These DB15 right angle connectors are designed to be mounted on printed circuit boards. All 15 pins and two mounting tabs (locking forks) extend through the circuit board, providing a convenient and sturdy connection. These DB15 connectors have 2 rows of pins (‘standard’ density) rather than 3 rows of pins (high density). For DB15HD 3-row connectors,
These connectors are the 0.318″ set back style. This means that the distance between the connector face and the closer row of pins is 0.318″. See the drawing below.
