- Logistics handling stations
- Process plant operator panels
Who It Is For
- Cold chain equipment builders
- Outdoor terminal manufacturers
- Industrial automation integrators
- Process control panel makers
Problems It Solves
- Standard keypads stiffen or fail below freezing
- Water reaches the switch layer on exposed fronts
- Legacy controllers expect RS232 rather than USB
- Printed legends peel in cold wet conditions

How It Compares
| Standard industrial keypads | Operation from -40 degrees C extends use into freezer and winter outdoor sites |
|---|---|
| USB only keypads | RS232 support connects to controllers with no USB host |
| Printed legend keypads | Etched silk screen content stays readable after cold wet cleaning |
Use Guide
- Confirm the host offers an RS232 port before ordering
- Operate between -40 and 45 degrees C
- Store units between -40 and 85 degrees C
- Mount from the rear or the front as the fascia allows
- Supply 5V plus or minus 5 percent with headroom above 150mA
