The best listed choice for a rudder angle reading on an NMEA 2000 network is a KUS 52 mm or 85 mm meter-and-sensor package, both described as transmitting NMEA 2000 signals. The 52 mm version suits buyers who need a smaller installation opening; the 85 mm version is for a larger display. VDO’s single- and dual-station sensors and ELING’s resistive sender are alternatives, but their supplied product details do not confirm NMEA 2000 output.
| Product | Best suited for | Signal information provided |
|---|---|---|
| KUS 52 mm meter and sensor | Compact instrument installation | NMEA 2000 |
| KUS 85 mm meter and sensor | Larger instrument opening | NMEA 2000 |
| VDO single-station sensor | Single-station installations to verify | Not specified |
| VDO dual-station sensor | Dual-station installations to verify | Not specified |
| ELING sender | Systems designed for resistive input | 0–190 ohm |
KUS 52 mm NMEA 2000 Rudder Angle Meter
This is the most directly specified compact option in the list. The product description says its sensor outputs NMEA 2000 signals and that the included meter receives the signal to drive a stepper-motor display. It reports a rudder range of 0 to ±165 degrees, 12-bit angle resolution, and 12V/24V working voltage.
Best for: Buyers seeking a package with both a stated NMEA 2000 signal and a 52 mm instrument size. The description also identifies non-contact operation and standard NMEA 2000 network transmission.
Check before buying: Confirm the required panel cutout and network connections for your boat. The listed display range is R-L, so verify that its markings and orientation suit your helm.
KUS 85 mm NMEA 2000 Rudder Angle Meter
This larger KUS package has the same key signal and angle details as the 52 mm model: NMEA 2000 transmission, a 0 to ±165-degree rudder range, 12-bit angle resolution, and 12V/24V working voltage. The stated installation size is 85 mm.
Best for: Owners whose instrument layout calls for an 85 mm opening and who want a dedicated meter alongside the sensor. Choose this over the 52 mm model when the larger installation size fits the helm design.
Check before buying: The larger size requires more panel space. Measure the installation area and confirm the display’s network and power requirements before ordering.
VDO Single-Station Rudder Angle Sensor
This Veratron/VDO sensor is listed for a single station and is identified as a 12/24V rudder angle sensor. That makes it a possible option for a helm setup with one station, but the supplied features do not state that it outputs NMEA 2000 data.
Best for: Buyers looking for a single-station sender who can confirm its output type and compatibility with their existing instruments or network equipment.
Check before buying: Do not assume that the 12/24V specification means the sensor connects directly to an NMEA 2000 backbone. Verify the signal format and any interface requirements with the product documentation.
VDO Dual-Station Rudder Angle Sensor
The product name identifies this VDO sensor for a dual-station arrangement. The available feature information is limited to a general boat-outfitting and gauge classification; it does not provide a signal type, voltage, or NMEA 2000 specification.
Best for: Buyers with two operating stations who are considering a dual-station sensor and can check its wiring and output requirements before purchase.
Check before buying: The listed data does not establish NMEA 2000 compatibility. Confirm whether the sensor provides a network signal directly or needs a separate converter or compatible display.
ELING 0–190 Ohm Rudder Angle Sender
ELING’s sender is specified with a 0–190 ohm resistance output, a maximum rating of 500 mW, and a working temperature range of -40 to 85°C. Its stated output is resistive rather than NMEA 2000.
Best for: Buyers whose existing gauge or system is designed to read a 0–190 ohm sender. It may be a relevant alternative when matching a resistive input is more important than direct network transmission.
Check before buying: Avoid treating this as a direct NMEA 2000 sensor. Confirm that the receiving equipment supports its resistance range or that an appropriate interface is available.
Buying Guide: Choosing A Rudder Angle Sensor
Does the sensor transmit NMEA 2000 data?
Start by checking the stated signal type, not just the product name or voltage. In this list, the KUS packages explicitly describe NMEA 2000 output. The VDO listings do not specify their signal format, while the ELING sender specifies resistance output. Ask for documentation if network compatibility is not clearly stated.
Do you need a meter as well as a sensor?
The KUS listings describe a sensor used with a matching rudder angle meter. That can suit buyers who want a dedicated helm display. If you only need data on an existing chartplotter or other network display, confirm that the sensor provides the required network data and that your equipment can display it.
Which installation size should you choose?
Compare the listed 52 mm and 85 mm installation sizes with the available panel opening and the instrument layout. Measure before selecting a meter. For the VDO and ELING products, the supplied details do not provide an instrument cutout size.
What power and angle range should you verify?
The KUS descriptions state 12V/24V operation and a 0 to ±165-degree range. Check that the sensor and display requirements fit your boat’s electrical setup and steering arrangement. Do not assume those specifications apply to the VDO or ELING models, because they are not provided in the supplied product details.
Frequently Asked Questions
Which listed product explicitly supports NMEA 2000?
Both KUS meter-and-sensor packages explicitly describe NMEA 2000 signal transmission. The supplied details for the other three products do not confirm direct NMEA 2000 output.
Is a 0–190 ohm sender the same as an NMEA 2000 sensor?
No. The ELING product is specified as a resistive sender. It requires receiving equipment that supports that signal or a suitable interface.
What is the difference between the two KUS sizes?
The listed installation size is 52 mm for one model and 85 mm for the other. Both are described with NMEA 2000 transmission, 12V/24V working voltage, and a 0 to ±165-degree range.
Can a VDO sensor connect directly to an NMEA 2000 network?
The available product details do not say. Confirm the sensor’s output type and any required network interface before purchasing.
