LED Lamps

Our advanced, compact LED lamps are designed to complement our successful robotic vehicles.

Made from 6082 grade aluminium, the lights are designed and manufactured to operate in the toughest conditions. With low power consumption (34 - 40 W), light weight, high brightness (3520 lumens) and a long life, these lights are ideal for the subsea environment. With a depth rating of 3,000 msw, these lights are made to fit a variety of vehicles and are compatible with existing Saab Seaeye vehicles in the field.

Pan and Tilt Units

The compact and robust Pan and Tilt Units (PT35N and PT35N-C2) are designed for the harsh subsea environment.

Ideal for ROV camera / light platforms and multi-beam sonars, the units are rated to 3,000m. The side entry lid provides easy access for maintenance and inspection. The Pan and Tilt incorporates common units for both the pan and tilt functions, making the units easier for maintenance and fault finding. 24 VDC brushless motors drive harmonic gear modules to provide a high output torque, combined with precise control and positional feedback in a compact design. Control is via RS485 (PT35N) or Castle 2 Protocol (PT35N-C2). The housing is oil filled with an integral compensator and includes a low oil level alarm.

Metal Shell Connectors

Our comprehensive range of connectors and cable whips are specially designed for prolonged use in deep ocean environments to 5,000 metres and more.

Our connector receptacle shells, plug and mounting threads are made of high strength stainless steel and are corrosion resistant to salt spray, sea water, sand, mud, mineralised or demineralised water and hydrocarbons etc.

Watertightness and depth pressure rating have been given high priority during the design of the connectors and cable whips.
