KY2161 24 Key Brushed Stainless Steel Keypad
KY2161 is a 24 key keypad on a brushed SUS304 stainless steel panel, supporting USB, PS/2 and RS232 output from one design. Key strength of 3N ± 10% and a 0.45mm key trip give a short positive action suited to rapid data entry.
Product Overview
KY2161 is a 24 key keypad on a brushed SUS304 stainless steel panel, supporting USB, PS/2 and RS232 output from one design. Key strength of 3N ± 10% and a 0.45mm key trip give a short positive action suited to rapid data entry. Etched button content is set to each customer requirement.
- 24 keys cover a numeric block plus function keys without a full keyboard footprint
- Three interface options on one model simplify spares across a mixed fleet
- 0.45mm key trip allows fast repeated entry without deep finger travel
- Brushed SUS304 hides fingerprints and scratches better than a mirror finish
- Rear or front mounting supports both new enclosures and retrofits
Application Scenarios
- Self service terminals with numeric and function entry
- Industrial control panels requiring serial connection
- Legacy equipment still fitted with PS/2 ports

Who It Is For
- Terminal manufacturers standardising on one keypad across interfaces
- Industrial integrators specifying panel mount keypads
- Service companies retrofitting failed plastic keypads
Problems It Solves
- Separate keypad models for USB, PS/2 and RS232 complicate stock holding
- Deep travel keys slow down high volume data entry
- Polished panels show every fingerprint in public use
- Bespoke legend requirements are refused by catalogue suppliers

Use Guide
- Choose front or rear mounting to match your enclosure cutout
- Confirm the host can supply 5V±5% at under 150mA
- Send etching artwork with the order so the legends are produced correctly
- Operate within -10℃~50℃ and store above -30℃
- Wipe along the brush grain to preserve the panel finish
