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).

POWER SOLUTIONS AT PCIM 2017

Magnetic Components based on Adaptive CCM Technology Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204). The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Component materials meet UL 94-V0 rating. Cost-effective Common-mode Chokes Qualified for Aerospace Exxelia designed this extensive and cost-effective range to be an easy commercial (COTS) solution for aerospace, defense, and other high-reliability applications. The TCM series is available in a through-hole package for horizontal or vertical mounting. TCM chokes are offered with inductances from 0.7 mH to 47 mH under rated currents from 0.3 to 4.0 A. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Excellent thermal properties allow the series to operate from -55° C to +125° C. The high mechanical performance of the component materials (all meeting to UL94 V0 rating) makes TCM a perfect fit for aviation, defense and transportation industries.
