Rudder Position Sensor - M81105 - Hello Below - 01-17-17 09:30 PM
In my attempts to gather information to assist me in installing my new M81105 on my sailboat, I came across this link:
http://raymarine.ning.com/forum/topics/rudder-reference-sensor-m81105
I appreciate that this forum is now longer active; however, the information that it contains is germane to my project. The dilemma I have pertains to the maximum angle that the Rudder Position Sensor can physically rotate. From the link, it seems, at least for this gentleman's application (EV-100), the maximum is 30° in each direction or a total of 60°.
On the instruction sheet that accompanied my sensor it shows the "Maximum permitted travel +/-60°". I take this as +/-60° from center or a total of 120° stop to stop. My rudder quadrant rotates approximately 90° from stop to stop. Please confirm that the Rudder Position Sensor can rotate greater than the 90° needed by the quadrant?
I will be electrically interfacing the M81105 to a SPX-5 Course Computer.
Thanks

Welcome to the Raymarine Forum Hello Below,
Raymarine's M81105 Rotary Rudder Reference Transducer does indeed support approximately 120 degrees of rotation. However, a properly installed Raymarine autopilot linear drive will limit rudder movement to +/- 30 degrees. Similarly, Raymarine's autopilots will not drive a rudder more than approximately +/- 30 degrees when operating in Auto or Standby modes. Additionally, should
- an Evolution or SPX autopilot be installed onboard, and
- a drive unit other than a linear drive be installed, and
- the rudder be moved more than approximately +/- 50 degrees,
then the autopilot will no longer report rudder angle, requiring that the autopilot be restarted (i.e. switched OFF and then switched ON again) to resume correctly reporting rudder angle.

Your information defines the physical limits of the Rudder Reference Transducer Arm. This is very useful. Thank you very much for that.
There (hopefully) should never be a time when it would be necessary for the autopilot to drive my rudder greater than +/- 30° under normal circumstances other than tacking/gybing.
The transducer will be connected to my existing Smart Pilot X-5 Wheel. After reading the SPX-5 Setup Guide I believe this will work very well if my rudder mechanical end stops are less than +/- 45° (or 90° stop to stop). And I believe this is the case.
Thanks again for your continued assistance.

You're welcome.
