Exxelia à Eurosatory

Du 11 au 15 juin, dans le hall 5A stand E543, Exxelia présentera ses dernières solutions électromécaniques comprenant des codeurs optiques absolus.

Codeurs optiques absolus

Exxelia possède une grande expertise dans la fabrication de capteurs de position : codeurs absolus miniatures, codeurs incrémentaux, codeurs rotatifs, technologie magnétique et capteurs inductifs. Plusieurs gammes de codeurs optiques absolus seront présentées sur stand d’Exxelia - Hall 5A stand E543. Les codeurs optiques absolus sont des capteurs de position qui utilisent des signaux optiques pour identifier une position angulaire absolue. Les gammes de codeurs optiques Exxelia offrent de très hauts niveaux de performance pour un très faible encombrement : haute précision (<30arcsc.), haute résolution (jusqu'à 21 bits), faible épaisseur (10mm) et compatibilité EMI EMC. Ces codeurs miniatures sont adaptés aux marchés de l'aéronautique, défense et médical. Différents protocoles sont disponibles pour correspondre à tous les types d'application. 

Deux nouvelles gammes de condensateurs  MIL39006/22 & MIL39006/25

Exxelia a introduit deux nouvelles gammes de condensateurs tantale gélifiés ayant obtenu la qualification MIL-PRF-39006 de niveau M (1.0% / 1000h) : MIL 39006/22 & MIL 39006/25. Ces deux gammes, respectivement équivalentes aux modèles CLR79 et CLR81, associent compacité, fort courant efficace et faible courant de fuite. Conçus avec un boîtier tantale cylindrique hermétique avec terminaisons axiales, les produits MIL 39006/22 & MIL 39006/25 sont proposés dans des tailles de boîtier standards de T1 à T4 avec des plages de capacitance et de tension étendues.
La gamme MIL 39006/22 est qualifiée pour des tensions de 6V à 125V, avec des capacités allant de 1200µF @ 6V  à 56 µF @ 125V. La gamme MIL 39006/25 est quant à elle qualifiée pour des tensions de 25V à 125V avec des capacités allant de 680µF @ 25V à 82 µF @ 125V. Ces deux gammes combinent une grande capacité de stockage d’énergie avec une plage étendue de température de fonctionnement de -55°C à 125°C, ainsi qu’une très bonne tenue aux chocs et vibrations (option H disponible).

Exxelia onboard Solar Orbiter

Solar Orbiter, a European Space Agency mission, was launched on an Atlas V rocket 411 (AV-087) from Space Launch Complex 41 at Cape Canaveral Air Force Station at 11:03 p.m. EST on Sunday, Feb. 9 2020. The satellite reached its first working orbit around the Sun, called “halo orbit” and is ready to begin its first scientific observation campaign. The campaign will last six months, during which time the 55 payloads will be turned on one by one and tested before being used to perform scientific observations. Solar Orbiter is a highly complex scientific laboratory. Deploying such a mission is a one-of-a-kind achievement! The mission will take years and is one of the most highly anticipated scientific experiments of our time. And you know what they say: your best work comes when you&#39;re up against the toughest challenges. Unfortunately, these challenges aren&#39;t only in labs, but also in space. To study the Sun and its activity like never before, scientists are sending a probe into orbit around it. Solar Orbiter will be facing temperatures of up to 500°C, which is usually not survivable for complex equipment. But do you know what&#39;s even more challenging than getting data from a 500°C hot solar environment? Getting that data with expensive equipment that doesn&#39;t work, because you don&#39;t have enough reliable components at your disposal! That&#39;s why we, at Exxelia, were so happy when we heard that thousands of our capacitors and magnetics were chosen by the European Space Agency to achieve this mission; we&#39;re talking about components that will keep working in those kinds of harsh environments! They will help scientists better understand energy flow and particle acceleration within our own solar system and beyond. Shockingly, the Sun is mostly a mystery. We have some understanding of its composition, but it&#39;s unclear how the phenomena we see happen. Solar Orbiter is going to help us get a better idea of what makes the Sun tick by taking some of the most detailed images and observations of our star ever taken. Among the instruments on Solar Orbiter are: a Wide-Angle Imager and a Coronal Imager. Each will provide high-resolution images—an order of magnitude higher than those captured by NASA&#39;s Solar Dynamics Observatory—and spectacular views of the Sun&#39;s polar regions. The Wide-Angle Imager will capture images in five wavelengths, while the Coronal Imager will use seven wavelengths to observe phenomena that affect the upper layers of the solar atmosphere, such as magnetic fields and plasma flows. Our capacitors and magnetics are critical for stabilizing and powering these instruments on their mission to explore our home star! They need to be able to perform in a very hostile environment with temperatures ranging from -150°C (-238°F) to 500°C (932°F). Temperatures will reach their highest during the closest flybys of the Sun—which will take place as close as 15 million kilometers (about 93 million miles) from its surface. Our space capacitors and magnetics are capable of withstanding such high temperatures. They&#39;ll even keep functioning in cryogenic conditions, as low as -150°C (-238°F). These components are also very durable, which makes them perfectly suited for this mission.     Choosing the right capacitors for such a mission was not easy. The requirements and technical constraints were very strict. We had also to support and select the materials that could handle the launch vibrations and the shock of the rocket launching phase, we also had to achieve a very long life and high reliability in order to succeed in the mission. This project proves that our EXXELIA components are incredibly reliable and have nothing to envy to other electronic components on the market. Several other tests have been conducted by ESA in this project such as solar radiation, thermal shock...

Exxelia will integrate a cobot into its manufacturing process

Exxelia has just equipped itself with a cobot (in partnership with the company Cognitive Engines) adapted to the production needs related to the manufacture of RF High Q capacitors. The cobot is a collaborative robot designed to work hand-in-hand with operators. This technology coupled with artificial intelligence (I.A) offers a multitude of advantages including:   Quality improvement: The cobots are equipped with high performance sensors and integrated quality control systems, which allow 100% thorough visual inspection, and guarantee a high level of quality, while adapting to the movements of the operators (no occupational safety risk). Flexibility: Cobots are lightweight and adaptable. This versatility allows them to occupy different positions depending on the needs of the moment. Safety: Cobots are designed to be used in pairs with Exxelia operators and can therefore protect them from dangerous or arduous tasks, which greatly improves the quality of life at work (reduction of repetitive gestures; positive impact on musculoskeletal disorders ). Optimization of operator time: Cobots take care of low value-added tasks and let the operator focus on high-value tasks, which values ​​the contribution of operators.     By collaborating with operators, cobots can improve production quality and accuracy, while ensuring their safety. Industry 4.0 is changing the way businesses operate and the way products are designed, manufactured and delivered. Exxelia is convinced of the importance of Industry 4.0 and is positioning itself to be at the forefront of this transformation.           As a company specializing in the design and manufacture of critical electronic components for industrial applications, Exxelia pays particular attention to maintaining its extensive know-how. Exxelia uses state-of-the-art technologies to ensure the high level of quality that the applications the group serves cannot be without. The group pays particular attention to the coexistence of robotization with the mastery of manual processes held by operators to continue to offer customers the highest quality products, while remaining competitive. Adopting this technology will allow Exxelia to maintain its leadership position in its industry, while improving quality, accuracy, operator safety and production efficiency.
