3.1 Connector Details
All electrical connections are made to the sensor via a 5-way multipole connector located in the base of the wind
sensor housing. The connector pin designations are shown in Figure 9 and the connector/mating connector
manufacturer’s part numbers in Figure 10.

3.2 Cable Details
The mating connectors for the sensor are suitable for use with cables with overall diameters as described in the
table above and for individual cores of diameters of up to 1.2mm. Cable such as SD980CPTP 3x2x0.5mm² from
SAB Brockskes or similar types may be used. Care must be taken to ensure that the cable is suitable for the
environment it will be used in and is adequately approved, for example AWM Style 21198.
In an area with a moderate or severe lightning strike exposure the cable shield may not provide sufficient
protection. In this case the cable will require further shielding such as being enclosed in a metal pipe or conduit.
