Product Overview
KY2088B is a 16 key numeric metal keypad with a front panel of 87.5*91.5 mm and an overall size of 138*95 mm, rated IP65 against water and dust. The compact layout is aimed at ticket vending machines, kiosks and self service payment machines where only digits and a few control keys are needed. Operation force is 220g±20g with a 0.45mm key trip for fast repeated entry.
- A 16 key numeric layout keeps the fascia cutout small at 87.5*91.5 mm
- IP65 sealing protects against rain and washing on outdoor ticket machines
- 220g±20g operation force with 0.45mm travel supports rapid digit entry
- Three interface options cover USB, PS/2 and RS232 hosts
- Stainless steel water and vandal proof design resists attack on street machines
Application Scenarios
- Ticket vending machines in transport hubs
- Self service payment machines outdoors
- Information kiosks needing numeric entry only

How It Compares
| Full metal keyboards | A 16 key pad needs only an 87.5*91.5 mm front panel on a crowded fascia |
|---|---|
| Plastic numeric keypads | Stainless steel water and vandal proof construction survives street installation |
| Single interface keypads | USB, PS/2 and RS232 are all available from the same model |

- Select USB, PS/2 or RS232 at order stage
- Provide DC5V±5% and confirm the port supplies under 150mA
- Keep operation within -20℃~55℃
- Check gaskets after service to maintain the IP65 rating
