D-sub Connector: solutions in various standards, forms & configurations

The D-sub connector is very versatile, from multiple Data Signal transfers in Serial communications such as in RS232 and RS485,  Contacts are arranged with up to 78Pins, delivering Power up to 40A and Radio Frequency communication in combo types. The D-sub is also very robust, intended to be used in high Vibration and Shock,  Noise or EMI that affects transmission quality and Harsh environment that requires Waterproof Protection.

AUK is a D-SUB Connector manufacturer and supplier founded in Taiwan for nearly 40 years, providing high-quality products, and as one of competitive D-SUB Connector suppliers worldwide as well as OEM ODM precision manufacturing services.

AUK's D-sub connector solutions accommodating Mechanical, Electrical, Environmental and other special requirements to achieve product completion. Solutions related to Low Profile, Ganged type arrangements for Multiple port applications and various Height using specific Stand-off or Pin lengths are offered along with other solutions such as Boardlocks and insulated Plastic back shells. AUK never stopped providing support the development of the D-sub connector which can be observed with our broad range of items and solutions available.

  • Slim Solution

    Slim type versions that can fit into dense modules with dimensions as thin as 10.0mm total connector length and footprint either with 1.2mm (DR12), 2.5mm (DR25) or 5.0mm (DR50) distance from the PCB edge, while Straddle type is also available where the connector can be mounted at the PCB edge.
  • High Fidelity Filtered Signal

    D-sub are equipped with Filters that helps suppress Noise and other electrical disturbances such as EMI and RFI, this prevent interferences in critical applications like in navigation or communications systems that can result to potentially devastating effects.
  • Various Termination style Available

    Equipped with Insulation Displacement Connection (IDC) termination option. Typical Crimp type is also available, while Press Fit helps to secure high contact force into PCB througholes and all other standard termination such as DIP and SMT that is commonly used.
  • Superior Reliability Machined Pins

    The solid structure of Machined Pins basically delivers strength and durability to the connector particularly significant in mating and during termination either through cable assembly or along high temperature soldering processes.
  • Combo D-sub Power/ Coaxial

    Hybrid options with Power or Coaxial contacts is commonly called a Combo D-sub. This can deliver both Power ranging from 10A~40A, and Data available in 9~78 pins or with RF with 50Ω or 75Ω impedance.
  • IPX7 Rating Waterproof Protection

    Waterproof D-sub rated to IPX7 is available with carefully designed sealing by using O-ring, Potting and also using water resistant materials to ensure reliable performance.
