System overview
The SS309 rotates an inspection payload using a modular motor assembly and strain-wave gearing. Its anodized 6061-t6 aluminum housing is part of the documented SS309/SS310/SS320 family. Power, feedback, compensation and motion limits are configured for the application. A rotator is a single-axis component; the family sheet’s generic pan/tilt limit terminology does not imply a second axis.
Applications
- Rotating camera and sensor mounts
- Subsea inspection assemblies
- Remote payload orientation
Key features
- 14 ft·lbf DC or 10 ft·lbf AC torque configurations.
- 50 lb / 23 kg maximum payload.
- 12-bit position feedback and 0.5–20°/s output speed.
- Internal/external compensation options.
Technical details
Electrical and motion
- Supply
- 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; 650 mA analog DC. Additional source row says 350 mA at 24 VDC and requires clarification; 100 mA at 115 VAC.
- Maximum torque
- 14 ft·lbf at 24 VDC; 10 ft·lbf AC. Source lists 18/13 Nm; confirm non-equivalent converted values.
- Maximum payload
- 50 lb / 23 kg.
- Angular speed
- 0.5–20°/s.
- Position feedback
- 12-bit, approximately 0.1°.
- Backlash
- Source discrepancy: <36 arcminutes versus approximately 0.05°. Request confirmation.
- Optional limits
- Factory motion limits; source uses generic pan ±175° / tilt ±90° wording. Confirm the required single-axis travel.
Mechanical and environmental
- Housing
- Anodized 6061-T6 aluminum
- Dimensions
- Source lists Ø94 × 169 × 215 mm and Ø3.3 × 6.64 × 8.45 in; the diameter conversion and extra height require a model-specific drawing.
- Weight in air
- 2.1 kg
- Weight in water
- 1.3 kg
- Depth
- 3000 m with internal compensation; 6000 m with external compensation. The air-filled row names SS109HT, so it is not transferred as a rotator rating.
- Operating temperature
- −20 to +50°C.
- Storage temperature
- −30 to +60°C.
- O-rings
- Buna.
- Fasteners
- 316 stainless steel.
- Compensator
- Internal diaphragm, for oil-filled configuration.
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
Family document has conflicting dimensions and generic pan/tilt terminology. Confirm exact rotator drawing, limits and electrical configuration. No public current operating manual found.
Datasheets & documentation
