20 Key Stainless Steel Matrix Keypad KY-2122-2
KY-2122-2 is a 20 key brushed stainless steel matrix keypad for equipment that reads a key matrix directly rather than a USB device.
Product Overview
KY-2122-2 is a 20 key brushed stainless steel matrix keypad for equipment that reads a key matrix directly rather than a USB device. The scratch-resistant panel and stable internal conductive structure keep keystroke feedback consistent through long continuous shifts. Connection modes are configured to the customer controller.
- Matrix output connects straight to an existing controller scan, with no HID stack required
- 20 key layout is customizable to match the equipment it is fitted to
- Brushed stainless steel panel gives wear resistance and corrosion resistance on machine fronts
- Stable internal conductive structure keeps keystroke feedback sensitive during long continuous operation
- Stainless steel casing blocks dust and splash to extend service life in tough environments
- Scratch-resistant finish keeps machine panels presentable after years of handling
Application Scenarios
- Industrial control cabinets
- Automation machinery operator panels
- Medical instrumentation control panels
- Cabinet control stations in production areas
- Equipment consoles requiring direct matrix input
Who It Is For
- Automation machine builders
- Control cabinet manufacturers
- Medical instrument makers
- Embedded controller integrators
Problems It Solves
- Adding a USB host to a simple controller is costly, so the keypad outputs a key matrix
- Dust and splash shorten keypad life on machine fronts, blocked by the stainless steel casing
- Generic layouts do not fit bespoke machinery, so the 20 key layout is customizable
- Intermittent contact disrupts operation, addressed by the stable internal conductive structure
Technical Features
- 20 key matrix key field
- Brushed stainless steel panel with wear and corrosion resistance
- Stable internal conductive structure for consistent keystroke feedback
- Dust and splash blocking stainless steel casing
- Connection modes configurable per client demand
- Customizable key layout for equipment matching

How It Compares
| USB keypads | Matrix output suits controllers that scan rows and columns directly without a USB host |
|---|---|
| Plastic matrix pads | The stainless steel panel and casing resist wear, corrosion, dust and splash on machine fronts |
| Fixed layout keypads | The 20 key layout is customizable so the pad matches the equipment rather than the other way round |
Use Guide
- Confirm the matrix row and column arrangement with your controller before order
- Fit the pad into the cabinet front and secure the casing
- Specify the key legends at order as they are applied during manufacture
- Wipe the brushed panel with a soft cloth to preserve the finish
