Connector integrates Ethernet switch & LEDs

This displays both the presence of the Ethernet connection as well as ongoing data exchange and the associated speed information.

By housing the switch functionality in the connector, HARTING’s Han-Modular connector family lends support to the trend toward integrated networking, enabling EtherNet/IP and PROFINET-based communication to be extended over the plant management level control through to the enterprise level.

The module automatically detects the send/receive lines of connected devices and finds the correct settings for the lines. In addition, in conjunction with the 10Base-T and 100Base-Tx interfaces, it autonomously corrects polarity errors in wire pairs and reverses the polarity of the data signal. It also allows two connected Ethernet nodes to autonomously negotiate and configure the maximum data transfer rate (up to 1,000Mb/s incrementally) as well as the type of transmission, i.e. half-duplex or full duplex.

The US4 switch seamlessly integrates into existing Han-Modular systems, with the interfaces required to extend an Ethernet network fitting into existing modular Han connectors.

The Ethernet-based connection of two or more machines involved in a process is a typical application for the Han-Modular US4 switch. The module helps save space, since it can be integrated into a plug connection with the Han-Modular frame with no additional components required.

Other features of the new switch include: an option for the prioritisation of data packets; integrated reverse polarity and overvoltage protection; and high data throughput. A 10-30VDC power supply adapter is also available.
