New UV LEDs Combine 10X Longer Lifespan and Up To 50% Cost Savings

Lumex announces the global expansion of the QuasarBrite™ UV family of LED technologies to include three new standard wavelengths and also announces the availability of custom UV LED arrays. QuasarBrite UV LEDs provide up to 10 times longer lifespan, up to 50% cost savings , up to 70% energy consumption savings, and superior light performance compared to alternative technologies.

The RoHs compliant QuasarBrite UV LEDs are now available in standard 355nm, 365nm and 377nm wavelengths in a through-hole format. They are ideally suited for a wide range of applications including:
  •     security (counterfeit detection for currency, passports and other travel documents)
  •     forensic (applications related to forensic analysis of bodily fluids)
  •     photo catalyst (for air and water purifier applications in homes, offices and automobiles)
“Previously widespread use of UV LED technology, especially in the shorter UV wavelengths, was hindered because the materials used in the epoxy LED lens degraded the lifespan of UV LEDs to less than 5,000 hours,” explained Kay Fernandez, Product Technology Manager at Lumex. “Recent technological developments have allowed the epoxy lenses to be replaced by a robust TO-46 package with a glass lens, making it possible for QuasarBrite UVs to last 10 times longer- with life spans of over than 50,000 hours.”

In addition to enhanced life span, QuasarBrite UV LEDs provide several key benefits compared to alternative technologies like CCFLs. QuasarBrite UV LEDs provide a uniform beam pattern. To match this performance CCFLs would require a secondary lens resulting in additional cost and space investment. Additionally, QuasarBrite UV LEDs do not use the hazardous mercury material found in CCFL technology and are more durable in their design, thereby significantly reducing maintenance costs. Finally, Lumex’s UV LEDs have up to 70% lower energy consumption than CCFLs. These factors combined allow Lumex’s QuasarBrite UV LEDs to provide up to a 50% cost savings compared to CCFLs.

“Because of significant cost and performance benefits UV LEDs provide over alternative technologies such as CCFLs, there is a dramatic growth in demand for UV LED technology worldwide,” explained Fernandez. “Lumex now offers a total of six standard UV wavelengths (355, 365, 377, 385, 405 and 415nm) as well as an almost limitless number of custom options to meet the needs of this growing market.”

The new 355nm, 365nm and 377nm QuasarBrite UV LEDs feature a 80° viewing angle and operating temperature range from -40°C to 100°C. Samples of these devices are available immediately from stock. Standard and custom production lead times range from 18-20 weeks. Pricing is dependent on quantity ordered, and is approximately $20 to $28 per unit in production quantities dependent on size and quantity ordered.

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.
