INTEGRATING THE SENSOR
To integrate the sensor, you will require a suitably sized LCD with a display area matching the
active area of the sensor, as shown in Figure 1 (the active area of the sensor can be found on the
corresponding Zytronic sensor drawing).
SUITABLE LCD TO MOUNT THE SENSOR TO
Foam gasket should be used around the perimeter of the LCD to provide an air gap between the LCD
face and the rear of the sensor, as shown in Figure 2. This air gap is necessary to prevent excessive
electrical noise from the LCD causing interference to the sensor. Guidelines for the required thickness
of the gasket can be seen in the table below and are sufficient for most LCDs. Some LCDs with very
high levels of noise may require greater spacing which would need to be determined by testing.
