Sensor Mounting
The 3DM-CX5-GNSS/INSsensor housing is rated for indoor use only, unless used inside a protective
enclosure. When using the internal GNSS receiver, the GNSS antenna connector on the side of the
sensor must be accessible. The connector and cable must be non- magnetic. The MMCX to SMA
adapter cable supplied with all 3DM-CX5-GNSS/INS is non-magnetic.
The sensor has two mounting tabs with holes for fastening. Mounting screws should be brass or 300
Series stainless steel. Nylon washers and thread-lock are recommended. There are two additional
holes used for precise alignment with 2mm dowel pins. One of the holes is slotted to allow for relaxed
pin positioning accuracy. The sensor can be mounted in any orientation, as required for the application
(
see Sensor Reference Frames on page 29
). The axes are labeled on the face of the sensor for
reference, and the sensor measurement origin is shown in the sensor dimensional drawing (
