KY-TB-38-C1 Stainless Steel Panel Keyboard With Mechanical Waterproof Switches
KY-TB-38-C1 is a panel mount keyboard built on a SUS304 stainless steel front plate with individually sealed mechanical switch buttons.
Product Overview
KY-TB-38-C1 is a panel mount keyboard built on a SUS304 stainless steel front plate with individually sealed mechanical switch buttons. It is specified by integrators who need an input surface that survives washdown, grit and deliberate abuse on an unattended terminal. Each key is a discrete waterproof switch rather than a membrane dome, so a single damaged key never disables the panel.
- SUS304 stainless steel panel resists corrosion and stands up to anti-riot service on exposed enclosures
- Waterproof stainless steel mechanical switch buttons keep liquid out of the switch body itself
- Durability rated at >2 million times so key replacement is not part of the annual service plan
- Draws only +5V DC @ 30mA, which leaves headroom on crowded terminal power budgets
- USB/PS/2 output drives Windows XP through Windows 10 plus Linux, Ubuntu and Android without a driver package
- Top to bottom panel fixed assembly lets the unit be serviced from the front of an installed cabinet
Application Scenarios
- Outdoor self-service terminals exposed to rain and wash cycles
- Access control panels where the keyboard is the only user touchpoint
- Machine control stations in plants with airborne coolant mist
- Public transport ticketing enclosures subject to vandalism
- Cold-side installations operating down to -10℃
Who It Is For
- Kiosk OEMs replacing plastic keyboards that fail field warranty
- Machine builders integrating an operator panel into a steel cabinet
- Facility contractors retrofitting public terminals
Problems It Solves
- Membrane overlays that tear and let moisture reach the circuit
- Keyboards that fail entirely after one key is damaged
- Plastic bezels that crack under impact on street level equipment
- Drivers and OS restrictions that block a mixed Windows and Linux fleet
Technical Features
- Discrete waterproof mechanical switch per key rather than a shared membrane layer
- ∅16mm round key head sized for gloved operation
- 1.5mm key trip with 1.5N ± 10% actuation force for confirmable feedback
- Power supply 5V±5% with working current of +5V DC @ 30mA
- Operating range -10℃~45℃ with 20%~85% relative humidity tolerance
- Storage range -30℃~85℃ covers unheated warehousing and sea freight

Manufacturing Process
- Sheet metal blanking and panel forming of the SUS304 front plate
- CNC machining of the ∅16mm key apertures
- Surface brushing and passivation of the stainless panel
- Switch seating and waterproof button assembly
- Wiring, USB/PS/2 harness termination and potting
Quality Control
- Key force sampling against the 1.5N ± 10% specification
- Key trip measurement to confirm 1.5mm travel
- Continuity and enumeration test on both USB and PS/2 output
- Temperature soak check across the -10℃~45℃ operating band
Customisation Options
- Key legend content by laser or etching
- Layout and key count changed to suit the host panel
- Cable length and connector type for USB or PS/2
- Panel cutout dimensions matched to an existing enclosure
- Logo added to the stainless panel
How It Compares
| Membrane keypad overlay | Sealing here is at each mechanical switch, so a scratched surface does not open a moisture path into the electronics |
|---|---|
| Plastic panel keyboard | The SUS304 plate is anti-riot and anti-corrosion where ABS bezels crack and yellow outdoors |
Use Guide
- Cut the panel aperture before fitting, since the unit mounts from top to bottom as a panel fixed assembly
- Confirm the host supplies 5V±5% before connecting
- Select USB or PS/2 at integration; both interfaces are supported
- Clean the stainless face with a non-abrasive cloth to preserve the brushed finish
- Keep long term storage inside -30℃~85℃
