Features:
- A 7.5-inch TFT touchscreen and membrane keys combine displayed information with local operator input.
- An emergency-stop button and two three-stage enabling buttons are integrated into the handheld housing.
- The 0AA1 order code identifies the HT 8 configuration without a handwheel.
Siemens 6FC5403-0AA20-0AA1 brings mobile SINUMERIK operation and machine-control functions into one IP65 handheld terminal.
Its safety-related controls remain physically separate from the touchscreen while staying accessible to either hand.
The PN connection concept allows the terminal to serve as a supplementary main panel or secondary control panel in the documented thin-client arrangement.
The Siemens 6FC5403-0AA20-0AA1 SINUMERIK HT 8 Handheld Terminal may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
