KY2100A 16 Key SUS304 Metal Keypad With 4x4 Matrix
KY2100A is a 16keys SUS304 stainless steel keypad arranged as a 4×4 Matrix for gas station and access control terminals.
Product Overview
KY2100A is a 16keys SUS304 stainless steel keypad arranged as a 4×4 Matrix for gas station and access control terminals. Keys are etched in black text and embossing is available so numeric entry stays readable and tactile outdoors. It is intended for OEMs who need a vandal proof anti corrosion numeric input in a matrix arrangement.
- 4×4 Matrix layout maps directly to standard numeric entry firmware
- SUS304 stainless steel keypad and keys resist corrosion at fuel forecourts
- Black text etching keeps legends permanent
- Embossing is available for tactile identification of keys
- USB PS/2 and RS232 support covers pump and access controllers
- Working current under 150mA on a 5V plus or minus 5 percent supply
Application Scenarios
- Gas station pump and payment terminals
- Access control entry points
- Outdoor numeric code entry stations
- Self service fuel kiosks
- Industrial machine numeric entry
- Unattended terminals needing matrix output
Who It Is For
- Fuel dispenser and forecourt equipment makers
- Access control system integrators
- Outdoor terminal manufacturers
- Industrial machine builders
Problems It Solves
- Fuel vapour and weather corrode ordinary keypads
- Printed numbers disappear from heavily used entry pads
