KY-FB-DT-A Explosion Proof Keyboard With Touchpad and 3mm Aluminium Base
KY-FB-DT-A is an embedded explosion-proof keyboard with 66 buttons, touchpad mouse function and an explosion-proof isolation grid.
Product Overview
KY-FB-DT-A is an embedded explosion-proof keyboard with 66 buttons, touchpad mouse function and an explosion-proof isolation grid. A 3mm aluminium alloy base plate stiffens the assembly behind the SUS304 face so it can be built into a console rather than sitting on a desk. It is supplied with certificates and carries the mark Ex ib IIC T6 Gb.
- Embedded format lets the keyboard become part of a sealed hazardous area console
- 3mm aluminium alloy base plate resists flexing and levering behind the panel
- Explosion-proof isolation grid and certificates supplied with the assembly
- Touchpad mouse function avoids a second certified device in the area
- Light 1.25Kg net weight compared with desktop explosion-proof units
- USB or PS/2 output suits both new and installed control PCs
Application Scenarios
- Downhole and coal mine equipment control consoles
- Petroleum and natural gas plant panels
- Chemical industry and metallurgy operator stations
- Electric power switchgear control desks
- Explosion-proof telephone and electrical equipment enclosures
Who It Is For
- Hazardous area console builders
- Mining equipment OEMs
- Oil and gas instrumentation contractors
- Power and metallurgy automation integrators
Problems It Solves
- Desktop keyboards cannot be built into a sealed hazardous area console
- Thin base plates let a panel keyboard flex and lose contact alignment
- Certification documentation is missing from generic industrial keyboards
- A separate mouse doubles the certification and cabling work

How It Compares
| KY-FB-DT-B desktop explosion proof keyboard | KY-FB-DT-A is embedded with a 3mm aluminium alloy base plate and 1.25Kg net weight, rather than a desktop unit at 2.15Kg. |
|---|---|
| Non certified industrial keyboards | This assembly carries Ex ib IIC T6 Gb marking, a safety grid and certificates for explosive atmospheres. |
| Keyboard with separate trackball | The touchpad is inside the certified assembly, so only one device needs approval and cabling. |
Use Guide
- Fit the keyboard from the bottom up with the bottom plate fixed into the console
- Install the explosion-proof isolation grid on the safe side of the wiring
- Connect by USB or PS/2 and verify all buttons and touchpad response
- Keep the working ambient inside -10℃~45℃
- Retain the test and certification documents with the plant records
