Rugged, 14-port Gigabit Managed Ethernet Switch with 2 SFP Sockets from Diamond Systems

Standalone Layer 2+ Ethernet switch targets harsh environment applications

Mountain View, Calif. December 2013 - Diamond Systems, a global developer of compact, rugged, I/O-rich embedded computing solutions for a broad range of real-world applications, today unveiled Epsilon-12G2. The rugged, managed Layer 2+ Ethernet switch module offers twelve 10/100/1000 Mbps copper twisted pair ports and two small form factor pluggable (SFP) sockets in a compact COM Express form factor.


The new standalone switch does not require any host computer interface. A 480 MHz MIPS processor embedded directly into the switch manages all switch functions. The processor is accessed via an in-band web interface over one of the Ethernet ports or via an out-of-band command-line interface over an RS-232 serial port. The integrated web interface provides an intuitive GUI for configuring and managing all switch functionality.

On-board memory holds dual application images, boot code, MAC addresses and other parameters, and can also be used for program execution.

Designed for use in rugged applications including industrial, on-vehicle and military environments, Epsilon-12G2 operates over an extended temperature range of -40°C to +85°C. All I/O connectors are latching, providing enhanced reliability over the RJ-45 connectors used in commercial Ethernet switches. A 50% thicker PCB provides better protection against vibration in vehicle environments. The +5 V to +40 V wide range DC/DC power supply is compatible with all common vehicle and industrial power sources.

The switch's dual SFP socket interfaces to 1 G fiber Ethernet networks. One port can operate at an enhanced 2.5 G to support efficient stacking of two switches together for a combined total of 26 ports.

Epsilon-12G2 comes with all the required firmware preconfigured, enabling immediate operation without any development effort.

Schmalz Technology Development - Vacuum Generation without Compressed Air - Flexible and Intelligent

• Vacuum generation that's 100% electrical; • Integrated intelligence for energy and process control; • Extensive communication options through IO-Link interface; Schmalz already offers a large range of solutions that can optimize handling process from single components such as vacuum generators to complete gripping systems. Particularly when used in autonomous warehouse, conventional vacuum generation with compressed air reaches its limits. Compressed air often is unavailable in warehouses. Schmalz therefore is introducing a new technology development: a gripper with vacuum generation that does not use compressed air. The vacuum is generated 100% electrically. This makes the gripper both energy efficient and mobile. At the same time, warehouses need systems with integrated intelligence to deliver information and learn. This enables the use of mobile and self-sufficient robots, which pick production order at various locations in the warehouse. Furthermore, Schmalz provides various modular connection options from its wide range of end effectors in order to handle different products reliably and safely.
