Precautions:
a. When installing, make sure to touch the surface of the isolation media and closely integrated, fixed! Can not leave the air gap in the middle! Installed after the power, wait three seconds after initialization, normal operation can!
b. Recommended installation method: (when the general production is: Shell card slot + hot melt adhesive)
First, housing design a card slot, touch keys can firmly stuck into them.
Second, the use of adhesives, the touch buttons and shell close, you can live with hot glue.
Third, the use of double-sided tape, stick directly to the touch buttons inside the enclosure.
c. This product is a high sensitivity, the air, the distance of about 6mm where you can sense the touch surface, if the use of isolation media, be sure to make the distance from the left hand test (greater than 10mm best)
d. Select the shell material: It is recommended to use a dielectric constant between 1.5 and 4 of the material, the shell material can be in direct contact with the induction PAD, avoid the use of metal and carbon-containing conductive material, it is recommended to use a dielectric constant of 1.5 to 4 K in between material, such as glass, acrylic, plastic and so on.
