I. Silicone keyboard composition
1.silicone button
2.PCB keyboard decoding board
3.USB / PS2 / RS232 (serial port) output cable
4. It has the characteristics of high and low temperature resistance, moisture and moisture resistance, abrasion resistance and strong feel. Strong waterproof performance, temperature range up to -50 ~ 250 ℃.

Silicone key reference data:
1. Load pressure: 20 ~ 500g
2. Contact resistance: <150Ω
3. Press times: 0.5 ~ 30 million times
4. Working temperature: -20 ~ 180 ℃
5. Storage temperature: -30 ~ 250 ℃.
6. Contact rate: 5 microamps at 12 volts DC for 0.5 seconds and 20 million cycles.
7, contact elasticity: less than 1.2 million times.
8, insulation resistance: greater than 10 to the 12th power, ohms at 500 volts DC.
9. Insulation capacity: 25 to 30 kV / mm
Key press pressure reference data:
1. The pressing pressure is about 50-80g, which is generally suitable for silicone keys of computer keyboards and calculator keys. The pressing force in this range is not high, is relatively low, it is easy to press, and it is suitable for silicone buttons that need to be clicked frequently.
2. The pressing pressure is about 80-120g, which is generally suitable for electrical buttons and remote control buttons. The pressing pressure is suitable, the feel is comfortable, and the resilience is also good.
3. The pressing force is 120-180g, which is generally suitable for affecting equipment, industrial instruments, and mechanical remote control. The pressing force is much larger than the second type. Generally, it is suitable for larger silicone keys. The resilience is also superior, but not Suitable for products with frequent clicks.
4. The pressing pressure is more than 180g. Generally, such silicone pressure keys are relatively rare. It is suitable for special industries, such as medical, aviation and other industries. Frequent short-term use of fingers is more acidic.
1. The output interface series is: USB / PS2 / RS232 (serial port)
2. Operating system: All Windows, Linux, Unix, Mac OSX, Vxworks, Android
Application areas:
Laboratory, various medical places, hospitals, clinics, dentistry, such as carts, diagnostic equipment, operating rooms, dialysis centers, etc .;
Industrial areas: industrial automation, pharmaceuticals, oil and gas, food and beverages; dirty or dimly lit work environments.
Other industries.
