L-GAGE LH Series Laser Sensor is High-Speed, High-Precision, Non-Contact Measurement Sensor



High-precision, high-speed, and high-performance are just some of the words used to describe the new L-GAGE LH Series laser sensor from Banner Engineering. The LH Series is used for precision displacement and thickness measurements, and was developed to solve demanding measurement and quality control inspections. The LH Series is a non-contact measurement sensor that provides accurate and stable measurement on materials such as wood, metal, rubber, ceramic, and plastic parts. It is an extremely accurate, robust, and self-contained laser displacement sensor using a 1024 pixel CMOS linear imager that can achieve up to a 1 micron resolution under nominal conditions.

"What sets the LH Series sensors apart from traditional laser sensors is the linear imager and its ability to be used on a wider variety of materials, reflective surfaces, and colors," said Dean Tyo, Chief Engineer for Vision, Measurement, and Instrumentation at Banner. "Therefore, the LH allows us to provide continuous non-contact measurements in a greater number of industries and applications that involve moving processes, stamped and machined parts, and soft or sticky parts."

The new LH also features both a high resolution 4-20 mA and RS-485 serial communication outputs for target displacement measurements, a narrow laser spot for small targets, and the visible spot aids easy alignment to the target. Two sensors can be configured to self-synchronize for thickness measurements with the thickness calculation performed within the sensors, which means no external controller is required. The LH can also be used in a network of up to 32 sensors to do multiple simultaneous inspections.

The LH sensor comes with an intuitive Graphical User Interface (GUI) which guides the user through setup and performance monitoring when adjusting the sensor parameters. After the LH is installed, the GUI provides data acquisition tools to graphically display the current measurements. Parameters such as analog output scaling, averaging, sample size, and other advanced features can all be set within the GUI. All data is displayed in real time and can be saved to a log file, which is useful for troubleshooting the installation.

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.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon.
