KeySonic KSK-5031IN — IP68 Mini Silicone Keyboard with Touchpad, UK English
IP68 sealedBuilt-in touchpad220 mm mini body−20 to +70 °C
The KeySonic KSK-5031IN (28099) is a fully sealed silicone mini keyboard for places where a normal keyboard would not last a week: cold stores, wet production areas, workshops, ambulances, laboratories and clinical rooms. The entire surface is silicone and rated IP68 — dust-tight and protected against immersion — so it can be wiped with disinfectant or rinsed rather than thrown away. It packs 87 keys and an integrated 43 × 27 mm touchpad into a body just 220 × 110 mm and 10 mm high, weighing 248 g, so it fits on a trolley, a rack shelf or a control panel where a full keyboard simply will not go. KeySonic rates it for operation from −20 to +70 °C, which covers freezers as well as hot workshops. It plugs into any USB port and needs no drivers. This article number is the UK English layout in black.
Compatibility — check before buying:
Plug and play over USB, powered from the port, with the touchpad and keyboard both following standard HID — so it works on Windows, macOS and Linux without drivers. There is no numeric keypad and no backlight: this is a mini layout for control and data-entry tasks, not for writing documents. The silicone keys give a soft, damped keystroke with no click, which takes some getting used to and is not comfortable for all-day typing — choose it for the environment, not for the typing. It is wired; there is no wireless version of this article number. IP68 means it survives washing and immersion, but dry it before use and do not put it in a dishwasher or autoclave. 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.
Best For
✓ Cold stores and freezer areas, down to −20 °C
✓ Wet production lines, kitchens and food processing
✓ Laboratories and clinical rooms that must be disinfected
✓ Vehicles, trolleys and control panels with no space for a full keyboard
✓ Workshops with dust, swarf, oil and coolant
✓ Work done in gloves, where a mouse is impractical
Key Features
IP68 — clean it, do not replace it
Dust-tight and protected against immersion: wipe it with disinfectant or rinse it under a tap, dry it, and carry on working.
Touchpad built in
A 43 × 27 mm touchpad replaces the mouse entirely, so there is no second sealed device to buy, clean or lose.
Fits where nothing else does
220 × 110 mm and 10 mm high, 248 g — small enough for a trolley shelf, a rack drawer or a machine console.
Works from −20 to +70 °C
Rated for freezer temperatures as well as hot workshop air, which is where ordinary keyboards fail first.

Frequently Asked Questions
Can I wash it?
Yes. IP68 means dust-tight and protected against immersion, and the silicone body is designed to be wiped with disinfectant or rinsed. Dry it before use; do not put it in a dishwasher or autoclave.
Does it work in a freezer?
KeySonic rates it from −20 to +70 °C, so yes for cold-store use.
Is it comfortable for writing documents?
No. Silicone keys are soft and damped, and the mini layout has no numeric pad. It is built for hostile environments, not for speed typing.
Do I still need a mouse?
No. The 43 × 27 mm touchpad is built in, which also means one less thing to keep clean.
Singular Expert Insight
Choose the KSK-5031IN when space is tight and the cleaning routine decides the keyboard. If you need a full-size sealed board with a numeric pad, look at the KSK-8030IN instead — same protection, standard layout. Browse our other
keyboards or ask us to match an article number to your environment and layout.
