Backlit Keyboard
KY3088-LP Backlit Metal Numeric Keyboard
KY3088-LP is a backlit stainless steel numeric keyboard built into a 140*135 mm panel for self-service terminals that are used after dark.
Product Overview
KY3088-LP is a backlit stainless steel numeric keyboard built into a 140*135 mm panel for self-service terminals that are used after dark. LED illumination sits behind stainless steel buttons so the legends stay readable without a separate lamp in the enclosure. It suits integrators who need a sealed numeric entry block that survives washdown and rough public handling.
- LED backlighting keeps the numeric block usable on unlit forecourts and night shift lines
- IP65 rated front face lets operators hose or wipe the panel between shifts
- Square 140*135 mm footprint drops into compact terminal fascias without redesigning the door
- Durability of 2 Million actuations per key reduces field swap frequency
- One part number covers USB, PS/2 and RS232 so the same keypad fits several controller generations
- Key legends produced by laser or etching so they cannot rub off under gloved use
Application Scenarios
- Unattended payment kiosks that stay live overnight
- Vending machines placed in poorly lit lobbies and corridors
- Self-service terminals in transport and automotive service areas
- Pharmaceutical and medical dosing stations requiring wipe-down surfaces
- Oil and gas field enclosures where the operator wears gloves
- Agricultural weighing and dispensing points exposed to dust
Who It Is For
- Kiosk and terminal OEMs specifying a sealed numeric input block
- Industrial automation integrators replacing plastic keypads
- Medical equipment builders needing a cleanable entry surface
- Transport ticketing suppliers standardising on one keypad across fleets
Problems It Solves
- Plastic numeric pads crack and let liquid into the terminal after vandalism
- Printed legends wear away and force early panel replacement
- Operators mis-key values on unlit panels at night
- Mixed controller interfaces force buyers to stock several keypad variants
Technical Features
- Stainless steel button heads on a stainless steel front panel
- LED backlit legend area behind each key
- Power supply DC5V±5% with working current below 150mA
- Interface options of USB, PS/2 and RS232
- Operating temperature range of -10℃~55℃ and storage range of -30℃~85℃

How It Compares
| Plastic membrane numeric pad | Stainless buttons resist prying and scraping that split a moulded pad |
|---|---|
| Non-backlit metal numeric keypad | LED illumination removes the need for an external lamp inside the fascia |
| Full size desktop keyboard | A 140*135 mm block frees panel area where only digits are entered |
Use Guide
- Confirm the cutout suits the 140*135 mm panel before ordering mounting hardware
- Choose rear mounting where the fascia must stay flush outside
- Supply DC5V±5% from the terminal harness and allow for under 150mA
- Keep ambient within -10℃~55℃ during operation
- Clean the stainless face with a damp cloth rather than abrasive pads
