Product Description
The RF40 is a medium-duty rudder feedback unit for use with NAC-1 and NAC-2 autopilot systems.
Rudder feedbacks measure and report actual rudder angle to your autopilot computer, enabling precise rudder control for smooth and accurate steering.
Direct Connection for Simple Plug-and-Play Installation
The RF40 is designed for direct connection to NAC-1 and NAC-2 autopilot computers, with variable voltage output and an attached 15 metre (49 foot) cable with plug-and-play connector.
The connector can be easily removed for use in other applications.
Its extended cable and direct connection make the RF40 an ideal alternative to NMEA 2000® connected sensors, such as the RF25, in situations where it is impractical or otherwise unnecessary to extend a vessel’s NMEA 2000® network within reach of the rudder.
- ±120-degree rudder angle measurement
- Plug-and-play connection to NAC-1 and NAC-2 autopilot computers
- 15 metre (49 foot) attached cable
