sixpin

Sixpin refers loosely to any connector or device configuration that uses six electrical contacts. It does not denote a single universal standard, but rather a category of six-pin formats used across various industries. Because many different six-pin families exist, the exact pin arrangement, shell shape, and electrical specifications vary between implementations.

Common examples include six-pin DIN connectors, which appeared in older audio and data equipment, and six-pin mini-DIN connectors, such as the 6-pin PS/2-style variants used on some keyboards and other peripherals. In computing hardware, the six-pin PCIe power connector is a well-known six-pin configuration inside a rectangular housing that can supply power to graphics cards, typically up to about 75 watts. Automotive and industrial equipment also employ six-pin circular or rectangular connectors for sensors, control modules, and other interfaces, often with differing pitch and locking mechanisms.

Key design characteristics of six-pin connectors include pin count, pinout, shell size, polarization to prevent misalignment, and whether the connection is soldered, crimped, or cable-to-cable with a locking latch. Compatibility is not guaranteed across different six-pin families; users must ensure that both the mating plug and receptacle share the same standard, pitch, and pinout.
