The Doppler sensor features a 21.1 mm aperture, is compatible with a 21 mm diameter, and has a thickness of 8.5 mm.

Since the original physical product is protected by a design patent, the uploaded 3D model has had the recessed texture removed.

The bottom is equipped with 10 holes that accommodate M12×12 blind plugs, which can be used for ballast to facilitate direct submersion testing without the need for a support structure.
