Simrad NAC-2 Autopilot RF25N Feedback Core Pack

Description

Use physical rudder-position feedback with the Simrad NAC-2 RF25N Feedback Core Pack, which includes a NAC-2 course computer, Precision-9 nine-axis solid-state AHRS, RF25N rudder-feedback sensor, and NMEA 2000 starter kit. The pack is specified for sailboats, displacement yachts, and inboard power vessels with mechanical tillers, inboard rudder hydraulic lines, or cable-drive helms. Its physical feedback sensor supports installations requiring rudder-position tracking.

Hydraulic-cylinder capacity is specified up to 250 cc, or 15.2 cubic inches. The NAC-2 supplies 8A continuous output with up to 16A peak, while the system supports 12V or 24V DC power. The core unit has an IPX5 rating, and the RF25N sensor has an IPX7 rating. Combined weight is 1.8 kg, or 4.0 lb, before adding the separate drive and display components.

Key Specifications of the Simrad NAC-2 RF25N Feedback Core Pack

• The pack includes a NAC-2 course computer, Precision-9 nine-axis AHRS, RF25N feedback sensor, and NMEA 2000 starter kit.
• Sailboats, displacement yachts, and inboard power vessels can use the pack with compatible tiller, hydraulic, or cable-drive steering systems.
• The RF25N sensor provides physical rudder-position feedback for installations requiring measured steering-geometry synchronization during system setup.
• Hydraulic-cylinder capacity is specified up to 250 cc, or 15.2 cubic inches, requiring exact cylinder-volume verification before selection.
• The NAC-2 provides 8A continuous output with 16A peak drive capacity for compatible linear, hydraulic, or rotary autopilot drives.
• Operating voltage supports 12V or 24V DC systems, while full locked-loop load can reach 20A intermittently during operation.
• The NAC-2 has IPX5 protection and the RF25N carries IPX7 protection for the documented component environmental ratings.

System Integration and Feedback

This Simrad core pack does not include the separate steering drive or helm display needed for a complete autopilot installation. The NAC-2 course computer manages the selected drive, the Precision-9 supplies heading and attitude data, and the RF25N provides physical rudder-position feedback. Each component must be matched with the vessel’s steering configuration and NMEA 2000 network.

Physical rudder geometry synchronization is specified as part of the dockside setup process. Continuum Steering Technology, wind-vane tracking, and virtual-pivot controls are stated compatible system functions. Actual system behavior depends on the selected drive, sensor installation, vessel steering geometry, electrical supply, and complete autopilot commissioning.

Why Choose the Simrad NAC-2 RF25N Feedback Core Pack

The Simrad NAC-2 RF25N Feedback Core Pack combines a NAC-2 computer, Precision-9 nine-axis AHRS, RF25N rudder sensor, and NMEA 2000 starter kit. Its physical rudder-feedback arrangement, 250 cc hydraulic-cylinder limit, 8A continuous output, 16A peak output, 12V or 24V supply, IPX5 and IPX7 component ratings, and 1.8 kg combined weight help buyers assess whether physical feedback is required instead of a VRF-based configuration.

Setup and Network Considerations

Confirm that the vessel requires physical rudder-position feedback and has a compatible tiller, hydraulic, or cable-drive steering arrangement before selecting this core pack. Verify hydraulic-cylinder volume where applicable, select the required drive and display, and plan NAC-2, Precision-9, and RF25N mounting positions. Check NMEA 2000 connections, 12V or 24V supply, 8A continuous output needs, and installation geometry before starting dockside setup.

Warranty and Support

Simrad warranty terms vary by product and region, and the supplied specifications do not provide a named warranty period for this core pack. Mulmarine.com can help you review RF25N feedback requirements, steering type, hydraulic-cylinder volume, drive selection, sensor placements, NMEA 2000 network needs, power capacity, and separate display requirements before purchase. Review the applicable Simrad warranty coverage and documented package contents before ordering.

Before Ordering the Simrad NAC-2 RF25N Feedback Core Pack

Confirm that your vessel requires an RF25N physical rudder-feedback sensor and uses a compatible tiller, hydraulic, or cable-drive steering arrangement. You should verify the steering-drive requirement, cylinder volume up to 250 cc where applicable, NAC-2 and RF25N mounting locations, Precision-9 sensor placement, NMEA 2000 capacity, 12V or 24V supply, 8A continuous and 16A peak drive requirements, and full commissioning needs before purchase.
