Unmanaged Ethernet switches in IP67 protected metal housings

04 July 2015

Murrelektronik's TREE67 series unmanaged Ethernet switch is equipped with four or eight M12 ports for applications in harsh industrial environments.

The units, which can be used to implement decentralised machine configurations in star topology, are immune to EMC interference and resistant to vibration; they are also capable of working over the wide temperature range of -25°C to +60°C.

The four or eight M12 connections (d-coded) support transfer rates of 10 or 100MBit/s. With the auto-negotiation function, the devices automatically detect which rate is currently needed. VLAN tagged Profinet frames always have the right-of-way, and are automatically prioritised.

TREE67 is an unmanaged switch - it does not need to be configured - so various devices can be quickly and conveniently connected with 'plug-and-play' simplicity. An auto-crossing function automatically detects which cables are connected to the ports, thus eliminating wiring errors. The power supply offers redundancy to ensure reliable operation, while integral LEDs provide visual indication of operation and data rate.
