Product Application
6FC5403-0AA20-0AA1 presents SINUMERIK screens on a 7.5-inch VGA touch display and places machine keys, enabling control and emergency-stop functions at the operator's working position.
The no-handwheel order number separates this terminal from 6FC5403-0AA20-1AA1, which is the HT 8 variant supplied with a handwheel.
The handheld format supports close-to-process observation and input while the machine-side connection box completes the installation interface for the enabling device and emergency-stop circuit.
Connections and Operator Controls
The terminal operates from 24 VDC and consumes no more than 13 W. Its IP65 front protection depends on an intact enclosure, cable and machine-side connection arrangement.
Basic PN and Plus PN connection-box options provide different emergency-stop override arrangements, so the installed box belongs to the machine design rather than the handheld order number alone.
The terminal is supplied through the documented connection accessories, and the selected box variant must preserve the machine's safety-circuit behavior when the handheld unit is disconnected.
