DMM Micro-D Mix-Steckverbinder sind Leiterplatte zu Leiterplatte, Leiterplatte zu Draht, Draht zu Draht, und Vorder- oder Rückseite Steckverbinder. Sie sind komplett modular und hybrid. Alle Serien sind für Kabel- und gedruckte Leiterplatten-Anordnungen. Sie bieten im Vergleich zu traditionellen Micro-D MIL-DTL-83513G-Steckverbindern erhebliche Vorteile. DMMs sind mechanisch stark (Metall-Steckergehäuse - 6061 Typ-Legierung mit chemischen Ni 10 µm) und sind EMI/RFI 360° geschützt.

- Saves space: lower profile, high density package & small footprint

- Full modularity: choose signal, power or coax contacts

- easier maintenance: crimp contacts are removable

- Higher flexibility: options for front/rear panel mount, straight/90°, cable/pcb

- Shorter lead-time & lower MOD

Shell: Aluminum 6061 type alloy w/ chemical nickel plating 10µm

Insert: Special PPS ranked UL 94-V0

Jackscrew: passivated stainless steel 300 series

In French, Connecteur Micro-Millimetrique or micro-millimetric connector. Its is a 2mm pitch connector.

Board to board, board to wire and wire to wire, CMM connectors give the designer a wide choice of configurations in data transmissions (HF or LF) and high power supplies (HP). The connector is available in mixed layout or in all signal.

Yes. For the CMM100 & 200, an optional latch offers the security of interconnection. For the CMM220, 320/340 and CMM Multi-Mix, an internal locking system is available (jackscrew mechanism).

Nicomatic offers 4 product families : CMM100/200 series, CMM220 series, CMM320/340 series and CMM Multi-Mix series :

a.
CMM 100, simple row of contacts, signal (LF) only
CMM 200, double row of contacts, signal (LF) only

b.
CMM 220 : double row of contacts, this connector benefits from the option of a mixed layout, giving the designers a choice of high frequency, high power, fiber optic (upon request) and low frequency.

c.
CMM 320, three rows environment with up to 16 special contacts (up to 120 LF contacts).
CMM 340, three rows with up to 64 special contacts if no signal contact is used.

d.

CMM Multi-Mix, 2 or 3 rows with possibility to mix HF, HP and LF contacts of same type in one connector.

CMM 100, 02 to25
CMM 200, 04 to 50
CMM 220, 04 to 60 (15 contacts HP/HF max.)
CMM 320, 06 to 120 (20 contacts HP/HF max.)
CMM 340, 06 to 120 (64 contacts HP/HF max.)

The following termination styles are available : board solder, surface mount, crimped on cable or solder on cable and pressfit.

Yes, UL 94-V0 norm.

up to 30 A depending on cable and test routine used.

Up to 11 Ghz (depends on the cable used and test routine followed).

Yes. This is a 1 time reinsertion for LF crimp contacts, 50 cycles for special contacts HF/HP series 30 (Coaxmatic 30) and 5 cycles for special contacts HF/HP series 22 (Coaxmatic 22).

CMM321:
Contact area is copper alloy/ Ni (2µ) + Au 1µ
Contact tail is copper alloy / Ni (2µ) + Au flash 0.1µ
CMM322:
Body is copper Alloy / Ni 2 µ+ Au 0.2 µ
Socket boby is Beryllium Alloy / Ni 2 µ + Au 1.25 µ

Nickel 2µ is used as a barrier against migration of Au. If you put Au directly on copper that would lead to gold pollution and then to oxidation, so there will be a very bad contact resistance.

Minimum Breakdown Voltage = 1000 Vrms
Withstanding voltage = 750 Vrms
Rated Voltage = 250 Vrms (also called operating voltage)

With AMM, you can arrange 6, 10, 20, 34 and 50 signal contacts. Those pin counts are standard and stocked. It is possible to have other arrangements from 4 to 50 upon request, please contact us.

Standard pre-wired female connectors are delivered with mounted jackscrews (V16) and blue AWG28 MIL wire, backpotted. It is available in lengths of 150, 300 and 450mm.

Those versions are stocked.

You can also select other AWG (AWG26 or AWG30) with other wire colors and adapted length upon request.

It is a polyester carrier with pre-positioned domes. It can be described as a custom made array according to the specification of our customers.

The array will make it possible to place at once all the keys of your MMI switch. This you will avoid all problems related to dome positionning, lacking dome double or reverse dome.

The array with kiss cuts is an array with a series of cuts in the polyester/adhesive carrier around the dome. It is considered as a standard product. However, P.A.S. arrays tend also to become a standard. It depends on the usage.

P.A.S. (Pre-assembled spacer). It is an additional layer applied under the retaining layer with channels enabling a volume of air around the dome. The spacer can be made of different materials, for example with polyester 0.1mm thick or transparent PET 0.1mm thick.
The ventilation is made via channels in the spacer layer connecting the various dome chambers.

The data are the same, the only difference is the taping's quantities.

It is the same one.

Shelf life after opening the moisture proof packaging of LEDs has changed from 1 year to 1 week. It is recommended that customers use all LEDs within the package at one time.If the LED after unpacking is not used, it must be resealed and stored, and it is recommended to bake before the next use of the upper part.

It is a patent & trademark of Nicomatic. The Switch'Air dome helps to create a cushion of air between the domes so that they do not stick together. This process ensures an efficient and reliable automatic placement.

There are 2 types of dimple : dimple & micro-dimple. The micro-dimple exists for 6mm domes. Thanks to its small size it allows, in case of dust on the circuit, to eliminate the dust and make the contact.
The dimple on the 8.4mm,10mm & 12.2mm is recommanded for flexible circuits in order to limit the travel.
