67 Key Metallic Keyboard With Braille KY-PC-NT3 BR
KY-PC-NT3(BR) is a 67 key stainless steel keyboard with Braille marked buttons for terminals that must be usable by visually impaired operators.
Product Overview
KY-PC-NT3(BR) is a 67 key stainless steel keyboard with Braille marked buttons for terminals that must be usable by visually impaired operators. The 330*100 mm front panel mounts from the rear so only the metal face is exposed at a kiosk or ticket machine. USB and PS/2 are both available, and the assembly is sealed to IP65.
- Braille button keys make self-service terminals usable without sighted assistance
- 67 keys give a full alphanumeric entry set in a 330*100 mm panel width
- IP65 sealing and 304 stainless steel resist water, dust and attempted vandalism
- Rear panel mount leaves no exposed fixings for tampering
- 2,000,000+ keystroke lifetime for high traffic public installations
- Laser or etching key labeling holds up better than printed legends
Application Scenarios
- Accessible ticket and information kiosks in transport hubs
- Access control and door entry systems
- Self-service payment kiosks
- Vending machines and car wash equipment
- Fuel dispensers and parking terminals
- Banking, medical and public outdoor terminal devices
Who It Is For
- Public transport ticketing integrators
- Banking and ATM terminal builders
- Kiosk manufacturers with accessibility requirements
- Government and municipal terminal suppliers
Problems It Solves
- Accessibility rules require tactile marking, which the Braille button keys provide directly on the metal
- Printed legends wear off in public use, so labeling is laser or etched
- Outdoor panels ingress water, so the keyboard is IP65 rated
- Legacy terminals lack USB, so PS/2 is available on the same unit
