System overview
The SS109HT uses reversible synchronous motors and strain-wave gearing to orient a subsea payload. The November 2025 family datasheet distinguishes aluminum, stainless-steel and titanium housings and the selected power interface. Internal or external compensation determines the depth configuration. Modular motor assemblies support service and integration into inspection equipment.
Applications
- Camera positioning
- Sensor orientation
- Subsea inspection systems
Key features
- Two-axis motion with 12-bit position feedback.
- Up to 20°/s angular speed.
- Modular motor assembly and low-backlash strain-wave gearing.
- Analog or RS232/RS485 control configurations.
Technical details
Electrical and motion – November 2025
- Supply options
- 24 VDC, 24 VAC or 115 VAC.
- Maximum drive current
- 100–900 mA serial DC, speed dependent; 250 mA analog DC; 750 mA at 24 VAC; 150 mA at 115 VAC.
- Maximum static current
- 100 mA–1.2 A serial DC, selectable; 650 mA analog DC. The source additionally labels 350 mA as 24 VDC and 100 mA as 115 VAC; confirm the AC/DC configuration before sizing.
- Maximum torque
- 14 ft·lbf per axis at 24 VDC; 10 ft·lbf at 24/115 VAC. Printed 18/13 Nm equivalents are not exact conversions; confirm rated torque.
- Maximum payload

- Angular speed
- 0.5–20°/s.
- Position feedback
- 12-bit, approximately 0.1°.
- Scan range
- 360° both axes; 180° tilt with yoke.
- Backlash discrepancy
- Source prints <36 arcminutes and approximately 0.05°. These are not equivalent; manufacturer confirmation required.

Control and integration
- Serial control
- RS485 or RS232.
- Control software
- Laptop/PC with SIDUS Control Panel GUI, or a host implementing SIDUS serial commands.
- Analog control
- Analog control with feedback; factory configuration.
- Optional controls
- Pelco-D integration, keyboard/mouse/joystick control and digital feedback are listed as options.
- Connector
- Customer selectable; Subconn standard.
- Connector wiring
- Follow the connector diagram matching the ordered electrical interface; pin assignments are configuration-dependent.
Configuration options
Power and drive interfaceFactory configuration
Select the documented supply and analog or serial interface. Analog, AC and DC options have different current and torque ratings.
Mounting and motion limitsIntegration option
Agree mounting, payload centre of gravity, cable routing and required hard stops. Continuous rotation does not imply unlimited cable rotation.
CompensationDepth configuration
Internal compensation supports the stated standard depth. External compensation is a separate configuration; confirm fill fluid and all connected equipment.
Compatibility and naming
Backlash units and one static-current row conflict within the November 2025 family sheet. Older individual sheets contain different dimensions, supplies and depth conversions; current family values are kept separate. No public model-specific operating manual found.
