Ethernet Connectors

As mentioned previously, Cat5e Ethernet cables use RJ45 plugs. Each REAC device provides an RJ45 receptacle for its REAC ports.

Though the standard RJ45 connection is very reliable, in high-traffic installations you may want to protect the connection between the RJ45 plug and its receptacle. To this end, REAC RJ45 receptacles utilize rugged Neutrik® EtherCon® connectors. When used with RJ45 plugs housed in EtherCon connectors, this provides a robust latching connection similar to that provided by an XLR connector.

Neutrik offers EtherCon connectors for the fabrication of new cables (models NE8MC-1 and NE8MC-1-B), and EtherCon connectors that can be added to a pre-made Ethernet cable (models NE8MC and NE8MC-B).

A REAC port’s RJ45 receptacle can accept either a regular RJ45 plug or one housed in an EtherCon connector.
