True Axis SS250MKV Absolute Encoder Positioner

SIDUS’s True Axis SS250MKV Absolute Encoder

The True Axis SS250MKV family of Absolute Encoder Positioners are engineered to deliver pinpoint accuracy for critical tasks such as aligning sensors, cameras, and heavy payloads.  Its modular assembly integrates reversible synchronous motors, extremely low backlash harmonic drives, and precision ball bearings, ensuring long-term durability and simplified maintenance.

With continuous 360° rotation, no homing routines, and instant absolute position recognition upon power-up, these devices redefine operational efficiency. The integrated braking system and high-resolution feedback ensure maximum productivity and safety. The True Axis SS250MKV knows where it is at all times, at startup or after losing power, eliminating homing routines, while retaining all the great features of the SS250MKs that the industry has come to rely upon, with improved reliability and confidence.

Designed for seamless integration with both new and legacy systems, the True Axis SS250MKV series offers enhanced interfacing capabilities with other OEM platforms. Its modular, field-serviceable architecture and inductance-based incremental encoder technology make it a versatile solution for high-load remote positioning applications. It’s designed to elevate operational performance in demanding environments where accuracy and reliability are non-negotiable. 

Field-tested across global subsea operations, this positioner workhorse excels in applications that require high-precision encoders for underwater robotics and scientific instrumentation. Our new absolute encoder positioner features enhance efficiency, redundancy, and real-time positional precision.

Key performance highlights include:

• Torque ratings up to 65 ft-lbs, securely housed in a corrosion-resistant, one-piece underwater enclosure.
• Modular design enables field repairs using only small tools – ideal for offshore deployments.
• Depth rating of up to 10,000 ft / 3000 m with internal compensation
• Depth Rating of up to 20,000 ft / 6000 m with external compensation
• Continuous 360° rotation with instant absolute position recognition at power-up, no homing routines required
• Drive command options include analog control and serial interfaces: RS232, or RS485, offering flexible integration across platforms.
