FLUID POWER: Bray Controls has expanded and improved its Series 52 2N1 ProxSensor line of valve status monitors to now include AS-I, DeviceNetTM and PROFIBUS® DP BUS network units with a solenoid drive, plus many other new features. Bray’s 2N1 ProxSensors combine two proximity sensors in one compact, self-contained and fully sealed enclosure. These valve status monitors deliver the rapid, bounce-free electronic valve signaling required for PLC, computer and solid-state circuitry used in process control and information networks. All units have a five-year warranty against material or workmanship defects. Bray’s new BUS Intelligent 2N1 ProxSensors offer all the features of the dc and ac units, plus network protocol/communication and remote access to valve position and diagnostics. These units contain two BUS-powered proximity sensors and applicable network pin and solenoid drive connections. The Series 52 is engineered to be impervious to vibration, moisture and most chemical and corrosive agents since all internal components are completely encapsulated with epoxy resin inside the rigid, fully sealed polymer enclosure. Multi-pin electrical connectors are weatherproof and provide quick-connect installation. Standardized factory pre-wiring prevents field wiring errors. The 2N1 ProxSensor mounts directly to Bray pneumatic actuators, eliminating contamination buildup between sensor and actuator.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
