Littelfuse LSP05/LSP10 Series Surge Protection Device Modules Win ACE (Annual Creativity in Electronics) Award

Littelfuse, Inc., the global leader in circuit protection, today announced its LSP05/LSP10 Series Surge Protection Device Modules were named a winner in the EE Times and EDN 2015 UBM Canon ACE Awards in the “Ultimate Products: LEDs and Lighting” category. The awards program honors the people and companies behind the technologies and products that are changing the world of electronics.

The winners were announced at an awards ceremony on Tuesday, July 21, at the Santa Clara Convention Center, during the Embedded Systems Conference Silicon Valley. Bharat Shenoy, the director of technical marketing at Littelfuse, was on hand to receive the award. He noted, “I know everyone at Littelfuse, especially those on the product development and marketing teams, feels very honored today by this award. The LSP05 and LSP10 Series products represent the collective efforts of many people striving to offer our customers the most advanced and cost-effective circuit protection solutions available.”

Constructed with Littelfuse thermally protected varistors, the LSP05 and LSP10 Surge Protection Device (SPD) Modules provide robust surge current handling capability. These optimized surge immunity solutions protect outdoor LED fixture investments with maximum lightning surge current ratings of 20,000A (LSP10) and 10,000A (LSP05). Their compact form factor (48x48x30mm) makes them easy to mount inside a luminaire; mounting tabs simplify installation and replacement. A built-in thermal disconnect function provides additional protection from catastrophic failures and fire hazards, even under the extreme circumstances of varistor end of life or sustained overvoltage conditions.

Metal Oxide Varistors (MOVs) used to protect LED luminaires degrade gradually after a large surge or multiple small surges. This leads to increasing MOV leakage current, raising MOV temperature under normal conditions. A thermal disconnect like that used in the LSP05 and LSP10 senses this temperature increase as the MOV approaches its end-of-life condition, at which point it will open, removing the MOV from the circuit and preventing its catastrophic failure.

“We are continually amazed at the level of creativity in the design, innovation and technology exemplified by these award winners,” said Suzanne Deffree, Executive Editor at UBM Canon's EDN. “The ACE Awards celebrate the highest achievements in innovation and creativity in electronics design, and selecting one organization or individual that stands out above the rest is incredibly challenging. We are pleased to be able to celebrate their achievements.”

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.

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.
