PC pin terminals or single post connectors are male gendered, single conductor devices, typically used on circuit boards. They are defined by the terminal type (double end, flanged, pc pin, single post), their terminal style (double end, flanged, pin retention, single end, smooth, wire), and their pin diameter or mounting hole diameter. Other parameters include overall length, mounting type (board edge, free-hanging, press fit, surface mount, through-hole), termination, etc.
