The new sensors of the compact series in M30 design have a reduced blind zone and are shorter than models of the previous generation. These improvements make for better detection of objects at close range and reduce the space requirements of the components. The new programming interface lets users read out status and diagnostic information in running operation without any reaction. This means you can easily adapt the parameters to the operating environment for process optimization.
The space requirement of a sonar proximity switch in a machine or plant is mainly determined by its blind zone. The switch must be installed at a location that is set back by the length of the blind zone from the detection range to ensure reliable detection of the close-up range. This so-called dead space is reduced by more than 50 percent for the latest generation of Simatic PXS sonar proximity switches – space available to reduce the size of the machine or plant. The extremely narrow sonic lobe and the improved noise suppression make for object detection even under difficult environmental conditions and will thus increase machine availability.The reactionless transmission of sensor data in measurement operation makes for exact setting of parameters to the application. The result is an increased quality of the sensor signal. The sensors in M30 design are available for four different detection ranges up to six meters. The K1 version has one switching output; the K2 version has two. K3 is available in several versions: with one switching and one analog output, with one IO-Link channel or Atex certification for operation in Ex-Zone 2/22. Versions with rotary head or recessed converter are available for K2 and K3 sensors.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
