BREVA & BREVA S

Product catalog summary

Overview: The BREVA hexapod is a high-resolution, medium-sized positioning system designed for precision applications. It is available in two versions: the high amplitude BREVA and the compact BREVA S.

Key Features:

Payload capacity up to 200 kg.
Linear travel range of ± 75 mm and angular travel range of ± 22°.
Equipped with absolute encoders for precise positioning.

Applications: The hexapod is suitable for use in instrumentation, optics, testing laboratories, aeronautics and space, metrology, and synchrotrons. It is particularly useful for orienting microwave sources and aligning accelerator cell blocks.

Specifications:

Motion and Positioning: The BREVA offers a travel range of ± 75 mm (Tx, Ty) and ± 50 mm (Tz), with angular ranges of ± 20° (Rx, Ry) and ± 22° (Rz). The BREVA S offers slightly reduced ranges.
Resolution and Repeatability: Both versions have a resolution of 0.25 µm for linear movements and 1.5 µrad for angular movements, with repeatability of ± 0.5 µm and ± 2.5 µrad respectively.
Speed: Linear speeds of 6 mm/s (Tx, Ty) and 4 mm/s (Tz), with angular speeds of 1.5 deg/s (Rx, Ry) and 2.25 deg/s (Rz).

Mechanical Properties:

Constructed from aluminum, steel, stainless steel, and plastic.
Operating temperature range from 0 to +50°C.
Mobile platform sizes: Ø 310 mm for BREVA and Ø 289 mm for BREVA S.

Miscellaneous:

Options include clean room compatibility and a hand-held control unit.
Controller type is ALPHA+ with Ethernet interface, and power supply requirements are 110-240 VAC / 50-60 Hz.

Conclusion: The BREVA hexapod is a versatile and precise positioning system suitable for a wide range of high-precision applications, offering robust performance and adaptability.
