Figure 9: Mounting the High-Density, 60 Pin Connector
OEM7 receivers have an area on the edge of the cards to allow the use of mounting rails. This is
the area of bare copper outside of the keep-out zone. On the OEM719, OEM7700 and OEM7720,
this area is 1.75 mm wide. On the OEM729, this area is 2.5 mm wide. See
Figure 48: OEM719
Mounting Surface on page 135, Figure 51: OEM729 Mounting Surfaces on page 151, Figure 54:
OEM7700 Mounting Surfaces on page 171 and Figure 57: OEM7720 Mounting Surfaces on
page 195 for the dimensions of this area.
For most non-demanding applications (e.g. base stations, remote sensing, desktop units and IT
infrastructure), standoffs or bosses are sufficient to provide a secure mounting location.
Using rails to mount the OEM7 receiver improves the thermal and vibration performance of the
receiver. Securing the OEM7 receiver to mounting rails using additional rails as clamping bars
provides the most secure configuration for aggressive thermal and vibration applications. See
Table 1: NovAtel Mounting Rails below for information about the OEM7 mounting rails available
from NovAtel.
