R-10-FB Underwater Rotator

 

Single axis underwater rotator with position feedback and optional RS-485 control to remotely orient camera systems, acoustic equipment, and other instrumentation.

The unparalleled reliability of the R-10-FB underwater rotator is due in part to its rugged construction. Housings and machined components are made of corrosion resistant, hard-anodized aluminum. All external hardware is made of stainless steel for deep water or hazardous environment applications.

The R-10-FB provides 13.56 N-m (10 lb-ft) of
output torque. Heavy-duty ball bearings supporting the output shaft allow it to accommodate heavier payloads up to 25 pounds. The drive train for the rotator uses either a reversible synchronous motor
or a brushless stepper motor coupled to low
backlash harmonic gearing. The rugged design
of the gear train allows stalling of the output shaft without damage to the gear or the motor.

This positioner is equipped with an internal limit
switch and position feedback potentiometer. The potentiometer senses rotation orientation angles for display at the remote control station.

With the choice of different power configurations, AC or DC, the R-10-FB can be used in a wide array of varying environments and applications. Additionally, the 24 VDC model with optional RS-485 communication protocol is highly configurable and precision controllable.

All ROS positioning units are available in either
single or dual axis configurations.
