KeySonic ACK-3401U — Super Mini USB Keyboard, UK English, Black
75% compact80 keys1.6 mm travel2 m cable
The KeySonic ACK-3401U is a super mini keyboard: a full working layout squeezed into a 75% compact format with 80 keys, for desks where a full-size board simply does not fit or where the mouse needs to come closer to the shoulder. The keys use X-Type scissor membrane technology with KeySonic’s Soft Skin coating, giving 1.6 mm of travel and a 55 ±15 g pressure point — a short, light, laptop-like stroke — rated at around 5 million strokes per key. Three status LEDs cover Num, Caps and Scroll lock. It is wired USB, plug and play, powered from the port, with a generous 2 m cable, and it weighs just 216 g. KeySonic quotes 220 × 110 × 10 mm in its datasheet and 220 × 105 × 16 mm on the product page; we print both rather than choose. In the box: the keyboard and a manual.
Compatibility — check before buying:
Layout: UK English QWERTY has the tall Enter key, £ on Shift+3, and @ and " swapped compared with US layout. Letters and numbers are identical to US; if you need the US key shapes, ask us for the US International version. This is a wired USB-A keyboard, so there is nothing to charge or pair and it works in the BIOS and in boot menus. Understand what a 75% format costs you: there is no separate numeric keypad, and the function row and navigation keys are compressed, so if you spend the day in spreadsheets this is the wrong keyboard — ask us for a full-size one. There is no wireless option, no backlight, no media keys and no palm rest. KeySonic lists Windows and states Mac compatibility on the product page. It publishes no certifications, no N-key rollover figure and no USB report rate. Operating range is 0 to +55 °C at 0–90% humidity.
Best For
✓ Very shallow desks, counters and trolleys
✓ Point-of-sale and kiosk positions with little room
✓ Rack and server rooms where a small board lives on a shelf
✓ Users who want the mouse closer to the shoulder
✓ Second keyboards for laptops used at a desk
✓ Anyone who prefers a short, laptop-like key stroke

Frequently Asked Questions
Is there a number pad?
No. This is a 75% compact keyboard — 80 keys, no separate numeric block. If you do data entry, ask us for a full-size board or add a separate numeric keypad.
Why are there two sets of dimensions?
KeySonic’s datasheet and its product page publish different figures (220 × 110 × 10 mm and 220 × 105 × 16 mm). We print both rather than pick the one that suits us.
Does it work before Windows loads?
Yes. It is a wired USB keyboard, available in the BIOS and in boot menus.
Which layout is this part number?
This one is UK English. KeySonic publishes exactly three variants of the ACK-3401U: 60485 UK, 60382 German and 60383 US.
Singular Expert Insight
Buy this when the space is the constraint and the person does not live in a spreadsheet. If they do, the missing number pad will annoy them within a week — ask us for a full-size KeySonic or CHERRY instead. See our
keyboards.
Buyer’s Guide
Buy it if
You need a genuinely small wired keyboard with a full working layout and a long cable, in UK English layout.
Skip it if
You need a numeric keypad, wireless, a backlight, media keys, or published certifications.
Also consider
A separate USB or Bluetooth numeric keypad alongside it, or a full-size CHERRY DC 2000 if space turns out not to be the problem.
