Dialight Launches First FAA-Certified L-864 Red Beacon with Integral IR LEDs

Dialight (LSE: DIA.L), the market leader in LED obstruction lighting, today announced the availability of its new Vigilant L-864 Infrared (IR) LED-based Medium Intensity Red Beacon, the first product of its kind incorporating both red and IR LEDs in a single unit.  The product has been FAA certified to 150/5345-43F. The IR integration ensures better visibility for aircraft pilots using Night Vision Goggles (NVGs) and Aviator’s Night Vision Imaging Systems (ANVIS) for improved safety near military bases and airfield perimeters within the most energy-efficient L-864 beacon in the industry.

The new IR beacon is the newest innovation in Dialight’s decade-long history of delivering the most energy-efficient LED obstruction lighting solutions for towers, buildings, smokestacks and more. The company continues to expand its integrated IR product line; the IR L-864 beacon now joins Dialight's IR L-810 side marker light, the first-ever LED obstruction light certified to 150/5345-43F with integral IR LEDs.

“Dialight leads the LED obstruction lighting market with superior technology and innovation that is shaping the future of aviation navigation,” said Roy Burton, Dialight Group Chief Executive. “This latest product delivers exceptional energy efficiency, virtually zero maintenance and built-in IR technology that eliminates the need for bolt-on systems that add to both wind resistance and maintenance costs.”

NVGs and ANVIS typically employ Class A, B and C filters that can reduce visibility of typical LED light sources. Unlike other beacon systems that require separate IR units, the Vigilant IR beacon incorporates night-vision-friendly IR LEDs and red LEDs in the same unit, leveraging the same compact design of Dialight’s standard L-864 to produce the smallest and lightest-weight flash head  on the market. This smaller footprint significantly reduces wind load compared to incandescent L-864 beacons and makes for much easier installation. The multi-patented system also features community-friendly optics for minimum ground scatter. The system offers a peak IR spectral intensity at 860 nanometers.

A new hinged lid design enables easy access to terminal block wiring for installation and power supply maintenance. Control circuitry may be located at the base of the tower for better protection against lighting, while the IP66 certified beacon design is factory sealed for durability and rugged performance in the harshest conditions, even at operating temperatures ranging from -40°F to 131°F (-40°C to +55°C). With a 10-year LED life expectancy, backed by Dialight’s 5-year full-performance warranty, the Vigilant IR L-864 beacon dramatically reduces maintenance costs, virtually eliminating expensive tower climbs, unplanned site visits and the risk of non-compliance fines due to burned-out bulbs.

In addition to exceptional maintenance savings, the unit is also extremely energy efficient to save on electricity costs, drawing only a small fraction of the power required by a typical 1400W incandescent system. Rated at just 40W, the Dialight IR L-864 operates at 6.7W on a normal 16.7% duty cycle of 20 half-second flashes per minute. The typical incandescent draws more than 230W on the same cycle. This low-power consumption also provides for extremely low RF interference, making it ideal for lighting “hot” AM towers with no disruption in signal transmission.

The Vigilant IR L-864 can even be adapted to existing incandescent beacons for a future-proof system. Should the red beacon fail on a dual incandescent, the IR L-864 can be synchronized with the existing white incandescent, to get the maximum possible useful life out of the existing technology.

In addition to FAA certification, the IR L-864 is also compliant with the ICAO Annex 14 and Aerodromes Design Manual European specification and Transport Canada’s Canadian Aviation Regulation CAR 621.19.

Dialight’s products are listed on the U.S. federal government’s GSA Schedule 56 for Buildings and Building Materials/Industrial Services and Supplies under contract number GS-07F-0664X.

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.

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.
