Rugged, Lightweight 7” Display from IEE Offers Exceptional SWaP-C Performance

IEE, Inc., specializing in the design, test, support and fielding of human system interface (HSI) display technologies in a wide range of military/aerospace, industrial and retail applications, now offers a rugged 7” browser control display unit (B-CDU) that offers exceptional SWaP-C properties with enhanced graphics capabilities.

The new, low cost display combines low power consumption of only 5 W with high processing for increased reliability, making it useful in a large number of new and existing military applications, such as smart driver displays, vetronics displays and graphics or video enabled control units. The intuitive operator interface also makes the B-CDU ideal for logistics support, condition-based maintenance (CBM) and embedded training.

By using an advanced, highly integrated ARM processor operating at 720 MHz, the rugged, flat panel touch display can accommodate both embedded video decoding as well as 2D/3D graphics processing. This gives system engineers greater flexibility to incorporate the latest in video/graphics performance into new and existing embedded designs.

The new B-CDU operates as a thin-client network device for easy integration into display systems. Its COTS-based Linux operating system provides simple programming while the industry-standard 10/100Base-T Ethernet communication protocol and HTML 5.0/JavaVM software support enable the display to function as a simple web device. Existing web-based graphics and screens can easily be viewed and refreshed on the B-CDU.

Whether used as a hand-held or vehicle-mounted display, the new 7” unit offers a WVGA color transflective LCD with a resolution of 800 x 480 x RGB, readable in a wide range of ambient lighting conditions from night vision imaging system (NVIS) to sunlight. It comes in a lightweight, yet highly durable, composite housing. The integral resistive touchscreen is enhanced with a single row of five sealed dome switch snap-keys designed to be operated in the most severe environments, such as with MOPP-IV gloves or Arctic mittens.

Intrinsic military intelligence features include a ‘zeroize’ function that clears the system memory in an emergency situation as well as a ‘covert’ switch that immediately turns off the display and key backlights to prevent device detection in mission-critical conditions.

Typical display brightness is 550 cd/m2 with horizontal and vertical viewing angles of ±80 degrees. High ambient readability, measured as contrast ratio, is enhanced through the use of a transflective display technology and the application of enhancement filters and AR/AG films. The B-CDU weighs only 2 lbs and features an operating temperature of -20°C to +71°C in altitudes up to 36,000 ft, with operation down to -40°C available with an optional heating unit.

The display meets or exceeds the following specifications: MIL-STD-810 for environmental considerations; MIL-STD-461/462 for EMI and EMC; MIL-P-7788 for panel construction; MIL-STD-3009 for NVIS; and MIL-STD-704 and MIL-STD-1275 for power. It also can withstand submersion in 3 feet of water for 2 hours.

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.

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.
