Stainless steel swivel for rudder angle sensor

The Raymarine D250 stainless steel universal joint is a stainless-steel mechanical component specifically designed for Raymarine rudder-angle sensors. It is an integral part of the linkage system between the rudder position sensor and the rudder stock or tiller.

The primary role of the D250 ball joint is to provide a flexible and robust connection, allowing smooth and unconstrained movement of the rudder angle sensor. This ensures that the helm position data is transmitted accurately to the autopilot, thereby contributing to precise course-keeping.

The Raymarine D250 ball joint is made of stainless steel. This material provides excellent resistance to corrosion and marine elements, making it perfectly suited for the nautical environment.

Each Raymarine M81105 rudder angle sensor uses two D250 ball joints for installation, as shown in the mounting instructions.

Yes, the D250 swivel is an original Raymarine component. It is designed to maintain the integrity and functionality of the brand's rudder angle sensing systems.

Yes, absolutely. Thanks to its stainless steel construction, the D250 universal joint is designed to be highly resistant to corrosion and harsh marine environments.

Its primary role is to provide a solid yet flexible mechanical connection, ensuring that the rudder movements are accurately and precisely transmitted to the rudder angle sensor, which in turn sends this data to the autopilot.

The D250 ball joint is specifically designed to be used with the Raymarine M81105 tiller angle sensor.

The D250 ball joint is an original Raymarine component designed for the M81105 sensor. Compatibility with rudder angle sensors from other brands is not guaranteed and is not recommended to ensure system performance and reliability.

The D250 ball joint is compatible with Raymarine autopilot systems that use the M81105 rudder angle sensor for rudder position detection. It is recommended to verify compatibility of your system with the M81105 sensor.

The D250 ball joint is a component that integrates into the installation of the M81105 rudder angle sensor. Installing the sensor itself requires following the specific instructions provided in the sensor’s installation guide.

The ball joint itself is an assembly component. Installing the complete M81105 sensor assembly, which includes the ball joint, may require the following tools:

A 3 mm (1/8 inch) drillA Pozidriv screwdriverA hacksawA pencilA measuring tape

The D250 ball joint is attached to the ends of the M81105 rudder angle sensor rod. The sensor itself is installed on the boat to measure the rudder movement, typically between the rudder stock or tiller and a fixed point.

Assembly instructions for the D250 ball joint are detailed in the Raymarine M81105 rudder angle sensor installation guide. This document explains how to assemble the sensor and its components, including the ball joints.

To ensure accurate measurement, it is crucial to strictly follow the M81105 sensor installation instructions. This includes ensuring the rudder is centered (amidships) and that the sensor is mounted parallel to the boat's centerline, with both ball joints properly secured and allowing unrestricted movement.

Yes, the M81105 sensor installation guide states that two ball joints (Ball joint x2) are included with the sensor at purchase. The D250 ball joint is also available separately as a spare part or for additional installations.

The D250 ball joint can be used in both cases: as a replacement part to replace a worn or damaged ball joint on an existing sensor, and as a component for a new installation of the M81105 rudder angle sensor.

Using a stainless steel swivel offers several advantages in a marine environment:

Corrosion resistance: Stainless steel withstands exposure to saltwater and moisture without degrading.Durability: It provides excellent resistance to wear and mechanical stress, ensuring a long service life.Reliability: Its robustness ensures a stable and precise connection, essential for autopilot performance.

Yes, the gimbal design is specifically engineered to allow smooth and flexible movement of the rudder angle sensor. This flexibility is critical for the sensor to accurately track the helm's movements without imposing mechanical stress.

Yes, it is very important to center the rudder (position "amidships") before starting the installation of the M81105 rudder angle sensor and its D250 ball joints. This step is essential to properly calibrate the sensor and ensure the accuracy of rudder angle measurements afterward.
