Model: ENHSAURR8
Ethernet Machine Mount Switch
Overview
Ethernet networks consist of a star topology—all transmissions pass through a central device. The
repeater hub is the simplest form of such a device, but has limitations in industrial applications:
• If more than one Ethernet device transmits at the same time, a data collision will occur, forcing each
station to retransmit in order to deliver its message.
• Hubs must transmit messages from all ports to reach the intended receiver, creating inefficient
bandwidth usage.
Ethernet switches, however, allow all devices to transmit simultaneously, without collision. This is
essential for enabling deterministic delivery of time-critical information. Switches are intelligent devices,
keeping track of device locations. This allows messages to be transmitted only from the necessary port,
leading to improved network performance.
Introduction
The ENHSAURR8 is an 8-port switch designed to operate without the need for any type of enclosure. The device can be mounted
anywhere (side of a machine, building pillar, on an oil rig), providing for network design flexibility.
• IEC IP67 Rating, when used with RJ-Lnxx cord sets, prevents contamination from dirt, oil & water.
• Unsurpassed temperature operating range (-40˚ to 80˚ C) allows use in both the hottest and coldest conditions, without the need for
environmental controls.
• Class I/Div 2 rated for use in hazardous environments.
• Store & forward switch with address auto-learning and 10/100 auto-negotiation enhances bandwidth efficiency, aiding determinism
for control applications.
• No programming required, allowing the switch to be installed and carrying data in minutes.
