This Product Selection Guide contains information to help select products in the Lighting Control category on DigiKey.com
Products in the lighting control family are used for turning lighting devices such as street lamps on or off, and/or communicating the operational status of a controlled lighting agent to some controlling entity. Examples include photocell-based devices that provide a contact closure output when ambient light levels fall below some specified level, to devices that implement powerline communications protocols to allow control by a centralized agent.
SelectionCharacteristics
Type: Indicates the style and configuration of the device.
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.
Number of Slots/Relays: Indicates how many control devices that can be accepted and how many come with/installed.
Circuit: Describes device function in terms of a number of poles and throws, as is typical for mechanical switches. For more information please see: Switch Basics, Examples of Pole and Throw
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) |
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.
