The EXTreme Guardian™ System by Molex Receives DesignVision Award; Delivers Compact, High-Power Header and Cable Solution for the Top-End Server Market

Molex Incorporated today introduced the EXTreme Guardian™ header and cable solution for high-end servers in the computing and telecommunication markets. Recognized with the 2012 DesignVision Award in the Interconnect Technologies and Components category, this next generation solution features a three circuit, wire-to-board configuration that delivers up to 80 Amps of current per circuit, a PCB header with centerline spacing of 11.00 mm (0.433”) for increased PCB real estate savings and an EMI-shielding option to reduce cable crosstalk and improve immunity to external noise.

“Winning the prestigious DesignVision Award recognizes the innovation of the EXTreme Guardian solution. When developing the system, the Molex technical team focused on several critical requirements expressed by customers, including small package size, high amperage support and good shielding characteristics,” said Ken Stead, new product development manager, Molex. “By gaining a full understanding of these needs, we were able to develop a solution to meet all of the unique physical, mechanical and electrical specifications required by the end user.”

The EXTreme Guardian PCB header assembly reduces network downtime with a recessed, first-mate/last-break terminal that allows for hot-swapping of power units. The headers also include several unique design features, such as insert-molding for higher insert placement accuracy, integral screw threads on the header housing flange for easy and secure mating and locating pegs that enable accurate through-hole positioning of the connector.

The EXTreme Guardian cable assemblies are capable of handling up to 600 V, supporting high voltage with the lowest feasible voltage drop and I2R (irreversible dissipative power) losses. Other mechanical features of the cable solution include thumb-screws on the cable overmold that can withstand a minimum extraction force of 1.5 kgf (3.3 lb), a jacket-included strain-relief that can take a minimum pull force of 9.98 kgf (22 lb) in any direction and a secondary terminal lock to secure the cable from accidental pull out and disconnection.

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…

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…

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.
