22 Key Keyboard Touchpad Mouse KY3178A
KY3178A brings 22 SUS304 brushed stainless steel keys and a touchpad mouse together in one rear mounted panel for unmanned terminals.
Product Overview
KY3178A brings 22 SUS304 brushed stainless steel keys and a touchpad mouse together in one rear mounted panel for unmanned terminals. It is used where an operator needs both entry keys and a cursor but the fascia has room for only one device. USB output and support for Windows, Linux, Ubuntu and Android make host integration straightforward.
- 22 keys and touchpad pointing on one rear mounted panel save fascia space at unattended terminals
- SUS304 brushed stainless steel panel is explosion-proof and corrosion-resistant
- Laser-etched black characters stay readable after long public service
- Durability >2 million presses for continuously used self-service machines
- Working current <150mA suits terminals with tight power budgets
- Operation temperature -20℃~65℃ covers unheated kiosks and outdoor cabinets
Application Scenarios
- Bank self-service deposit and withdrawal machines
- Self-service form printing and query machines
- Public information query devices and automated monitoring
- Mine safety detection and coal mine equipment
- Industrial PC numerical control platforms and instrument testing equipment
- Fixed offshore platforms and military control consoles
Who It Is For
- Banking self-service equipment manufacturers
- Telecommunications terminal suppliers
- Industrial PC and CNC platform builders
- Offshore and mining equipment integrators
Problems It Solves
- Separate keyboard and mouse cutouts do not fit slim terminals, solved by the combined panel
- Public terminals attract abuse, so the panel is explosion-proof SUS304 brushed steel
- Printed characters rub off in heavy use, so characters are black and laser-etched
- Terminal power budgets are tight, met by a working current below 150mA
Technical Features
- 22 keys with key sizes 10*10*2.0mm and 14*14*2.0mm
- Key trip 0.45mm with operation force 2N+/-0.1N applied to the contact point
- Power supply 5V±5% and working current <150mA
- USB interface with rear mounting installation
- Durability >2 million presses
- MTBF >20000 hour and MTTR <30 minute

How It Compares
| Keyboard plus separate mouse | One rear mounted panel carries the 22 keys and the touchpad, needing a single cutout |
|---|---|
| Trackball equipped panels | A touchpad has no moving ball to clean, which suits dusty unmanned terminals |
| Plastic terminal keypads | SUS304 brushed steel construction is explosion-proof and corrosion-resistant at public machines |
Use Guide
- Cut the fascia for the panel body and install by rear mounting
- Supply 5V±5% and allow for the <150mA working current
- Connect USB to the terminal PC and verify cursor movement on the touchpad
- Specify etched character content before production
