Ekinox Subsea – Hardware Manual EKINOXSUBSEAHM.1.4
3. Mechanical specifications
3.1. Overview
The Ekinox Subsea enclosure is composed of titanium parts, one for the cover and one for the base plate.
The device uses high quality alloys and connectors to offer a depth rating of 200 m or 6 000 m, and good
resistance to seawater environment.
Note: If you are planing to use Ekinox internal magnetometers, please make sure that you don't use
ferromagnetic materials to mount the device.

3.1.2. Device mechanical alignment
For best measurement accuracy, a good mechanical alignment is required. During manufacturing, the
Ekinox measurement frame has been carefully aligned to 0.02° with the base plate for roll, pitch and yaw
angles.
To ease the yaw alignment (X axis), the base plate features two alignment holes Ø 4 mm H8 that
guarantees with two taper pins Ø 4 mm h7 a yaw alignment better than ±0.04°.
