DMM - 2mm pitch metal connectors - MIL-DTL-83513G

DMM - 2mm pitch metal connectors - MIL-DTL-83513G

DMM rugged connectors comply with MIL-DTL-83513G performances and enable a wide choice of arrangements compared to other mil-spec connectors like Micro-d or Sub-d. They allow space-saving, electromagnetic & mechanical protection. Moreover, you can use one-piece or two-piece backshells for 360° shielding and protection of your cable interconnection. You can use DMM with Flange for better shielding continuity when mounting on a panel or without Flange as a low-profile solution.

Features :

  • 4 weeks lead time, MOQ = 1 part 
  • High modularity: contacts Signal ( LF),  Power (HP), and Coax (HF) up to 10M arrangements
  • Board to board, board to wire, wire to wire, panel mount (1 to 4 rows of contacts)
  • Miniaturisation: 2mm pitch, low profile
  • Ruggedized with aluminium alloy 6061
  • Easy maintenance thanks to dismountable contacts

Backshells for DMM series connectors

A backshell is the rear portion of a connector, which is normally a separate section from the connector head. It is used to secure the cable to the end of the connector in order to relieve strain on solder and crimp joints. It also shields against electrical interference (EMI/RFI protection), mechanical injury or physical damage due to environmental conditions.  Nicomatic Transfer Impedance is under 200mOhm from 10Khz to 400Mhz, which allows us to offer an excellent & clean data transfer from an emitting device to a receptor.

Assembly upgrade: molded insulator & back resin

Nicomatic connectors, especially the MIL-DTL-83513G DMM® connector range, have to be more and more compatible with high & harsh requirements. To reach this target and in a continuous spirit of improvement we have decided to upgrade our assembly process.

IP 68 & Sealing for Radar Application Case

The end user of the radar systems requires the system to be durable, reliable and with low maintenance.  In-order to track multiple targets, the system needs to have the most accurate information transmission and its protection of signal. The expectation of radar manufactures is very high, and that is why they demand excellent quality and performance from each component that makes up the entire system.

Higher ruggedness with DMM !

DMM series is a rugged, compact and shock resistant connector system. It is available in an all LF or mixed-layout configuration, with high frequency and/or high power contacts with possible arrangements of between 1 and 4 rows of contacts with up to 120 contacts.

DMM backshell, « The EMI fighter »

The multiplication of data in electronic systems could have disastrous results if the impact of the cross talk was not anticipated. Under an electromagnetic perturbation (EMI, RFI or EMP), the cable’s conductor acts as antennas and picks up the radiated signals. The reception of this interference surely impacts the initial signal integrity.

What is DMM?

DMM Micro D Mix Connectors Are A Board To Board, Board To Wire, Wire To Wire And Front Or Rear Panel Connector With A Fully Modular And Hybrid Range.

All Series Are Dedicated To Cable And Printed Circuit Board Applications. They Offer Many Advantages Vs. The Traditional Micro-D MIL-DTL-83513G Normalized Connectors.

DMMs Are Mechanically Strong (Metal Connector Shell - 6061 Type Alloy W/ Chemical Ni 10µm) And Are EMI/RFI 360° Protected.

Why use a DMM instead of a micro-d or sub-d connector?

- 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

What material is used for DMMs?

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

Insert: Special PPS ranked UL 94-V0

Jackscrew: passivated stainless steel 300 series
