Designed by Exail, the 5E arm is a lightweight electrical arm used for underwater inspection and maintenance tasks. It offers a modular design and a low-power consumption, and therefore represents an optimum compromises between performance and weight.

Depth rated to 6000m, the oil filled 5E arm is used to conduct precise and articulated manipulation works. It can operate in confined and out of reach areas.

Brushless DC motors, ease of maintenance, wide range of jaws to be fitted on, large reach and high lifting capacity are among the most appreciable features of the 5E arm

This arm can be installed on any type of ROVs, and can be fitted with many kinds of grabbers : standard, bucket, with parallel jaws.
