The sensor's proper functionality will be compromised if it is exposed to strong reflections! |
An external reflective surface is a surface located surface located outside the active the active area, but close enough to be to be reached by the IR light emitted by the sensor module. Depending on the angle and the reflectance of the surface, reflected light can enter the sensor module and interfere with touch object detection. If the external reflective surface is close to the touch active area, it is recommended to make sure it has a low reflectance in the direction back towards the sensor module.
