Siemens 6AV6642-0BA01-1AX0 Human Machine Interface Touch Panel

The Siemens 6AV6642-0BA01-1AX0 SIMATIC TP177B is a 5.7-inch color touch panel HMI designed for industrial automation. It uses a resistive analog touchscreen and a 320×240 pixel STN display with 256 colors for clear operator feedback. An ARM processor runs at 200 MHz with Flash/RAM, and 2,048 KB are available for user data. Interfaces include MPI/PROFIBUS DP, RS-485, RS-422, USB, and Ethernet 10/100, plus a printer interface and an MMC card slot; an RS-232 port is optional. Configuration is via WinCC Flexible 2005, making it suitable for classic Siemens control architectures. The TP177B PN/DP family designation indicates compatibility with Siemens’ SIMATIC HMI ecosystem, while the device supports vertical mounting and a maximum tilt of 35° without external ventilation. The backlight MTBF is 50,000 hours at 25 °C, supporting reliable operation in demanding environments.
