Overview Manuals Key Layout USB Link Panel Fit Protection Limits

Features:

  • Seventy-eight mechanical short-stroke keys provide full CNC and alphanumeric input in a 19-inch panel format.
  • USB 1.1 carries keyboard data and the 5.25 V DC operating supply through the same connection.
  • The installed assembly separates an IP54 operator face from an IP00 rear inside the enclosure.
Siemens 6FC5203-0AF20-0AA1 provides a dedicated KB 483C key field for the SINUMERIK 840D sl operator station.

Its QWERTY layout and CNC key groups send commands through the integrated USB cable rather than through a separate keyboard controller.

Correct panel installation depends on the documented cutout and on keeping the unprotected rear section inside the cabinet.

Apter Power provides quotations, manuals, and model-matching support for Siemens 6FC5203-0AF20-0AA1.

  • Power draw: The USB path supplies 5.25 V DC for the documented 0.4 W load.

Cutout and Mounting Relationship

  • Panel opening: The documented cutout is 450 x 112.5 mm.
  • Front frame: The 483 x 133 mm face covers the cutout and presents the operator key field.
  • Rear depth: The 31 mm device depth extends behind the mounting surface.
  • Cable clearance: The rear enclosure must also leave space for the USB cable path.

Different Front and Rear Conditions

  • Operator side: The installed front is rated IP54 and operates from 0 to +45 °C.
  • Cabinet side: The IP00 rear operates from 0 to +55 °C only inside a suitable enclosure.
  • Storage range: The complete keyboard is stored between -25 and +55 °C.
  • Transport range: Transport conditions extend from -40 to +70 °C.
Description
Siemens 6FC5203-0AF20-0AA1 is a SINUMERIK KB 483C full CNC keyboard for the SINUMERIK 840D sl operator environment. Its 19-inch panel format and 78 mechanical short-stroke keys provide dedicated alphanumeric and CNC input at the machine-control station.

The key field on 6FC5203-0AF20-0AA1 uses a QWERTY layout so text entry, program editing, and command selection remain on a single sealed front assembly. Mechanical short-stroke switches generate the key signals without relying on a touch display for normal keyboard input.

Communication and power for 6FC5203-0AF20-0AA1 share the USB 1.1 Type B connection. The integrated 1.5 m cable carries the keyboard data to the host, while the complete USB path is limited to the documented 3 m link length.

Panel installation places the IP54 face of 6FC5203-0AF20-0AA1 at the operator side and leaves the IP00 rear inside the enclosure. The specified cutout, clamping surface, and separate front and rear temperature limits therefore apply to different sides of the same installed keyboard.

Technical notes
USB supplies both data and operating power to Siemens 6FC5203-0AF20-0AA1. The installed keyboard keeps its IP54 face outside the panel while the IP00 rear remains inside the enclosure.
