E.g:

HTDS-SCR: single-key,conventional,red backlit touch module

In touch media,such as portable media players and mobile handheld devices,such as large-capacity,high-visibility products,has been widely adopted. Because of its ease of use,fashion and low cost advantages,more and more electronic products from the traditional mechanical keys to touch the touch button.

HTTMSeries touch key module has the following characteristics:

1.There is no mechanical parts,will not wear,unlimited life,reduce the cost of late maintenance;

2.The sensing part can be placed behind any insulating layer (usually glass or plastic material),it is easy to make the keyboard with the surrounding environment sealed to play the role of moisture and water;

3.Panel design arbitrary,button size,shape any design,characters,trademarks,perspective and other combinations,so that the overall sense of the product stronger;

4.Compared with the physical buttons,touch the button is more vulnerable;

5.The output of the adjustment signal can be output by latching the output or level by modifying the resistance on the back (see section 3.3.2);

6+ 2.7V ~ +6 V wide voltage input range,+3.3 V signal output,can be directly used to drive the relay,optocoupler,LED lights and other original;

7.-30 ~ +70 ° Operating temperature range;

8.Touch sensitive,no hysteresis,delay,flicker and other adverse reactions;

9.Built-in anti-jamming algorithm,with excellent anti-jamming performance.
