Motion Sensor Cables

SMC Surface marine motion sensors are delivered with a 10 meter TPU, shielded 19 core cable, suitable for marine installations.
The submersible versions of motion sensors are delivered with a 10 meter Seacon 12 core cable. When the motion sensor is delivered the cable and junction box are included in a bundle package ready to be used.

As an option cables are available in the lengths of 5, 10, 20 and 30 meter for the surface type of motion sensor and 10 and 30 meters for the submersible motion sensor.


Transit case

A protective transit case is included in the delivery of all SMC motion sensors. Due to the sensitive nature of the motion sensor the transit case can be used to give additional protection during transportation for service or other relocation of the motion sensor on board the vessel.

The transit case is waterproof, IP67 rated, resistant to chemicals, humidity and dust.

Junction box

The SMC motion sensor is supplied with a junction box on delivery with no additional cost.

The motion sensor junction box is provided complete with terminals and power supply for 110-220 VAC. Serial communication cable, power cord (EU or US) and the motion sensor communication cable are provided ready fitted to the junction box. The enclosure size for the motion sensor junction box is L160 x W160 x H90 mm.

The box has an ingress protection IP66 in accordance with EN 60529.

The material used for the junction box can be selected between:

GRP
Glass Reinforced Polyester, for improved corrosion resistance.

Aluminium
For better grounding abilities.

Wall Mounting Bracket

An optional mounting bracket is available, designed to simplify wall mounting installations combined with easy motion sensor alignment. One advantage with the mounting bracket is that the motion sensor can be removed for servicing or recalibration and repositioned in exactly the same position.

The bracket base plate has two pins that correspond to two of the notches in the Motion sensor base. Alignment adjustments can then be made by rotating the bracket adapter.

The mounting bracket is delivered with a mounting adapter and screws for fixating the motion sensor to the bracket. The mounting bracket is produced in Stainless steel 316.

The base plate adapter can also be purchased as a separate item from the wall mounting bracket.

Enclosure for motion sensor

To extend the motion sensor lifetime SMC recommend using a protective enclosure during offshore installations. The optional enclosure provides additional protection to the motion sensor when required.

The protective enclosure for the SMC motion sensors is produced in a corrosive resistant Marine Grade AISI 316L Stainless Steel material. The enclosure is delivered including a terminal list, cable glands mounted in a cable entry flange and a mounting bracket with an adapter for the SMC motion sensor range IMU-00x and IMU-10x.

The enclosure size is L500 x H400 x W250mm and has an IP66 rating for water and dust and IK10 for impact force. The enclosure has a weight of 17 kg including the mounting bracket and terminal list but excluding the motion sensor weight.

316L Enclosure datasheet

As a cost effective alternative to the AISI 316L motion sensor enclosure a Glass Reinforced Polyester (GRP) protective enclosure is IP66 rated. The enclosure is fitted with a terminal list inside of the box, cable glands and a mounting bracket for the motion sensor.

The enclosure size is L600 x H400 x W230 mm and is IP66 rated.

Hazardous area enclosure Ex D

SMC offers an Ex D enclosure option for the motion sensor for installations in Hazardous Areas. The material used for the Ex D enclosure is corrosion and saltwater resistant aluminium covered with polyurethane paint and IP65 rated.

The motion sensor is mounted in the Ex D enclosure by certified personnel before delivery and is connected to terminals.

The dimensions of the Ex D motion sensor enclosure is: L535 x W468 x H257 mm.

Analog output

The Analog output junction box replaces the included marine motion sensor junction box. There are 4 available analog output signals which can be set for +/-10 V, 0-20 mA and 4-20 mA. The outputs are predefined from a user selection in the motion sensor output protocols.

The enclosure material is GRP and the size for the analog output junction box is L360 x W160 x H90 mm.
