D-Sub connectors: reliable and versatile connection solutions
D-Sub connectors (D-subminiature connectors or D-sub connectors) are electrical connectors that are widely recognized for their distinctive D-shaped shell and multi-pin structure. Developed in the 1950s, D-Sub continues to provide reliable data, power, and signal connections today in a wide variety of applications, including industrial equipment, communications, medical, aerospace, and more. Known for their durability, flexible configurations and wide range of sizes, D-Subs are available at Nicomatic in a wide range of variations, making them the connectivity solution to meet the needs of any industry.
Features of D-Sub connector
D-Sub connectors have a D-shaped metal shell and a multi-pin structure, allowing for highly reliable connections in a variety of environments. The shielded metal shell prevents electromagnetic interference (EMI), ensuring a stable connection even in noise-sensitive environments.
Main features：
- Reliable connection: D-Sub design provides reliable connection even in environments where vibration and shock occur.
- Shield effect: Metal shell blocks EMI and protects data integrity.
- Flexible configuration: Multiple sizes, pin arrangements, and shell materials to choose from, suitable for a wide range of applications.
Types and uses of D-Sub connectors
D-Sub connectors come in standard density and high density variations, as well as different variations based on connector shape, pin count, and application requirements.
- Standard density D-Sub: Available in 9-pin to 50-pin configurations, most commonly used for PC connectivity and peripheral communication.
- High Density D-Sub:In order to fit more pins into a compact space, it has 15 to 78 pins and is used in communication equipment and measurement equipment.
- Crimp type/solder type: Mounting methods include crimping, soldering, and PCB mounting, providing flexible connection options.
- WaterproofD-Sub: Waterproof D-Sub is also available for outdoor use or humid environments.
Main uses of D-Sub
D-Sub connectors are suitable for a wide range of applications, including:
- Industrial equipment: Reliably transmits data and power, supporting stable operation of machines and production lines.
- Computer and communication: Used since ancient times to connect computer serial ports and printers, and is still used as a highly reliable connection in the communications field.
- Medical equipment: Suitable for connecting medical devices that require stability and reliability, and used in diagnostic equipment and monitoring systems.
- Aerospace and defense: Reliability that withstands signal and power transmission under harsh conditions and meets high performance requirements.
Structure and material characteristics
D-sub connectors are constructed and manufactured with durable and reliable construction and materials to ensure high performance even in harsh environments.
- Shell material: Steel or zinc die-cast shells are common, offering both corrosion resistance and strength.
- Contact material: Copper alloy contacts are plated with gold or silver to achieve wear resistance and high conductivity.
- Insulator: Made of polycarbonate or nylon material to ensure insulation and heat resistance.
D-Sub connector standard
D-Sub connectors comply with various industry standards and are widely compatible, making them easy to integrate into existing systems or new designs. Common standards include:
- MIL-DTL-24308: A US military standard that ensures reliability in defense and aerospace applications.
- DIN 41652: An international standard for industrial D-Sub connectors, based on German industrial standards.
- IEC 60807: An international standard by the International Electrotechnical Commission (IEC) that provides wide compatibility.

What is a single contact (signal)?
Signal contacts, defined for "low" currents of milliamperes up to 3 amps
What is HF contact?
HF contactor in its full name High Frequency contactor is a coaxial contactor that contains a central contact that conducts the signal (signal) isolated and above it a shell of shielding (Braid) K) for EMI/RFI protection.
What is the HP touch?
Contact HP or in its full name High Power, is intended for transferring currents of 3 amperes and up to 20 amperes, the interval between one HP contact and another will be 4 mm.
What is EMI?
Electromagnetic Interference
What is RFI?
Radio Frequency Interference
What is EMI/RFI protection?
While a current is passing through the contact or the cable, a magnetic field is created, the magnetic field that is created can interfere with the electrical data that you want to transmit, and in order to prevent this interference, the cable is wrapped in a shield, with the central conductor electrically isolated from the shield.
What is COAX contact?
A coax contact is intended in communications for transmitting signals at high frequencies, it contains a central contact that conducts the signal (signal) isolated and above it a shell of shielding (Braid) to prevent EMI/RFI interference. EMI - Electromagnetic Interference
RFI - Radio Frequency Interference
How do you choose a connector according to frequency (HZ) and impedance (Impedance-Ω)?
Nicomatic offers connectors for transmitting high frequencies from 1.5GHz to 11GHz depending on the cable. For the purpose of the characterization, it is necessary to define whether the frequency to be transmitted is up to 6GHz or beyond in order to choose the appropriate cable, in case you are not sure about the frequency, it is recommended to choose the appropriate cable for a higher frequency.
When to choose a plastic connector and when to choose a metal connector?
The choice of the connector material depends on the application, plastic connectors must be used for connectors inside the box and connectors that interface outside the box and need better protection from the electrically noisy environment, we will use metal connectors, in more extreme environments, we can add an additional layer of protection to the connector called BackShell (back accessory).
What is the advantage of SMT contacts (Surface Mount Technology) compared to intrusive contacts on the PCB?
In penetrating contacts (Thru-Hole), the connector is prevented from placing components on the other side of the PCB board, while in surface mounting the bottom side of the PCB is intended for independent editing and placing additional components.
Golden advice for designing connectors on a PCB board
Depending on the required task and especially the required mechanical size, it is advisable to use connectors that have a small pitch between the contacts, thus making it possible to design a compact and lightweight package, something that is very much required in optical systems and UAVs (unmanned aerial vehicles).
