BNC Connectors and Adapters
Overview Some drop cables may require a BNC connector to connect to certain RIO drop
adapters (see Planning RIO Drops, p. 61) or to certain RIO processors at the
controller head-end. Always use industrial grade BNC connectors or adapters in RIO
cable systems—commercial grade hardware should not be used.
BNC Connectors
for RG-6 Cable
The recommended BNC connectors fit RG-6 cable only. Two sizes of BNC
connectors are available for quad shield and non-quad shield RG-6 cables:
z The Modicon 043509446 BNC Connector for quad shield (Consult Sales,
available by special order only)
z The Modicon 52-0487-000 BNC Connector for non-quad shield cable
The following illustration shows the BNC Connector for RG-6 cable.
Note: Quad shield cable has a larger outside diameter, so it requires a larger
connector. Do not use the wrong size BNC connector for the cable you are using.
Belden flexible cables are the only approved non-quad shield cables.
