NEW INVAR TUNING ELEMENTS WITH SELF-LOCKING SYSTEM
Exxelia announces the release of new world-unique invar tuning elements featuring a self-locking system. The product has been designed to respond to increasing demand for high frequency tuning elements for space applications.
Working frequencies in Space applications are shifting to Ka, Ku or even Q band, while cavity filters are undergoing the general trend towards miniaturization: this context calls for a much more precise and stable tuning element now offered by Exxelia Temex, daughter company of Exxelia, through their last innovative and unrivalled solution to incorporate a self-locking system into their Invar Tuning Elements.
Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.

State-of-the art absolute optical encoders Exxelia has acquired deep expertise in the development of contactless position sensors of several type: absolute and incremental optical encoders, magnetic technology and inductive sensors. Several ranges of state-of-the-art absolute optical encoders will be showcased at the company booth - Hall 5A booth# E543. Absolute optical encoders are position sensors that use optical signals to identify an absolute angular position. They provide the highest resolution, operating speed reliability as well as long life operation in most demanding environments. Exxelia ranges of absolute optical encoders offer very high performance levels for a very small footprint: high precision (<30arcsc.), high resolution (up to 21 bits), extreme thinness (10mm) and EMI EMC compatibility. With their compact design, Exxelia miniature encoders meet the requirements of the most demanding application such as aerospace, defense, medical, oil & mining industries. Various protocols are available to match with any application. Exxelia encoders can be easily combined with other functions such as slip rings to provide customers turkey solutions. Two new ranges of MIL-qualified wet tantalum capacitors: MIL39006/22 & MIL39006/25 The recently introduced ranges of MIL-qualified tantalum capacitors will be showcased on the company booth. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types featuring hermetically sealed cylindrical tantalum cases and axial leads are available in T1, T2 T3 and T4 cases with extended capacitance and voltage ratings. MIL 39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @6V to 56µF @125V. MIL 39006/25 is qualified for voltages from 25V to 125V and delivers from 680µF @25V to 82µF @125V. Both ranges combine high energy density with a large operating temperature range of -55°C - +125°C and H vibrations and shocks resistance.
Exxelia acquires Deyoung MFG., INC.
“The DMI acquisition directly supports our Magnetics SBU expansion strategy. DMI’s strategic location in the Pacific Northwest aerospace market provides a key geographic location for driving growth and profitability,” said François Vignaud, Exxelia Magnetics’ SBU VP. “DMI is highly regarded for the quality of its products and the operational performance of its organization.
