ELECTRONICS: Omron Scientific Technologies Inc.’s G9SX-LM Low-speed Safety Monitoring Unit consists of two proximity sensors and a G9SX safety controller with fault diagnostics, the G9SX-LM is a Category 3 (EN954-1), SIL 3 (IEC/EN 62061) certified redundant safety system that monitors and confirms motor rotation speed to facilitate safe machine maintenance. The system can also provide standstill monitoring.The G9SX-LM allows an operator to access the machine for maintenance work while the machine is running at a safe, maximum set operating threshold of 10 Hz. Should the motor speed exceed the preset speed, the G9SX-LM will stop the machine immediately. An optional A4EG Enabling Grip Switch provides an additional layer of safety protection that, if pressed or released, will also immediately stop the machine.
The G9SX-LM is certified to all relevant North American and International safety standards and is engineered to deliver reliable standstill and low-speed monitoring operation for machine tools, printing presses and other applications. The system is suitable for use with servomotors.
The G9SX-LM is rated for 24V dc operation, and is available with spring-cage or screw terminal blocks. It has eight semiconductor outputs - two instantaneous safety outputs, two safety slow-speed/stopping detection outputs, and four auxiliary outputs. Detailed LED indicators provide easy-to-read and understand diagnostics.
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.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
