19’’ with 4:3 capacitive touch panel for Numerical Control System

19’’ with 4:3 capacitive touch panel :

Project Background

In Numerical Control Systems (CNC) and other industrial control applications, touch interfaces must meet extremely demanding requirements, including:

• Stable operation under extreme temperature conditions

• Resistance to continuous vibration, mechanical shock, and electromagnetic interference

• Reliable performance in environments exposed to oil, dust, moisture, and chemical substances

• Accurate operation while operators wear thick protective gloves

To address these challenges, we provided a customized 19'' 4:3 capacitive touch panel solution, which has been successfully deployed in CNC systems.
