What is a moving coil actuator?
In this, the first of several technical notes on moving coil actuators, Ed Neff, President of SMAC Moving Coil Actuators (MCA), provides a brief history of linear actuators and explains where moving coil actuators fit in.
IO-Link as the key to implementing Industry 4.0
IO-Link was originally developed in order to provide easy standardized wiring of intelligent, complex sensors and actuators using a simple three-core sensor cable. As the issues surrounding Industry 4.0 grew more specific, it quickly became clear that IO-Link is the key in implementing powerful Industry 4.0 concepts, since a wide variety of field information is required from production plants.
Are you prepared for OT security?
In today’s connected world, with the Industrial Internet of Things and increased adoption of industry 4.0, businesses must deal with more and more connected devices. Security is key to success here and should not be ignored, says Tim Ricketts, Director of M.A.C. Solutions.
What is the difference between full ceramic and hybrid bearings?
Approximately 27,000 ceramic tiles cover the exterior of the NASA Space Shuttle – a reusable spacecraft that carried astronauts in a low orbit around Earth. Acting as a thermal barrier to the 1650degC generated by atmospheric re-entry, the tiles illustrate the impressive resistance of ceramic materials. The impressive properties of ceramics are also being used in bearings. Here, Chris Johnson, managing director of precision bearing specialist SMB Bearings, explains the specifications, capabilities and differences of full ceramic and hybrid bearings.
Root cause analysis aids development of new bearing materials
The symptoms of bearing damage known as White Structure Flaking, which occur in wind turbines as well as other drive systems, typically become noticeable very early, well before the end of the bearing’s expected service life. The causes have long remained unknown, but now, new findings are being made available by NSK, the results of which have led to the development of a new bearing material that offers significant benefits for wind turbine longevity.
Choosing the right filter for a measurement application
When selecting sensors for displacement, position, distance and profile measurement tasks, engineers should consider the various types of sensor filtering before making a purchasing decision, says Chris Jones of Micro-Epsilon.
Now is the time to improve cabinet cooling before next summer
Karl Lycett, Rittal UK's Product Manager for Climate Control, says that anyone who experienced overheating control panels last summer should make a New Year's Resolution to improve cooling in case 2019 brings another heat wave. A good starting point would be a free Cooling Review.
Human–robot collaboration and the use of AI: trends in packaging
Malte Schlüter, Global Key Account Director F&B/CPG at Mitsubishi Electric, presents four trends that are currently influencing the packaging industry and will go on to shape the future.
