KY3688A Metal EPP With 145*100 mm Braille Keypad
KY3688A is a metal EPP with a large 145*100 mm keypad in #304 stainless steel, giving wide key spacing and a defined layout that includes braille.
Product Overview
KY3688A is a metal EPP with a large 145*100 mm keypad in #304 stainless steel, giving wide key spacing and a defined layout that includes braille. It is certified to PCI 1.3 along with CE, ROHS, FCC, IP65 and IK7, and connects over an RS232 Serial Port with MK/SK key management and remote key loading. The POI is intended for use in both attended and unattended positions.
- 145*100 mm keypad gives generous key spacing for accessible PIN entry
- PCI 1.3 certification with CE, ROHS, FCC, IP65 and IK7
- ESD rating of 8K for exposed outdoor and forecourt positions
- MTBF greater than 42950 with a key press life of 2 millions
- Remote key loading with 16 keys under MK/SK management
- Wide operating temperature range of -40°C ~ 105°C

Application Scenarios
- Attended payment counters requiring a PED class device
- Unattended terminals in exposed outdoor positions
- ATM and self-service payment machines with a large PIN bay

How It Compares
| KY3688C metal PCI EPP | KY3688A is the larger 145*100 mm device certified to PCI 1.3, while KY3688C is 87.5*91.5 mm at PCI 3.0. |
|---|---|
| KY2160A metal encrypting pin pad | KY3688A is a certified PED class EPP with MK/SK key management and remote key loading rather than a general encrypting pin pad. |
| Smaller EPP modules | The 145*100 mm face provides wider key spacing where accessibility drives the specification. |
Use Guide
- Confirm PCI 1.3 is acceptable for your scheme before specifying
- Size the bay to the 145*100 mm device
- Provide an RS232 Serial Port and 5.0V ±10% supply
- Maintain the 3.0V ±10% battery as part of scheduled service
- Agree the remote key loading process with your key management host
