connectortype

Connectortype is a designation used to describe the interface and mating geometry of a connector in a system. It identifies the electrical and mechanical characteristics that define how two components are physically connected and how signals or power are transmitted across the interface.

In engineering practice, connectortype helps standardize documentation, BOMs, and CAD models by grouping connectors into families and standards (for example USB, PCIe, SATA, or board-to-board mezzanine connectors). The connectortype typically implies attributes such as the number of positions, pin pitch, gender (plug or receptacle), mounting style (surface mount, through-hole, or panel), latch or polarization features, and the expected electrical ratings (voltage, current, contact resistance).

In software and data models that describe hardware, a connectortype field enables validation and automated checks for compatibility, cross-referencing parts, and ensuring correct mating with the corresponding receptacle. Real-world usage includes specifying the connectortype in product drawings, engineering change orders, and supply chain data to prevent mismatches during assembly or repair.

Common connector families illustrate the breadth of connectortype options, including USB-C, HDMI, RJ45 (Ethernet), PCIe edge or card-edge, circular DIN, and common wire-to-board families such as JST, Molex, or TE Connectivity series. When selecting a connectortype, designers consider electrical requirements, mechanical fit, environmental protection, and industry standards and certification.
