Application of Optical Touch in Intercom of Intelligent Building

Published Time: 2022-10-25 15:49:20
Touch recognition is completed with the help of reflection of light through the light hole.

Intelligent building intercom (optical touch button)

 

Application

 

FMS-012L series optical touch chip is applied to the design of intercom products in intelligent buildings. It is mainly aimed at metal panels, and can also be used on glass and acrylic panels.

 

Working principle

 

With the help of the reflection, refraction and external light environment of the light transmission hole, comprehensive judgment is made to complete touch recognition.

 

Advantage

 

1. The metal panel is integrated, which is not easy to be damaged by external forces. The structure is solid and durable, and the appearance is novel and beautiful (the first in the industry);

 

2. The service life is 23 years, and the number of keystrokes is unlimited;

 

3. Waterproof, antifouling and moisture resistant;

 

4. Not affected by sunlight and incandescent light;

 

5. Multi media touch (hands, gloves, wood, metal);

 

6. Drive 1~16 keys to work;

 

7. Through dynamic 10V CS test, electrostatic contact discharge is ± 8KV, air discharge is ± 16KV, and electrical fast transient pulse group is ± 4KV.

Appearance

 

1. Spacing between keys ≥ 6.5 mm;

 

2. Character line width diameter ≥ 1.2mm;

 

3. Open the window at the characters of the metal panel. The window opening area can be filled with glue drops (epoxy resin A, B glue) or IMD to make it translucent;

 

4. The character area of glass and acrylic panel can be sprayed with white IR ink to make it translucent.
