Connecting radar sensor
Connections to radar sensor
Each radar sensor requires a power and a data connection. Both are made using military specification connectors to ensure link integrity. The power and data connections run from the sensor to a conveniently placed junction box (e.g.at the base of the post) where the power supply is situated. See Figure 12.
IMPORTANT: Failure to correctly fit the shroud can invalidate the warranty on sensors that have been caused to fail through water ingress.Supplied with each radar sensor are a power cable with a mil-spec connector for the sensor connection and a bare end at the junction box connection. A mil spec shroud is also supplied for use with a suitable environmentally protected Ethernet network connection. It is essential that the supplied shroud is correctly used to ensure that the data connection is water tight.
- Attach 24vDC connection to the radar.

- Ensure the Power and Ethernet cables are securely connected into junction box.
- Ensure the junction box has the Navtech supplied 24vDC power supply installed. (The power supply unit has a peak current capacity of 4 Amps, though typically the radar draws a continuous 1 Amp). See.[8].
- Ensure that the Power supply cabling is correctly terminated at the radar end with a secure Amphenol MIL spec connector. Pin D (Red or Brown) is 24vDC, Pin J (Blue or Black) is 0V.
IMPORTANT: To prevent floating voltage levels on the low output of the radar sensor power supply unit, link the 0v output to earth.
- IMPORTANT: When connecting data and power cables to radars in harsh or corrosive environments Navtech recommends the use of Chesterton 740 as a product to protect the military specification connectors from corrosion. This is a recommended best practice. Failure to apply the product could mean extra field time for engineers and the costs that this will incur. SEE: Error!
