Electric Throttle Control Subsea Actuator Connector

The product range includes actuators rated to 3,000 msw (meters of sea water) for deep-water ROV and offshore operations, as well as models rated to 6,000 meters for ultra-deepwater deployments. All units are pressure-compensated with oil to ensure reliable performance at extreme depths.

The self-compensated linear and rotary actuators support RS422 (RS485 full duplex on 4 wires) and RS232 serial communication at 19200 baud, 8, N, 1. Communication parameters, virtual limit switches, and broadcast frequency (default 10 Hz) are configurable and stored in internal EEPROM for persistent settings.

Yes. The self-compensated actuator models feature an absolute 30-bit multi-turn encoder mounted directly on the output shaft. This encoder retains full positional information — including turn count — across power cycles, eliminating the need for re-homing routines after restart and ensuring consistent positioning in critical subsea operations.

High-force linear actuator models (rated to 6,000 m) are available in Stainless Steel 316 (SST 316) or Titanium, both offering superior corrosion resistance in marine and offshore environments. Self-compensated models feature housings engineered to contain integrated electronics and withstand subsea pressure at depths up to 3,000 msw.

The self-compensated linear and rotary actuators use an MCBH8M SubConn underwater connector (8-pin), with a 12" MCIL8F whip cable included on the linear model. High-force linear actuators rated to 6,000 m use a Seacon underwater connector, both of which are designed for reliable electrical connectivity in subsea environments.

These actuators serve deep-sea robotics, ROV manipulation and propulsion, subsea valve and pipeline actuation, offshore oil and gas equipment, marine research instrumentation, water tank cleaning robots, and oceanographic exploration systems. Models spanning 1,000 N to 77,500 N axial force accommodate both precision laboratory-scale and heavy-duty industrial underwater operations.
