D-Sub connector
D-Sub connectors, also known as D-subminiature connectors, are a family of electrical connectors characterized by their distinctive D-shaped metal shield. This shield provides mechanical support, ensures correct orientation, and offers basic EMI/RFI shielding. These connectors are available in various shell sizes (e.g., DA-15, DB-25, DC-37, DD-5...
D-Sub connectors, also known as D-subminiature connectors, are a family of electrical connectors characterized by their distinctive D-shaped metal shield. This shield provides mechanical support, ensures correct orientation, and offers basic EMI/RFI shielding. These connectors are available in various shell sizes (e.g., DA-15, DB-25, DC-37, DD-50, DE-9) and pin counts, ranging from 9 to 78 positions. They support a wide range of signal types, including analog, digital, and low-power data transmission, with current ratings typically up to 5A per contact and voltage ratings up to 300V AC/DC. Common configurations include standard density and high density (HD) variants, with contact arrangements for solder, crimp, or insulation displacement termination. The robust design makes them suitable for applications requiring reliable, repeated mating cycles.
D-Sub connectors are extensively used in industrial automation, telecommunications, computer networking, and test equipment. In factory automation, they are found on PLCs, CNC machines, and servo drives for serial communication (RS-232, RS-422, RS-485) and I/O interfaces. They also appear in medical devices, aerospace instrumentation, and audio/video equipment. Their rugged metal shell and locking screw mechanisms (e.g., 4-40 UNC or M3 threaded inserts) ensure secure connections in high-vibration environments, such as production lines and control cabinets.
Our catalog includes a comprehensive range of D-Sub connectors, categorized by shell size and contact density. Key subcategories include standard density connectors (e.g., DB-9, DB-15, DB-25, DB-37, DB-50) and high density connectors (e.g., HD-15, HD-26, HD-44, HD-62, HD-78). We also offer accessories such as hoods, backshells, and locking posts. Article codes typically follow a pattern like "DS-XX-YY-ZZ", where XX denotes shell size (e.g., 09, 15, 25), YY indicates contact count, and ZZ specifies termination type (e.g., ST for solder, CR for crimp, ID for insulation displacement). For example, DS-25-25-ST represents a standard DB-25 connector with solder contacts.
