SS250MKIV Absolute Encoder Positioner Upgrade

SIDUS SS250MKIV Upgrade: Precision Meets Performance

The SS250MKIV Upgrade from SIDUS is a transformative enhancement for users of the existing SS250 series! Part of the trusted SS250MKV family of Absolute Encoder Positioners, this upgrade delivers the full power and precision of SIUDS’s latest absolute encoder technology – at a significantly reduced cost – and removes the homing process for position feedback.  It’s designed to elevate operational performance in demanding environments where accuracy and reliability are non-negotiable. 

Engineered for critical tasks, such as positioning sensors, cameras, and payloads, the SS250MKIV inherits the proven dependability of the SS109 and SS250 series. Its modular assembly integrates reversible synchronous motors, extremely low backlash harmonic drives, and precision ball bearings, ensuring long-term durability and simplified maintenance.

Field-tested across global subsea operations, this workhorse excels in applications that require high-precision encoders for underwater robotics and scientific instrumentation. The 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.
