Detailed description

El sensor d'angle de timó Raymarine amb cable de 10 metres (referència M81105) és un component essencial per optimitzar el rendiment del vostre sistema de pilot automàtic. Dissenyat per proporcionar una resposta precisa i en temps real sobre la posició exacta del timó, aquest sensor permet que el calculador de timó reaccioni amb més rapidesa i millori el manteniment del rumb, reduint així el desgast de la unitat de potència i el consum elèctric.

Precisió mecànica i integració en el sistema

A diferència dels sistemes virtuals d'angle de timó, la instal·lació d'un sensor físic com el model M81105 garanteix una fiabilitat absoluta, especialment a baixa velocitat o en condicions de mar formades. Subministrat amb un cable generós de 10 metres, és perfectament adequat per a velers i llanxes que requereixen una distància llarga de cablejat entre la mènsula del timó i el calculador del pilot (tipus ACU Raymarine). El seu pes de 0,7 kg evidencia una construcció robusta adaptada a les condicions de l'entorn marí.

Instal·lació i fiabilitat

Aquest sensor de posició de timó s'integra nativament en l'ecosistema Raymarine. La instal·lació mecànica requereix connectar el braç del sensor al sector del timó o a la mènsula, respectant l'alineació detallada en el manual d'instal·lació proporcionat. Un cop calibrat, transmet les dades a la xarxa, permetent també la visualització de l'angle de timó en els repetidors i pantalles multifunció, oferint una seguretat addicional durant les maniobres de port.

« The mechanical precision essential for a responsive autopilot »

Installing a physical rudder angle sensor remains the golden rule for any high-performance autopilot system. While modern algorithms sometimes allow bypassing this on small units, the Raymarine M81105 sensor delivers unmatched mechanical precision. It eliminates latency in the autopilot computer’s rudder position estimation, which is critical when running downwind or during delicate manoeuvres. The 10-meter cable included as standard is a genuine technical asset, preventing risky splices in the damp bilge when connecting to the onboard network.

Frequently Asked Questions

Need help? Contact us

What exactly is the Raymarine M81105 rudder angle sensor used for?

The Raymarine M81105 rudder angle sensor is a mechanical component that measures the exact position of your rudder. It sends this data in real time to your autopilot computer, enabling it to react faster and more accurately to maintain course.

What are the advantages of installing this sensor compared to a virtual system?

Installing a physical sensor like the M81105 offers several advantages:

Increased reliability: It provides real data rather than an estimate, which is critical at low speeds or in rough seas.Better performance: The autopilot responds more quickly, improving course-holding accuracy.Energy savings: By optimizing rudder corrections, it reduces wear on the power unit and electrical consumption.

With which Raymarine autopilot systems is this sensor compatible?

This rudder angle sensor is designed to integrate natively with Raymarine autopilot computers of the ACU (Actuator Control Unit) type. It connects directly to the dedicated port on these computers.

Is the installation of this sensor complicated?

Installation requires basic mechanical and electrical skills. It consists of two main steps:

Mechanical mounting of the sensor and its linkage to the tiller quadrant or rudder stock.Wiring the cable to the autopilot computer.Once installed, a calibration step via the autopilot interface is essential.

What is the length of the cable supplied with the sensor?

The M81105 rudder angle sensor comes with a 10-metre cable, which is suitable for most sailboats and powerboats.

Can I use this sensor with an autopilot from another brand?

No, this sensor is specifically designed for the Raymarine ecosystem. It is intended to be connected to the brand's processors and is not compatible with systems from other manufacturers.

Do I need to calibrate the sensor after installation?

Yes, calibration is a mandatory and essential step after installation. It allows the autopilot to learn the rudder stops (port and starboard) and the position of the mid-point to function correctly.

Will this sensor allow me to see the rudder angle on my displays?

Yes, once connected to the autopilot computer, the rudder angle data is transmitted over the network. You can then view the rudder angle in real time on your Raymarine multifunction displays and compatible repeaters.

What is included in the M81105 product box?

The box contains the rudder angle sensor itself, its linkage arm, and the attached 10-meter cable. The basic mounting hardware is also included.

Is this sensor suitable for a sailboat and a motorboat?

Yes, this sensor is perfectly suited for sailboats and motorboats equipped with a compatible Raymarine autopilot system. The 10-meter cable length provides great installation flexibility on different types of boats.

Where should the sensor be physically installed?

The sensor must be mounted near the steering system. Its arm must be mechanically connected to the rudder stock or the quadrant to accurately track its rotational movements.

Where does the sensor cable connect?

The 10-meter cable connects directly to the dedicated port for the rudder angle sensor ('Rudder') on your Raymarine autopilot computer (ACU type).

Can this sensor be connected directly to a Raymarine multifunction display?

No, the rudder angle sensor cannot be connected directly to a multifunction display. It must be connected to an autopilot computer (ACU), which processes and broadcasts the information on the network.
