Ceramic-Substrate SMT LEDs

Lumex is introducing its KoolBrite™ family of surface-mount LEDs.  These devices have been specifically engineered to meet the toughest thermal dissipating demands.  They utilize Lumex's specially-formulated ceramic substrate material, a unique epoxy lens, and a manufacturing process that can cast the lens directly onto the ceramic substrate.  The result is a family of surface-mount LEDs capable of withstanding even old-fashioned wave soldering, while providing a useable operating life of 50,000+ hours with no loss in light output levels.  KoolBrite™ LEDs virtually eliminate failures due to thermal junction deterioration.

These LEDs are ideal for applications including illumination or indication on PC boards, annunciator and control panels, telecom switches and central office equipment, medical equipment, or anywhere a surface mount LED with exceptional heat characteristics is needed.

Koolbrite™ LEDs are available in two families:  Single Chip and Dual Chip.  All are lead-free.

The Single Chip family uses state-of-the-art chip chemistries to deliver emitted colors including amber, green, red, yellow, and blue.  Intensities range from 30 to 70 mcd at If = 20mA with a very wide viewing angle of 180˚.

The Dual Chip family includes devices with bi-color output.  Product choices include red/green, red/yellow, and yellow/green.  Intensities range from 4 to 12 mcd at If = 20mA with a very wide viewing angle of 180˚.

The exceptional heat characteristics of these LEDs are documented through many tests which include the ability to withstand the 280˚ - 320˚C temperature of a 20W soldering iron for 5 seconds, and a solder dip of 240˚ - 260˚C for 10 seconds.

KoolBrite™ LEDs are available on 8mm tape-and-reel.  In addition to the standard devices, application-specific LEDs can be ordered with options including a choice of colors and lens finishes, or IR emitters and sensors.

Samples of the standard-version devices are available from stock, with production quantities in 8 - 10 weeks.  Pricing varies depending on model specified and quantities ordered, and is approximately $0.25 each in quantities of 3,000.

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.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
