The NCST12FR390GTRF is a 12mm pitch, 390 contact, right angle, surface mount, pin-in-paste type, stacked array D-Subminiature connector manufactured by Nichicon Corporation. The connector has three rows of contacts, two top and one bottom, on a 0.5mm pitch grid where each contact has 0.20mm square pin terminals. The contact pitch is pitch-compatible with the existing ST14 series connectors and can provide a space-saving benefit by reducing the distance between the mounting holes of the connectors. The NCST12FR390GTRF connector is designed for a wide range of applications including home appliances, industrial machinery, and network devices.
