Fujitsu Introduces New FRAM-based Device for Radio Frequency ID Applications

Fujitsu Semiconductor America has introduced a new FRAM-based device with the industry’s highest memory capacity for a high-frequency RFID (radio frequency ID) IC.

The MB89R112 is the latest member of the Fujitsu FerVID Family™, which uses FRAM memory for fast write speeds and high-frequency rewriting capabilities, providing excellent radiation tolerance and low-power operation. The device includes 9 kilobytes (KB) of FRAM, with a full 8 KB available as user memory. Memory is structured as 256 blocks of 32 bytes per block, permitting read and write access to the entire 8 KB region defined in ISO/IEC15693. Writing 8 KB of data takes about four seconds, a high-speed operation six times faster than products using EEPROM.

The MB89R112 operates at 13.5 MHz +/- 7kHz and assures data retention for up to 10 years. In addition to its wireless HF interface, the dual-interface MB89R112 incorporates a wired serial interface (SPI) for microcontroller connectivity.

Supplying more available data on RFID tags enables efficient use in various applications, and the combined features of the MB89R112 create new options for RFID use in embedded and industrial designs. Examples include facilitating wireless modification of product operating parameters, logging environmental readings for logistics, detecting equipment errors, modifying electronic displays, altering sensor threshold values, and changing firmware settings. Capabilities like these can enhance production control in automotive and electronics manufacturing. They can also help with maintenance applications in aviation, road building, construction and civil engineering.

“The MB89R112 meets the market need for higher capacity memory with an RFID interface to sensors and microcontrollers,” said Tong Swan Pang, senior manager of marketing at Fujitsu Semiconductor America. “The dual-interface FRAM-based RFID enables customers to log, store, modify and exchange data flexibly between wireless RFIDs and wired embedded systems.”

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.

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

The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…

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.
