This Product Selection Guide contains information to help select products in the Human Machine Interface (HMI) category on DigiKey.com
Human Machine Interfaces such as operator panels, touchscreens, keyboards, mice, and gamepads allow direct, physical input of data from the operator. Other terms for human-machine interfaces are man-machine interface (MMI) and, when the machine in question is a computer, human–computer interface. Additional UI layers may interact with one or more human senses including: tactile UI (touch), visual UI (sight), auditory UI (sound), olfactory UI (smell), equilibrial UI (balance), and gustatory UI (taste).
SelectionCharacteristics
Type: Indicates the style and configuration of the device.
Size - Display: The diagonal length from one corner to the opposite corner of the device’s display.
Display Type: Indicates the color scheme of the display.
Case Color: The dominant color of the device.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Ingress Protection: IP (Ingress Protection) ratings such as (IP20, IP65, IP67, etc.) define how likely water and dirt will get into the system. The first number represents dirt and solid contaminants while the second represents water and liquids.
IP Ratings
| Solids | Liquids | |
|---|---|---|
| 1 | Protected against solids larger than 50mm. | Protected against vertically falling drops of water. Limited Ingress permitted. |
| 2 | Protected against solids larger than 12.5mm. | Protected against vertically falling drops of water with the enclosure tilted up to 15 degrees from vertical. Limited ingress permitted. |
| 3 | Protected against solids larger than 2.5mm. | Protected against spraying water up to 60 degrees from vertical. Limited ingress permitted for 3 minutes. |
| 4 | Protected against solids larger than 1mm. | Protected against water splashed from any direction. Limited ingress permitted. |
| 5 | Protected against dust. Limited ingress of dust permitted. | Will not affect operation of equipment 2-8 hours. Protected against jets of water. Limited ingress permitted. |
| 6 | Dust tight. No ingress of dust 2-8 hours. | Protected against powerful jets of water. Limited ingress permitted. |
| 7 | ______________________ | Protected against the effects of immersion in 15cm-1m for 30 minutes. |
| 8 | ______________________ | Continuous immersion in water up to 3m for long periods of time. |
| 9 | ______________________ | Protected against high pressure jets of hot water. (30 seconds) |
| 9K | ______________________ | Protected against high pressure jets of hot water. (2 minutes) |
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Features: These are different capabilities or properties of the device such as a memory card interface or wireless connectivity.
For Use With/Related Products: Defines other part types, numbers, or series with which this product is designed to be used.
