Murata launches world's smallest HF-band RFID tag for faster reading of more data

Murata Manufacturing Co., Ltd. (TOKYO: 6981) (ISIN: JP3914400001) is going to launch mass production of the world's smallest HF-band RFID*1 tag (3.2 x 3.2 x 0.7mm) . Murata has applied its proprietary multi-layer circuit board technology and high-frequency module technology, with which the successful miniaturization of an RFID tag to one-tenth the size of an RFID tag composed of plane surface, was achieved.

The company will exhibit this product at "CEATEC JAPAN 2012", which will be held at Makuhari Messe in Chiba Prefecture from October 2nd to 6th, 2012.

"This innovative RFID tag is an ultra-small component that has been developed by integrating multi-layer circuit board and high-frequency module technologies, Murata core competencies. " says Mr. Hideharu Ieki, Executive Vice President Technology & Business Development Unit Member of the Board of Directors. "In addition to contactless IC cards, which are rapidly becoming widespread, this RFID tag can be attached to various objects to provide, for example, connections with a smartphone. Murata intends to respond flexibly to various potential customer needs and new application use cases in various fields."

RFID*2 indicates technologies in general that exchange information using near-field wireless communications from an IC tag embedded with ID data. Recently, RFID is being used for contactless IC cards such as prepaid fare cards on train lines and e-money, significantly increasing the convenience of our lifestyles. Murata introduced the RFID device "MAGICSTRAP®" to the market in 2008. Until now, "MAGICSTRAP®" has been used for manufacturing process management and other applications.

Normally, an RFID device consists of an IC tag and antenna. Because the HF-band RFID tag uses low frequencies, the size of the RFID antenna tends to become extremely large. Therefore, it is believed that there is a limit to miniaturization of RFID devices. In an effort to resolve this issue, Murata applied multi-layer circuit board and high-frequency module technologies that the company has developed over the years to configure the antenna inside the ceramic substrate. As a result, it has successfully miniaturized an RFID tag to one-tenth the size of the RFID tag composed of plane surface. Furthermore, the new RFID product uses a ceramic module structure that makes it highly resistant to the environment and enables it to achieve stable operation under various environmental conditions.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
