DMM connectors

Metallic connectors with a pitch of 2.0 mm

DMM connectors

authors Metallic with a pitch of 2.0 mm.

DMM connectors are durable and conform to MIL-DTL-83513G standard performance. These connectors allow a large space of contact arrangements, thus they save space, and being metallic, they provide electromagnetic protection and mechanical protection - EMI/RFI.

A rear accessory (backshell) consisting of two parts (Split BackShell) or one unit (Mono BackShell) can be added to the connector for 360 degree protection for the chain connections.

In this series there is a large variety of standard fixings.

The main advantages of DMM connectors:

  • Compliance with the performance of the DTL-83513-G standard
  • A low-profile, vibration-resistant connector that provides 360-degree EMI-RFI protection
  • Compact connector
  • One row to four rows of contacts
  • Different types of contacts can be combined together (HP/HF/LF)
  • Maximum 120 high current contacts (3-5 amps) or 30 HP contacts (at a voltage of 20-40 amps)
  • A variety of contacts: push-wire*, perpendicular contact to PCB, angled contact to PCB, Thru-Hole and SMT contacts

* Wires - from 22 to 32 AWG, in signal contacts wires from 12 to 20 AWG, in power contacts and coax (HF) as RG tools (MKT 316, 179, 178, 174 and smaller)

The DMM family

DMM-100 series: The series contains a series of signal contacts starting from two contacts up to 30.

Types of contacts - wired, angled and straight to PCB including Thru-Hole and SMT.

DMM-220 series: Three types of contacts can be combined in this series: coax (HF), signal (LF) and high current (HP). The series contains two rows of signal contacts. If we decide to combine COAX or HP contacts, the contact will take the place of 4 signal contacts.

Types of contacts - crimped, angled and straight to PCB including Thru-Hole and SMT.

DMM-320 series: Three types of contacts can be combined in this series: coax (up to 6 GHz), signal (3-5 amps per contact) and high current (20-40 amps per contact).

In a combined connector with different types of contacts, up to 40 signal contacts and 15 HP or HF contacts can be characterized.

In a connector containing only signal contacts, you can get an arrangement of contacts from 6 to 90, arranged in three rows. If we decide to combine coax contacts, or HP, the contact will take the place of 4 signal contacts.

DMM-420 series: This series consists of four lines of signal contacts ranging from 8 to 120 contacts. Three types of contacts can be combined: coax (up to 6 GHz), signal (3-5 amps per contact) and high current (20-40 amps per contact).

In the connector that contains only signal contacts, you can get an arrangement of contacts from 6 to 90, arranged in three rows.

In a combined connector of different contact types, it is possible to specify from 2 to 30 COAX/HP contacts (pair arrangement only) if we decide to combine coax and/or HP contacts, the contact will take the place of 4 signal contacts.

DMM-430 series: This series consists of four lines of signal contacts ranging from 8 to 120 contacts. Three types of contacts can be combined: coax (up to 6 GHz), signal (3-5 amps per contact) and high current (20-40 amps per contact).

In the connector that contains only signal contacts, you can get an arrangement of contacts from 6 to 90, arranged in three rows.

In a combined connector of different types of contacts, it is possible to characterize up to 1 to 40 COAX/HP contacts (even/odd arrangement) if we decide to combine coax contacts, and/or HP the contact will take the place of 4 signal contacts.

Questions / Answers

What types of power connectors does Nicomatic offer?

Nicomatic offers a wide variety of power connectors, including high-density connectors between the contacts that are resistant to harsh environmental conditions.

How to choose the Power connector for my application?

The choice of a power connector depends on several parameters, including electric current, voltage, the number of contacts and the work environment, the type of application and more. We recommend talking to our experts for professional advice.

What standards do the Nicomatic power connectors meet?

Our power connectors comply with leading international standards such as ISO 9001, and MIL, DTL and RoHS standards - work standard series. To obtain the certification, you can contact us or download from the website.

What is the average shelf life of a Nicomatic power connector?

The lifespan of our power connectors depends on the type of connector and the conditions of use. But most connectors are made to withstand thousands of plugging and unplugging cycles. We would be happy to discuss further details and provide recommendations based on your application.

Can you customize power connectors for certain needs?

Yes, Nicomatic are experts in customization, according to the customer's needs, it is possible to use different materials, different assemblies and create connectors that will be adjusted and meet your unique requirements. Please contact our team to discuss your needs and receive a quote.

What are the normal delivery times for your power connectors?

Our delivery times depend on several parameters, including the type of connector, the order quantity and the available stock. For standard items, the delivery times will be about four weeks, in urgent cases you can get fast deliveries.

How can I get a quote for a large quantity of power connectors?

To receive a quote, please contact us through our website or contact our team directly and we will be happy to provide an offer according to your requirements.

What payment methods are accepted for purchasing power connectors?

You can pay by bank transfer or credit cards. Please contact us for more information on payment options.

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).
