Product Overview
KY2122 is a water and vandal proof stainless steel keypad with a compact layout that is customized for free. Key labeling can be produced by laser or by etching, depending on the contrast and depth you need. The key field mixes 14*14*1.5mm and 21.5*15.5*1.5mm caps for numeric and function entry.
- Laser or etching key labeling lets you choose contrast against the brushed finish
- Water and vandal proof design suits unsupervised public positions
- Compact layout is customized for free rather than charged as tooling
- Mixed 14*14*1.5 and 21.5*15.5*1.5mm caps separate digits from functions
- Durability ≥2 million supports constant public operation
- Net weight 0.25Kg keeps the fascia load low
Application Scenarios
- Street-level access and intercom panels
- Public transport help and ticket points
- Laundry and locker payment terminals
- Building entrances in high-traffic housing
- Unattended service kiosks

How It Compares
| Etch-only metal keypad | Laser marking is also offered when you want a different contrast on the brushed face |
|---|---|
| Plastic vandal resistant keypad | Stainless steel caps do not shatter under a struck blow |
| Fixed layout keypad | The compact layout is customized for free instead of forcing a standard key order |
Use Guide
- Choose laser or etching based on the contrast you need at viewing distance
- Send layout requirements early since customization is included
- Supply 5V±5% within the <150mA budget
- Keep ambient within -10℃~50℃
- Wipe the panel clean rather than scraping deposits off the caps
