twopin

Twopin is a term that may refer to more than one concept or entity, depending on context. The most common technical usage describes a two-pin electrical connector: a simple two-terminal device used to link electrical circuits or devices. Two-pin connectors come in many forms and polarities and are used across consumer electronics, instrumentation, and hobby projects. They are typically designed for straightforward mating of two conductive pins with a matching receptacle, and many varieties are intended for low- to medium-power applications. The design emphasizes compact size, ease of assembly, and cost-effectiveness, with safety requirements varying by jurisdiction. In some catalogs and retail contexts, "twopin" is used as a shorthand in product naming to indicate a two-pin configuration, but the term is not a standardized designation on its own.

Beyond electronics, "Twopin" has appeared as a brand name or product label in unrelated fields, including entertainment and consumer goods. Because there is no single, authoritative definition, readers should rely on the context in which the term is used to determine its intended meaning.
