Key Features
Colour The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.	White
Depth The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.	35 mm
Environmental The environmental conditions under which the product is designed to operate safely and reliably, expressed as a temperature range in degrees Celsius and a relative humidity range in percent. Values are typically formatted like "0 °C to 40 °C – 10 % to 90 %" or similar.	, Operating Temperature -40 to 55°C - Humidity 20 to 85%
Ethernet LAN ports Represents the total count of Ethernet LAN (RJ‑45) interfaces available on a product. The value is an integer indicating how many physical Ethernet ports are present, regardless of speed or generation.	1
Height The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.	178 mm
Operating temperature The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.	40
Power adaptor type The classification of the power adaptor used with a device, indicating whether it is external or internal, its electrical interface (AC, DC, USB‑Charging, etc.), and any specific form such as integrated or travel adapters. This attribute helps buyers understand how the device receives power and what kind of connector or cable is required.	External
Relative humidity The range of relative humidity (expressed as a percentage) within which the product is designed to operate reliably. Values are given as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.	20 - 85%
Serial interface type The type of serial communication interface supported by the product, such as RS‑232, RS‑485, RJ‑45, or SATA. It indicates which physical connectors and protocols are available for data exchange with other devices.	RJ-45
Voltage The electrical potential difference that a device is designed to accept from its power source, expressed in volts (V). It indicates the nominal operating voltage for the product and helps users verify compatibility with local mains or battery supplies.	12/24 V
Width The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.	120 mm
