CMM family
Plastic rectangular connectors designed to meet and exceed the performance levels required by the MIL-DTL-55302F standard for electrical and mechanical performance.
。
There are five series in the CMM family.
CMM-100 series: This series is dedicated to signal contacts and consists of one row of contacts, containing from 2 to 25 contacts. In this series, the connection between male and female connectors is made with a spring latch.
CMM-200 series: This series is also dedicated to signal contacts and consists of two rows of contacts, containing from 4 to 50 contacts. In this series, the connection between male and female connectors is made with a spring latch.
CMM-220 series: Three contact types can be combined in this series: high frequency connector (HF), signal contact (LF), and high current contact (HP). The signal contacts are arranged in two rows, and when incorporating coaxial contacts or high-current contacts, they occupy the space of four signal contacts. In this series, the connection between male and female connectors is made with screws.
This connector allows you to combine flexible wiring, flat cable (FFC), etc. For more information on CrimpflexCrimpflex pagePlease take a look at
CMM-320 series: Three contact types can be combined in this series: coaxial (up to 6GHz), signal contacts (3-5 amps per contact), and high-current contacts (20-40 amps per contact). Connectors that combine different types of contacts can combine up to 40 signal contacts and 20 high current or high frequency contacts. The series consists of three rows of signal contacts. When incorporating coaxial contacts (high frequency) or high current contacts, these contacts occupy the space of four signal contacts. In this series, the connection between male and female connectors is made with screws.
CMM-340 series: This series is similar to the CMM-320 series, but here the coaxial contacts (high frequency) are up to 1.5GHz and the high current contacts are up to 10 Amps. Can be configured from 4 high current or high frequency contacts up to 64 contacts. In this series, the connection between male and female connectors is made with screws.

Question/Answer
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).
