Marine Motion Sensor

The IMU-10x range of motion sensors refer to the products:
- IMU-106, heave
- IMU-107, roll / pitch
- IMU-108, roll / pitch / heave
- IMU-108-30, submersible roll / pitch / heave

The marine motion sensor IMU-10x series has been designed for multiple applications within the marine industry. Robust, versatile and accurate the IMU-10x motion sensor has an IP66 or IP68 titanium casing with high performance Micro Electro Mechanical System (MEMS) rate gyros and linear accelerometers which are processed by advanced algorithms producing a sensor for use in all dynamic environments.

Development over 10 years has produced a Motion Sensor suitable for applications from Active Heave Crane systems, Dynamic Positioning systems, Helideck Monitoring and other various Roll, Pitch and Heave motion applications.


Using a standard product design throughout the motion sensor range and with a product height of only 15 cm and width of 13 cm the SMC IMU-10x range is compact compared to equivalent products available today.

Design principle

SMC’s product development and design philosophy is to produce technologically advanced, durable yet uncomplicated products. Our aim is to reduce the cost of purchase and maintenance by reducing options and add-ons often associated with ancillary products. By doing this SMC does not require that a client invests in extra equipment they already have installed on a vessel.

Titanium Material

The casing material used in all of our IMU-series is Titanium. The most useful properties of Titanium are its high strength, low density and corrosion resistance in the Marine environments the motion sensor works in.

Mounting plate

The IMU-10x has the mounting plate as a part of the casing, no additional mounting brackets are required for a standard installation.

In the design of the IMU-10x, SMC has reduced the accessory add-ons by incorporating the mounting plate in the base design reducing the standard purchase costs.

Subsea Marine Motion Sensor IP68

For the submersible motion sensor IMU-108-30 depth rated for 30meter or optional 1000m, SMC has selected the IP68 classified Seacon Wet Mate Connector.

The IP68 standards classify the level of protection provided against the intrusion of dust and water.

Marine Motion Sensor IP66

For the standard surface marine motion sensor SMC selected the durable and easily sourced Amphenol Amphe-Lite 38999, series III, IP66 rated Mil spec composite connector. By selecting a readily available standard connection, clients have the security of long term supply and the ability to source cables and connectors from SMC or other suppliers.
