Product Overview
KY-3100A is a panel mount keypad carrying 35 buttons on a corrosion-resistant SUS304 brushed stainless steel face. Buyers choose it when a terminal needs a wide key field on a 12V rail and the etched legends must survive years of public fingers. Assembly is from top to bottom with the base plate fixed.
- Wide 35 button field lets numeric entry and command keys share a single cut-out
- Explosion-proof and corrosion-resistant SUS304 brushed face for exposed fascias
- Draws under 70mA, so several panels can share one 12V branch
- Etched characters are cut into the steel rather than printed on top
- Shallow 1.5mm thick keys allow a tight enclosure depth
- Rated beyond 2 millions times of key actuation
Application Scenarios
- Banking and financial equipment fascias
- Communication equipment racks with front panel entry
- Military equipment control stations
- Self-service terminals dispensing tickets or goods
- Access control posts needing numeric plus command keys
Who It Is For
- Terminal fascia design engineers
- Financial and payment equipment OEMs
- Telecom equipment manufacturers
- Government and defence panel suppliers
Problems It Solves
- Printed key legends disappear within a season on busy machines
- Small keypads force a second panel for command keys
- Corrosive or coastal air pits plated keypad surfaces
- Adding a 5V converter for an input device complicates a 12V design
Technical Features
- 35 button embedded panel with brushed SUS304 keys
- Laser etching available for black characters
- Power supply 12V plus or minus 5 percent, working current under 70mA
- Key size 14*14*1.5mm and key trip 0.45mm
- Operation force 3N plus or minus 10 percent
- USB interface across Window XP to Window 10, Linux, Ubuntu and Android
- Storage temperature -30 degrees C to 85 degrees C

How It Compares
| KY-3100B | Both carry 35 buttons on the same electrical platform, so choose by panel styling and fixing rather than performance. |
|---|---|
| Plastic ABS keypads | The brushed SUS304 face is corrosion-resistant and explosion-proof where plastic yellows and cracks. |
| Front fixed keypads | Top to bottom assembly with a fixed base plate keeps the load on the panel and the fixings out of reach. |
Use Guide
- Machine the fascia opening to the supplied panel drawing
- Insert from the top and secure the base plate before wiring
- Feed 12V ± 5% and verify the USB enumeration on the host
- Operate within -20℃~60℃ and store within -30℃~85℃
- Avoid solvent cleaners that attack the etched legends
