Overview Manuals Display & Control Safety Devices Power Path Environment

Features:

  • An 8-inch 640 x 480 color display carries the assigned SINUMERIK operator interface.
  • The portable IP65 enclosure combines viewing, command keys, emergency stop, and enabling control.
  • A 24 V DC connection supplies the terminal through the documented HT 8 connection hardware.
The machine interface displayed by Siemens 6FC5403-0AA20-0AA0 follows the connected SINUMERIK HMI rather than running as an independent controller.

Operator commands from 6FC5403-0AA20-0AA0 return through the handheld connection while the enabling and emergency-stop circuits remain part of their defined control paths.

The non-handwheel order code of 6FC5403-0AA20-0AA0 distinguishes it from the adjacent HT 8 version that adds a handwheel.

The Siemens 6FC5403-0AA20-0AA0 SINUMERIK HT 8 Handheld Operator Terminal may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Portable Machine Operation

  • VGA screen: The 8-inch color panel displays a 640 x 480 operator interface.
  • Local commands: Handheld keys transfer operator actions to the connected SINUMERIK system.
  • Mobile position: The cable-connected design lets the interface move within the documented operating area.
  • Variant check: This article is the HT 8 configuration without the handwheel option.

Emergency Stop and Enabling Paths

  • Emergency stop: The handheld command device must be integrated into the machine emergency-stop circuit.
  • Enabling control: The enabling button provides the documented staged operator-permission signal.
  • Connection box: The selected PN Basic or PN Plus hardware defines how the safety circuits are connected.
  • Circuit boundary: The terminal does not replace the required external safety evaluation and wiring.

Connection Hardware and Supply

  • Supply input: The HT 8 operates from a 24 V DC source delivered through its connection arrangement.
  • Consumption: The complete terminal draws no more than 13 W under rated operation.
  • Signal bundle: Display, key, and command-device conductors travel through the supported handheld cable path.
  • Accessory match: Connection module, box, and cable selection must match the installed SINUMERIK architecture.

Handheld Operating Limits

  • Housing: IP65 protection applies to the handheld terminal enclosure.
  • Operation: The permitted operating-air range is 0 to 55 C.
  • Transport and storage: The documented lower limit is -20 C and the upper limit is 55 C.
  • Humidity: Relative humidity may reach 95 percent only when condensation and icing are excluded.
Description
Siemens 6FC5403-0AA20-0AA0 is a SINUMERIK HT 8 handheld operator terminal for mobile machine operation. Its 8-inch VGA color display presents the assigned CNC interface while the handheld controls let the operator work from a position away from the fixed panel.

A 24 V DC supply powers 6FC5403-0AA20-0AA0, and the terminal consumes no more than 13 W. The connection arrangement carries display data, key information, and the control-device circuits through the supported HT 8 connection module or box rather than through a separate local power adapter.

The enclosure of 6FC5403-0AA20-0AA0 is rated IP65, so the handheld body resists the documented industrial environment while remaining portable. Its emergency-stop command device and enabling button belong to the machine safety circuit and must be wired through the correct connection-box variant.

Operation of 6FC5403-0AA20-0AA0 is bounded by the documented 0 to 55 °C range and by condensation-free use. This exact order number is the HT 8 version without the separate handwheel suffix used by the adjacent variant.

Siemens 6FC5403-0AA20-0AA0 is the HT 8 without the handwheel option; the adjacent handwheel model uses a different suffix.
Why can 6FC5403-0AA20-0AA0 remain off even when a nearby 24 V supply is present?
Power and terminal data for 6FC5403-0AA20-0AA0 pass through the supported HT 8 connection hardware, so verify the correct box, cable, and 24 V DC feed rather than using an unrelated adapter.
Why must the connection box be verified for 6FC5403-0AA20-0AA0?
The selected box for 6FC5403-0AA20-0AA0 determines the documented emergency-stop and enabling-circuit connection behavior.
Can 6FC5403-0AA20-0AA0 be treated as a standalone CNC controller?
No. The 6FC5403-0AA20-0AA0 is a handheld operator terminal that exchanges display and command data with the connected SINUMERIK system.
What environmental issue is excluded for 6FC5403-0AA20-0AA0?
