CT II metal bezel integration
The following is a list of guidelines for integration with metal bezel. Please refer to the ClearTek II Integration Guide for complete integration instructions.
If your current design has a metal bezel, ensure that it does not directly contact the touch screen. The bezel should be appropriately grounded and very rigid. Use insulating tape or gasketing as a spacer.
Be aware that some plastic bezels have conductive paint that could act as a metal bezel so the same design rules apply in these instances.
If there is a conductive door or bezel, send a reset command to compensate for capacitance changes after closing the door. On most enclosures, a reset can be generated using the door open/close switch.
3M Touch Systems does not recommend metal touch screen mounting brackets. Make sure that any metal brackets are grounded.
Use closed cell foam; single sided adhesive per the ClearTek II Integration Guide. The seal may be compressed between the bezel and touch screen surface to create a good seal.
Note: Closed-cell foam has varying degrees of hardness, depending on its density. The advantages of the closed-cell foam compared to open-cell foam include its strength, and greater resistance to the leakage of air or water vapor.
