How It Compares
| Uniform key metal keypad | Mixed cap widths let operators identify key roles without looking |
|---|---|
| Rectangular key keypad | Keeps compact 14*14*1.5mm keys for the numeric field while enlarging only the function keys |
| Plastic keypad | Etched SUS304 keeps legends and finish through heavy industrial handling |
Use Guide
- Decide which functions deserve double-width caps before tooling
- Confirm the panel cutout covers the mixed key pitch
- Power from 5V±5% with under 150mA available
- Press double-width keys near their centre for consistent feel
- Store within -30℃~85℃ when equipment is out of service
