| Plastic labelled keypad | Etched stainless steel labels do not rub off under public use |
Use Guide
- Send final label wording before etching as it is permanent
- Keep label text short enough to remain legible at the cap size
- Power from 5V±5% within the <150mA budget
- Operate within -10℃~50℃ and store within -30℃~85℃
- Choose rear or front mounting to suit the fascia thickness
