Automatic Docking Connectors

D1 D3/D4 D12


With nearly 60 years of expertise in Mass InterConnects, VPC is extending its portfolio with interface designs optimized for product test environments. The compact design of the iDock Series and the lack of engaging mechanism, makes it ideal for high-volume product test changeover. The iDock Series is rated for 200,000 cycles.

Partially Loaded ITA

Partial Loading

Unlike many competitors, our frames can be reliably mated without every module being installed. In fact, the modules can be partially loaded and still function optimally. Using locator bosses, our modules' position tolerance is controlled in the receiver and ITA frame to ensure proper alignment without the excessive use of guide pins.

Design for the future; fill it when you need it.


While the load and force required will depend on the amount and type of I/O populated in the system, the interface design is based on the G12 design, a system that has been fielded and tested for more than 30 years.

Contact a VPC Field Application Engineer to determine the mating force required.

PCB Options

The iDock Series uses two standard VPC modules, which accept PCB solutions. The larger interface frames use high-density 90 Series modules, while our smaller frames use iCon modules. Both module types accept PCB options that can increase signal integrity and optimize cable management.

Floating Bushings

In an automated test setting, misalignment can lead to catastrophic failure. VPC docking frames are equipped with floating bushings to provide up to .040" [1.016 mm] of radial float to compensate for alignment. The floating bushings preserve the frames and contacts during each mating cycle.

Hybrid I/O Options

The iDock Series frames accept modules of different I/O types. Whether testing with power, signal, RF, data, fiber, or vacuum, these modules can be inserted side-by-side. Furthermore, many VPC modules are hybrid in nature, meaning that these I/O requirements can be intermixed in the same module, lending further flexibility and diversity.

Configure Your Solution

Continue to our technical section review part numbers for the receivers and ITAs, accessories, and a variety of preconfigured modules compatible with iDock Series connectors. Check back periodically as we continue to add new configurations.

As always, if you do not see the configuration you require, please contact your local Field Application Engineer to see if we can accommodate.
