KY2122-3 is a 20 key numeric keypad in 304 stainless steel that reports as USB HID, so it works on a terminal PC without driver work.
Product Overview
KY2122-3 is a 20 key numeric keypad in 304 stainless steel that reports as USB HID, so it works on a terminal PC without driver work. The 107.3*89.8 mm front panel and overall footprint are identical, which keeps the cutout drawing simple. It is intended for kiosks, access control and machine panels that need extra function keys beyond a 12 key pad.

- USB HID output with other interfaces customizable for legacy controllers
- IP65 waterproof and vandal-proof construction for unattended sites
- Front panel and overall dimensions both 107.3*89.8 mm for a flush fit
- 2,000,000+ keystroke lifetime under public duty
- Layout customized for free so the key field matches your application
