MIL-DTL-83513
MIL-DTL-83513 is a U.S. military standard that establishes design and performance requirements for microminiature D-sub connectors (commonly known as "micro-D connectors"). This standard was created to ensure the quality of small connectors used in harsh environments, especially those used in military, aerospace, and other systems that require high reliability.
Background and purpose
MIL-DTL-83513 was developed by the U.S. Department of Defense to unify the design and performance requirements for micro-D connectors used in military and aerospace applications where reliability is critical. This standard provides a basis for reliable signal transmission and power delivery in systems where miniaturized connectors are used.
Main features of MIL-DTL-83513
MIL-DTL-83513 is a standard for micro-D connectors primarily suited for applications requiring small, high-density connections. This connector is even smaller than a regular D-sub connector, yet offers the same reliability.
- Miniaturization and high density: MIL-DTL-83513 compliant connectors are extremely compact and can accommodate many contacts in a limited space, making them ideal for equipment and systems with limited size.
- Reliability: Designed to perform reliably under high vibration, shock and harsh environmental conditions.
- Different number of contacts: The number of connector contacts ranges from 9 to 100, allowing flexibility in selection depending on application requirements.
Testing and performance
MIL-DTL-83513 compliant connectors undergo rigorous testing to ensure durability and reliability, including:
- Vibration and shock: Connectors are tested to ensure the connection remains intact when subjected to vibration and shock. This is suitable for environments with harsh vibrations, such as aircraft, spacecraft, and tanks.
- temperature: It will be tested to work in extreme environments of high and low temperatures to ensure its suitability for use in space and high altitudes.
- Moisture resistance and corrosion resistance: It is required to be able to be used for long periods of time even in humid or corrosive environments.
- Durability: It is guaranteed that the contact performance will not deteriorate even after numerous connection and disconnection cycles.
Material and structure
MIL-DTL-83513 compliant connectors are made from specially designed materials to maintain performance under harsh conditions.
- Electrical contacts: Copper alloy or gold-plated contacts are usually used to ensure good conductivity and corrosion resistance.
- Exterior: Light and durable aluminum alloys and stainless steel are often used to provide both light weight and strength for space and aerospace applications.
Typical use
Micro-D connectors that comply with the MIL-DTL-83513 standard are widely used in applications such as:
- Aerospace: The compact and lightweight design makes it ideal for space equipment and aircraft electronic systems. These environments require them to withstand high vibrations and extreme temperature fluctuations.
- Military vehicles and weapon systems: Communication and control systems used in military vehicles such as tanks and armored vehicles require reliable connectivity under harsh environmental conditions.
- Medical equipment: They are also used in medical equipment where miniaturization and high reliability are required, and provide secure connections even in sensitive electronic equipment.
Standard updates and versions
MIL-DTL-83513 is revised regularly in response to evolving technology and the needs of the military and aerospace industries. Checking the latest version is important to ensure that your products always comply with the latest requirements.
Certification and compliance
To deliver products that comply with MIL-DTL-83513, the manufacturing process must pass rigorous standard-based testing. This ensures that the connector offers high reliability and durability even in harsh environments.

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).
