How do I obtain 3D CAD models?

Harwin have partnered with SamacSys, a leading supplier of 2D schematics, PCB footprints and 3D models, to bring you the resources you need for designing our components on your boards. Every product page features a link to the SamacSys library.

How to find the Model

On the product page, you will see a CAD Model button located in the top section, just under the introduction text and Samples/Availability buttons. When you click on this button, you will see two options of CAD models.

View the video at the bottom of this support article to see the process in action.

Harwin CAD Models

Harwin models require no registration. All CAD models are offered in STP format, which should import into most 3D CAD systems. You will need the appropriate software to view these models. Some products also have IGES formats available (not available on all models due to file size considerations). All model downloads are packaged into ZIP files to make your download smaller.

These 3D CAD models are complete models of the product itself, not the PCB layout configuration. If you are looking for PCB layout models instead, please use the SamacSys link.

If there are any issues with a Harwin-supplied CAD, please use the Contact form to talk to our Webmaster Team.

Accessing SamacSys files

The SamacSys download options include CAD models in a wider variety of formats, PCB footprints and circuit schematics. Depending on the existing availability of models, you will see one of a selection of buttons:

Clicking on this button will present another popup window (see image right). Some products have already been processed and have the layouts, models and schematics ready to download – others you may need to request using the SamacSys interface.

To download the required files, you will need to register with SamacSys. If you have already registered on their core site (ComponentSearchEngine.com), you can use the same login information here. Click on the “Download ECAD Models” to access the login box.

Once logged in, you can download the applicable files you require. For more information on the SamacSys file types and suitable CAD systems, please consult the SamacSys help pages:
