Three-Row D-Sub Connectors Deliver Reliable High-Density Signal Transmission

Three-row solder-type D-Sub Connectors are high-density industrial connection components widely used in industrial automation, video equipment, medical devices, communications, and instrumentation. Their three-row contact layout, solder-wire termination, and metal shielding provide reliable multi-channel signal transmission in compact equipment.

High-Density and Reliable Connection

Compared with conventional two-row D-Sub connectors, the three-row design accommodates more contacts within a compact housing. Common 15-pin, 26-pin, and 44-pin configurations can support video, control, power, and grounding circuits.

The solder-wire design allows cables to be directly soldered to the terminals, providing secure connections with good resistance to vibration and mechanical stress. This makes the connectors suitable for industrial machinery, vehicle electronics, and control equipment.

Effective EMI Shielding

The metal D-shaped shell helps reduce electromagnetic interference from motors, power supplies, and inverters, supporting stable signal transmission in sensitive applications such as medical instruments, industrial displays, and precision equipment.

The polarized housing also helps prevent incorrect mating, while locking screws provide additional mechanical stability during vibration and repeated use.

Wide Application Range

Three-row D-Sub connectors offer a practical combination of high-density wiring, secure termination, EMI shielding, and mechanical protection for industrial and electronic equipment.
