The SIMATIC HMI 6AV6881-0AU14-0AA0 is the German-layout n-key rollover keyboard in the 6AV6881 desktop series. It pairs QWERTZ layout with the same 10-finger simultaneous input capability found on the US-layout 1AA0 model, in the same plastic TKL-105 form factor. For German-language control rooms where operators rely on fast multi-key sequences, this model delivers unrestricted key registration at a fraction of the INOX variant cost.

Why does n-key rollover matter for a German-layout HMI keyboard?

German keyboard shortcuts in industrial HMI software frequently combine modifier keys with alphanumeric and special character keys — Strg+Alt+Umschalt combinations for screen navigation, alarm management, or recipe selection. A 2-key rollover keyboard would drop the third simultaneous press, potentially missing a critical input. N-key rollover ensures every key in the chord registers, regardless of how many fingers are on the keyboard at once. For operators who work fast with keyboard-driven HMI software, this is a measurable productivity and safety advantage.

When is the plastic model the right choice?

This keyboard is designed for climate-controlled control rooms, not factory floors. Choose it when your station is in a clean, dry environment, your operators need unrestricted multi-key input, and budget matters. The plastic TKL-105 housing keeps cost at roughly one-seventh of the INOX variant. If your installation faces washdowns, vibration, or corrosive exposure, switch to the German-layout INOX model (0DB0) instead.

Frequently Asked Questions

What is the difference between 0AA0 and 1AA0?

0AA0 (this model) has German QWERTZ layout — Y and Z keys are swapped relative to QWERTY, and it includes umlaut keys (ä, ö, ü) and AltGr for accessing special characters. 1AA0 has US QWERTY layout. Both share the same plastic TKL-105 construction, n-key rollover, and USB interface.

Can I use this keyboard with a non-Siemens system?

Yes. The keyboard uses standard USB HID protocol and is compatible with Windows XP through Windows 10. It will function as a standard USB keyboard on any system that supports USB HID, though the n-key rollover advantage is most relevant in SIMATIC HMI software environments.
