Working voltage: 2.7 ～ 6V
Working temperature: 30 ～ + 70 ℃
The output voltage of out pin is + 3.3V ± 0.1V
Output current of out pin: 500mA
HTTM series touch key module has the following features:
1. No mechanical parts, no wear and tear, unlimited life, reduce the cost of later maintenance;
2. The sensing part of the keyboard can be placed behind any insulating layer (usually glass or plastic material), so it is easy to make the keyboard sealed with the surrounding environment, so as to play the role of moisture-proof and waterproof;
3. The panel pattern is arbitrary, the key size and shape are designed arbitrarily, and the characters, trademarks and perspective windows are matched arbitrarily to make the overall feeling of the product stronger;
4. Compared with physical buttons, touch buttons are not easy to be damaged;
5. The output of signal can be adjusted to latch output or level hold output by modifying the resistance on the back (see 3.3.2 for details);
6. + 2.7V - + 6V wide voltage input range, + 3.3V signal output, can be directly used to drive relays, optocouplers, LED lights and other components;
7. Working temperature range from - 30 ℃ to + 70 ℃;
8. Sensitive touch, no delay, flicker and other adverse reactions;
9. Built in anti-jamming algorithm, with good anti-jamming performance.
