About the Isolated Bulkhead Connector

The isolated bulkhead connector is a device used to allow ControlNet cable trunk lines to
pass through metal enclosures. The isolated bulkhead connector prevents the ControlNet
cable from inadvertently being grounded to metallic surfaces that may cause noise on a
network. Any number of isolated bulkhead connectors can be placed in a system.
