AR RF/Microwave Instrumentation has upgraded its line of laser-powered star probes with a new electric field probe, that replaces the previous model FL7018. The new model, FL7218, contains an internal microprocessor to provide linearization, temperature compensation, control and communication functions. The probe's noise reduction and temperature compensation allow accurate … [Read more...]
Hall Effect Sensors with Input Reference Pin
Premo’s new series of Hall Effect sensors, the DSR5 series, is a close loop technology component in a small package for THT mounting. Primary winding is already integrated, which allows it to measure DC, AC and pulse currents on printed circuit boards.The DSR5 series includes an external pin that allows access to the internal reference (2.5V). This pin can be used as an output … [Read more...]

President Obama Launches Manufacturing Initiative
President Obama recently announced a new partnership between the government, industries and leading universities to speed the movement of technological advances to commercial users. Mr. Obama said federal agencies would invest more than $500 million to seed the initiative. Of that, $70 million is to go to robotics projects such as a boom-box-size robot that inspects sewer … [Read more...]
Researchers Observe Squeezed Light from Single Atom
Light is usually described as a wave, but at the most fundamental quantum level this wave consists of discrete particles called photons. A team at the Max Planck Institute of Quantum Optics, has now observed that the light emitted by a single atom may exhibit much richer dynamics. Strongly interacting with light inside a cavity, the atom modifies the wave-like properties of the … [Read more...]
Acoustic Cloaking Device Could Make Ships Invisible to Sonar
Scientists at Duke University in North Carolina have come up with a way to make objects invisible to sound waves, which could possibly lead to the development of ships that are undetectable by sonar. Described as an "invisibility cloak" for sound waves, the technique involves surrounding an object with several layers of plastic plates, each with holes in a specific pattern. The … [Read more...]
May 2011 Sales Growth for Semiconductor Industry
The Semiconductor Industry Association recently announced that worldwide sales of semiconductors were $25 billion for the month of May 2011, a 1.8 percent increase from the prior month when sales were $24.6 billion and a 1.3 percent growth from May 2010. All monthly sales numbers represent a three-month moving average. The industry continues to see demand for tablets and … [Read more...]
Offering of Thermistors Sample Kits Expanded
TDK-EPC is presenting three new sample kits of ceramic PTC thermistors from EPCOS. The components of the sample kit “SMD PTC Thermistors for Limit Temperature Sensing/Superior Series” are designed for use as temperature sensors. The kit contains samples for sizes 0402, 0603 and 0805 across the temperature range between 75 and 145 °C in steps of 10 K. All thermistors are … [Read more...]
Company Adds Family of Connectors to Inventory
Heilind Electronics has added Molex's new Flexi-Mate family of connectors to its inventory of connectors. Flexi-Mate connectors provide a full range of both board-to-board and wire-to-board solutions. Flexi-Mate connectors are designed for LED TVs and standard room-lighting applications that require the placement of LEDs on interconnecting panels across the full width of the … [Read more...]
IEC Releases New Connectors Standard
IEC 61076-2-106:2011 describes circular connectors with IP40 or IP65/67 protection degree, typically used for industrial process measurement and control. These connectors consist of fixed and free connectors, either rewireable or non-rewireable, with M16 x 0,75 screw-locking. Male connectors have round contacts Ø 1,5 mm or Ø 1,0 mm.Preview the standard. … [Read more...]
