KY2070A 12 Keys Stainless Steel Keypad With 3X4 Matrix Option
KY2070A is a 12 KEYs stainless steel keypad that can be supplied as a USB device or as a plain 3X4 matrix for direct connection to a customer controller.
Product Overview
KY2070A is a 12 KEYs stainless steel keypad that can be supplied as a USB device or as a plain 3X4 matrix for direct connection to a customer controller. The SUS304 panel is described as anti-riot and anti-corrosion, and the layout itself can be customized. It is the simplest way to add numeric entry to a board-level design.
- 3X4 matrix output connects straight to your own MCU without a USB stack
- USB build is available when the host expects a standard keyboard device
- 12 KEYs keep the cutout small on narrow fascias and door stations
- Layout can be customized rather than fixed to a telephone keypad order
- Key strength 3N ± 10% prevents accidental presses in public areas
- Durability >2 million supports frequent daily code entry
Application Scenarios
- Door entry and intercom code panels
- Board-level embedded designs needing a matrix keypad
- Vending and locker code entry
- Machine setpoint entry on compact controllers
- Gate and barrier keypads in car parks
Who It Is For
- Embedded hardware designers needing a matrix input
- Access control and intercom manufacturers
- Locker and vending equipment builders
- Integrators upgrading plastic numeric pads
Problems It Solves
- USB-only keypads force a host stack onto simple microcontrollers
- Standard 12 key layouts do not match the product's symbol set
- Plastic keypads on shared doors wear and discolour
- Light-action keys trigger false entries at busy entrances

Manufacturing Process
- Panel punching of the 12 key apertures
- Brushing of the panel face
- Etching of the customized layout legends
- Matrix or USB controller assembly
- Continuity and output verification
Quality Control
- Matrix row and column continuity tested per unit
- Key strength sampled against 3N ± 10%
- USB enumeration checked on Windows and Linux
- Panel finish and etch legibility inspected
Customisation Options
- Layout customized rather than a fixed keypad order
- USB build or bare 3X4 matrix harness
- Etched legends including non-numeric symbols
- Panel outline and fixing pattern to drawing
- Rear or front mounting hardware
How It Compares
| USB-only metal keypad | The 3X4 matrix option removes the need for USB host support on a small controller |
|---|---|
| 16 key metal keypad | 12 KEYs fit narrower fascias where only digits and two function keys are required |
| Plastic matrix keypad | A SUS304 panel keeps its finish and legends on shared public doors |
Use Guide
- Decide between USB and 3X4 matrix before ordering as the controller differs
- For matrix builds, confirm your scan timing and pull-up arrangement
- Provide 5V±5% and allow up to 150mA on interfaced versions
- Cut the aperture to the supplied outline for rear or front mounting
- Operate within -10℃~50℃
