KY3088BS Metal Pin Pad With Flat 0.45mm Keys
KY3088BS is a metal pin pad that combines a 87.5*91.5 mm key face with a wider 138*95 mm body, so the mounting flange spreads across the fascia while the key field stays compact.
Product Overview
KY3088BS is a metal pin pad that combines a 87.5*91.5 mm key face with a wider 138*95 mm body, so the mounting flange spreads across the fascia while the key field stays compact. Flat keys with a 0.45mm trip resist prying and are easy to wipe clean. Hardware encryption covers PIN encryption, MAC calculation and data encryption and decryption.
- 138*95 mm body gives a broad fixing face around a compact 87.5*91.5 mm key area
- Flat 0.45mm key trip leaves little edge for tampering or dirt to catch on
- Hardware encryption chip handles PIN, MAC and data encryption
- 2*4 Function keys (FDK) for menu selection beside the screen
- MAC, DES(3EDS) and SM4 algorithm support
- USB, PS/2 or RS232 at DC5V±5% and under 100mA

Application Scenarios
- Automatic Teller Machine PIN entry
- Ticket Vending Machine payment modules
- Kiosk card payment positions
- Parking Solution pay stations
Who It Is For
- ATM and parking terminal manufacturers
- Payment kiosk integrators
- OEMs needing a wide mounting flange in a thin fascia
- Developers requiring SM4 alongside DES
Problems It Solves
- Narrow pin pad bodies that do not give enough fixing area in a sheet fascia
- Raised keys that collect dirt and can be levered at unattended machines
- PIN data passing through host software
- Different algorithm requirements between markets
- Hosts that only offer a serial port
Technical Features
- Stainless steel buttons in a water and vandal proof compact layout
- Hardware Encryption model with a security chip, plus a non-encryption model option
- Key trip 0.45mm with operation force 2~3N
- Durability ≥2 Million operations
- Password length 4-12 Bit and key length 8/16/24 bit
- Compatible with Window XP, Window 7, Window 10, Linux, Ubuntu and Android

How It Compares
| KY3088X encrypting pin pad | KY3088BS uses flat keys with a 0.45mm trip and a wider 138*95 mm body, where KY3088X has a 1.5 mm trip in a 95*117 mm body. |
|---|---|
| KY3088B metal pinpad | Both share the 87.5*91.5 mm key face and 0.45mm trip; KY3088BS is 138*95 mm overall against 140*95 mm for KY3088B. |
| Standalone PIN entry device | This is a panel-mount module for building into your own terminal rather than a separate desktop unit. |
Use Guide
- Cut the key aperture to 87.5*91.5 mm and allow the 138*95 mm flange to seat flat
- Confirm whether the encryption or non-encryption model is required
- Define the algorithm set before production
- Supply DC5V±5% with under 100mA available
- Operate within -20℃~55℃ and store within -30℃~85℃
