Micro connectors with a pitch of 2.0 mm

CMM connectors

Micro connectors with a pitch of 2 mm between contacts.

The modularity of Nicomatic connectors allows over 20 million different configurations of connectors:

A connector with contacts signal only (3-5 amps) can contain from 2 contacts up to 120 contacts.

A connector containing only high current contacts 20-40 amps, can contain from 2 contacts to 15 contacts in the CMM220 series.

A connector containing only Coax contacts  Can contain from 2 contacts to 15 contacts in the CMM220 series.

The main advantages of CMM connectors:

  •  High modularity: low current contacts (signal - 3-5 amps, depending on the application)
                               High current contacts (20-40 amps, depending on the application)
                               COAX contacts, possibility of straight or angled contact for a variety of COAX cables
                               One row and up to 3 rows of contacts
                               From 4 to 120 contacts
  • Spacing between contacts 2 mm
  • Configurations: board-to-board, board-to-wire, wire-to-wire
  • Space saving up to 60%, weight saving up to 50% compared to other rectangular micro connectors with the same functions
  • Temperature range: 60°C- committee + 260°C
  • High resistance to vibrations and shocks
  • Immunity with PPS material: no moisture absorption, no oxygen, radiation resistance and also solvent resistance (known PPS properties for space applications)

CMM family

Rectangular plastic connectors, designed to meet the electrical and mechanical performance of the MIL-DTL-55302F standard and beyond the performance level required by this standard.

The CMM family contains five series:

CMM-100 series: This series is intended for signal contacts only, and consists of one row of contacts and contains from 2 to 25 contacts. In this series, the connection between a male connector and a female connector is made using a spring catch (Latch)

CMM-200 series: This series is intended for signal contacts only, and consists of two rows of contacts and contains from 4 to 50 contacts. In this series, the connection between a male connector and a female connector is made using a spring catch (Latch)

CMM-220 series: In this series you can combine three types of contacts: coax (HF), signal (LF) and high current (HP). The series contains two rows of signal contacts. If we decide to combine coax contacts, or HP, the contact will take the place of 4 signal contacts. In this series, the connection between a male connector and a female connector is made using screws.

Flexible wiring, FFC flat cable, type- Crimpflex.

CMM-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 of different types of contacts, up to 40 signal contacts and 20 HP or HF contacts can be characterized.

The series contains three rows of signal contacts. If we decide to combine coax contacts (HF), or HP, the contact will take the place of 4 signal contacts. In this series, the connection between a male connector and a female connector is made using screws.

CMM-340 series: This series is similar in its combinations to the CMM-320 series, except that the coax (HF) contacts are up to 1.5GHz and high current up to 10 amps, and can be characterized from 4 HP/hf contacts to 64 contacts. In this series, the connection between a male connector and a female connector is made using screws.

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).
