Honeywell ESD
You often hear manufacturers reference ESD when discussing scanners. In fact, on the Honeywell Granit datasheet you’ll see under the “Environmental” section on the back: ESD. ±20Kv air discharge, ±8KV contact discharge
What does it mean and why is it important?
- ESD – electrostatic discharge – is the sudden flow of electricity between two objects resulting from two conditions:
- Air Discharge. A high electrostatic field between two objects when they are in close proximity.
- Contact Discharge. Direct contact transfer of electricity between two objects at different potentials. This is similar to the above except you are injecting the shock directly into the computer. A typical example of this would be 20KV Air Discharge into a scanner vehicle mount. The mount in turn passes an 8KV shock to the scanner.
- Kv is a kilovolt – or 1,000 Volts. And a volt is…um…a unit of measurement to define voltage. Think of voltage, using a plumbing analogy, as water pressure.
