KY2140 is an encrypted digital keypad with 17 keys, built as an embedded device for financial equipment, communication equipment and machinery that needs secure numeric entry.
Product Overview
KY2140 is an encrypted digital keypad with 17 keys, built as an embedded device for financial equipment, communication equipment and machinery that needs secure numeric entry. The panel and keys are wire drawn SUS304 stainless steel, laser etched when the characters are black. Its short 0.45mm key stroke suits fast repeated code entry at a terminal.
- 17 key encrypted layout is aimed at secure code entry rather than general typing
- Wire drawn SUS304 stainless steel panel and keys are anti-riot and anti-corrosion
- Short 0.45mm key stroke supports fast repeated PIN and code entry
- 2N+/-0.1N contact force is firm enough to resist accidental presses
- Etched key content is made to customer requirements
- Embedded format drops into existing self-service terminal panels
Application Scenarios
- Financial equipment requiring secure numeric entry
- Communication equipment access panels
- Mechanical equipment operator code entry
- Self-service terminal equipment in public areas
