How It Compares
| USB only industrial keypads | KY2175 supports USB, PS/2 and RS232, so older plant controllers are covered without a converter. |
|---|---|
| Painted steel keypads | SUS304 brushed stainless steel resists the corrosive air found in chemical and mining sites. |
| Thick key assemblies | The 14*14*1.5mm keys give a shallow build behind a cabinet door. |
Use Guide
- Choose rear or front mounting to match the cabinet door construction
- Wire the ordered interface and confirm each key reports
- Hold the supply at 5V ± 5%
- Keep ambient within -10℃~50℃ at the installed position
- Wipe the brushed face clean and avoid abrasive pads
