AAM 33 M, high performance without bearings

AAM 33 M, In the world of encoders, the challenge is to develop increasingly technologically advanced and high-performance tools that are easy to install and integrate in various operational contexts. This spring, Eltra focused on the development of a new absolute multi-turn devicethat is modular, bearing-less and supplied in assembly kit form in order to make it extremely versatile and easy to install. This is exactly how the AAM 33 M encoder was born!

This encoder guarantees a high resolution (50 bits: 18 single-turn + 32 multi-turn) and a fast communication interface. Such features, combined with a wide range of operating temperatures(from -40 to +115° Celsius) and patented energy recovery system, make it particularly suitable for use in robotics,motor feedback and CNC applications. Three options are available for the electrical interface: SSI, BISS and RS485.

Who’s afraid of electrical discharges? We’re not!

In electronics industry production processes, electrostatic charges must be managed with great care. It is well-known that electrostatic can cause serious damage to products, so it is critical to create an environment that mitigates this risk in the best possible way. That’s why we decided to renew our production lines by equipping them with new Electro-Static Discharge (ESD) flooring, designed to dissipate electrostatic charges on its surface and those of items in contact, such as personnel, chairs, stools, and so on.

Of course, this comes without neglecting the standard flooring features demanded of a production line, with wear resistance, multi-hour walking comfort, and ease of cleaning guaranteed. However, for a company such as Eltra, which produces technological devices sensitive to variations in electrical voltage, conductivity, or the possibility to convey electrical charges to earth, is absolutely decisive. This means there is no risk of discharge, and our encoders are kept safe at all times throughout their production processes.




Robot window cleaners

Soon, images of brave, acrobatic window cleaners dangerously suspended high up on the side of metropolitan skyscrapers could be icons of the past. The Israeli start-up Skyline Robotics has developed a machine, called Ozmo, equipped with brush-ended, hyper-sensitive robotic arms that can clean the exterior glass of buildings just like human window washers. 

The sensors are designed to imitate the functions of a human hand, so that they are able to avoid all kinds of obstacle and therefore stop scrubbing rubbing or washing immediately in case, for example, someone leans out of a window. Each robot will boast a 3D map incorporated in its software describing the external surface of the building and all known protrusions and obstacles.

Finally, the washing process does not require soap or other detergents, but works via ‘reverse osmosis’, absorbing salts, minerals, oils, and building detritus. It is an important revolution also in terms of occupational safety, considering that, between 1983 and 2008, over 70 window cleaners fell and died during work.
