7polige

7polige is an adjective used in Germanic languages to describe objects that have seven poles or contact points. In technical contexts it is most commonly encountered in reference to seven-pole electrical or signal connectors and to product variants marketed as “7-polige.”

In practice, seven-pole connectors are used when multiple circuits must pass through a single interface. This is common in trailer and caravan electrical systems, where seven poles can carry lighting, signaling, and auxiliary power, as well as in certain automotive sensors and industrial control panels. The exact pinout and physical form of a seven-pole connector vary by standard and region, so manufacturers provide specification sheets to ensure compatibility between components.

Outside of connectors, the term can describe any object with seven structural poles or projections, but such usage is less common and typically avoided in formal technical writing in favor of precise geometry or function.

Etymology and usage notes: the term derives from the German word polig meaning “having poles,” combined with the numeral seven. 7polige is not a formal international standard term; its use appears mainly in catalogs, product descriptions, or colloquial references. When precision is required, the exact connector standard, pinout, and mechanical profile should be specified.
