High-Speed Backplanes: Data Transfer up to 40 Gb/s

Demands for ever higher data transfer in systems of various bus technologies continue to rise. This began with AdvancedTCA systems. The chipsets for the next generation of serial protocols, e.g. 10 Gb/s Ethernet (10 G base-KR) or SRIO Gen2 are either already available or will come onto the market shortly. For PCI Express there are, for example, already drivers for Gen2 with a transmission rate of 5 Gb/s per port, and the next step to Gen3 with 8 Gb/s is expected soon. For serial ATA, which currently has a transmission rate of 3 Gb/s, revision 3 has also been defined with a doubling of the data rate to 6 Gb/s. The development of boards and switches for the new high-speed generation of this software protocol is in full swing. And this is the case not only for the AdvancedTCA platform but also on all new system high-speed standards such as VPX, CompactPCI Serial and MicroTCA. Here also, users are demanding systems that support ultra-fast new software protocols. This means that the appropriate backplanes must also be designed to carry data at these new high rates.

With innovative design, and secured by extensive testing, Schroff is already manufacturing AdvancedTCA backplanes with data rates of 40 Gb/s today (10 G base-KR on 4 parallel ports). However, all other new Schroff backplanes and systems for VPX, CompactPCI Serial and MicroTCA have been developed and tested on the basis of these new generations of software protocols. The growing requirements for cooling and power supply have likewise been taken into account. As a result Schroff is already now in a position to offer systems of various bus technologies that support all new software protocols. Customers can find detailed information on this on the Schroff website and in the user manuals available there.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…
