Mehaaniline lineaarkäivitus 2. tüüp lühike, 300 mm, 24V

This Raymarine actuator (reference M81133) is designed for sailboats and motorboats requiring high thrust force for their steering system.

The standard Type 2 model has a 300 mm stroke, allowing it to maintain a compact installation format while delivering high mechanical performance.

This linear mechanical actuator operates exclusively with a 24V voltage.

It integrates seamlessly with Raymarine autopilot computers, including the ACU or SPX series, to ensure fast and highly accurate rudder response.

Installation requires precise alignment. The pushrod must be strictly perpendicular to the tiller arm when the rudder is in the central position. The allowed alignment variation is less than 5 degrees.

This mechanical ram acts directly on the tiller quadrant or the rudder arm of your boat.

The actuator alone weighs 7.72 kg. Due to this weight and the thrust force exerted, it must be mounted on a very solid structural base.

Raymarine recommends a full service by an authorized dealer every 1000 hours of use or every 2 years, whichever comes first.

For a 24V installation with cable length up to 3 meters, a 4 mm² (12 AWG) cross-section is required to avoid voltage drops.

If the power cable length reaches 5 meters, the manufacturer's specifications require the use of a 6 mm² (10 AWG) cable.

For a distance up to 10 meters at 24V, you must use cables with a 10 mm² (8 AWG) cross-section.

To avoid electromagnetic interference, the actuator must be installed at least 1 meter (3 feet) away from any equipment or cables transmitting radio signals, such as a VHF.

Yes, for HF radios (SSB), the minimum separation distance from the hydraulic ram must be increased to 2 meters (7 feet).

No, it is strongly recommended to power the equipment from a dedicated battery. Voltage drops during engine start (below 10V) could cause the autopilot system to reset.

No, reference M81133 is specifically designed for 24V systems. If you have a 12V network, you will need to choose the corresponding ram reference (M81131).

The actuator must be installed more than 2 metres (7 feet) from the radar beam path to avoid any electromagnetic interference.

Unlike type 1 models, the type 2 actuator offers superior robustness and greater thrust force, making it suitable for heavier and more demanding steering systems.

Yes, the industrial design of this hydraulic ram generates very high thrust forces. It therefore requires mounting on a structure capable of absorbing heavy loads. If in doubt, consult the manufacturer of your steering system.

Cutting or splicing cables specified by Raymarine is discouraged, as it may compromise electromagnetic compatibility (EMC) performance, unless the procedure is explicitly detailed in the installation manual.

For a very distant installation, up to 16 meters at 24V, it is imperative to use a heavy-gauge cable, specifically 16 mm² (6 AWG), to ensure stable power supply to the actuator.
