Chapter 2 Plan a ControlNet Coax Media System
Decide Whether You
Need IP67 Media IP67 media components are sealed ControlNet taps and connectors suitable
for use in harsh environments. The sealed tap contained in the ControlNet
IP67 Tap and Connector Kit (catalog number 1786-TCT2BD1) protects the
taps connection to the trunk with an IP67 rating. The 1786-TCT2BD1
connection to the node via a 1-meter drop cable is a BNC-type connector and
is rated at only IP20.
The BNC drop cable connects to an IP20-rated device, which requires a
protected enclosure in a non-hazardous environment. Therefore, the sealed
tap, containing a 1-meter TNC-to-BNC
drop cable , is protected to a
IP67 rating.
The illustration shows how you can use IP67 media components to protect
non-sealed media in a harsh environment
