PI Launches Compact Precision Motorized Translation Stages
Auburn, MA — The L-408 linear stage from PI strikes a good balance of load capacity, precision and cost. It has applications in research and industry, including optics, biotech and assembly of miniature components and photon- ics instrumentation. The new, compact, x-axis linear
stage provides precise motion and reliability with anti-creep, crossed roller bearings. Driven by a high-res- olution leadscrew with 0.02 in. (0.5 mm) pitch, minimum incremental motion of 100 nm is achieved over a travel range of 1 in. (25 mm). Despite its compact size, the stage can han- dle payloads of up to 44 lb (200 N)
EOS Power: Ultra-Flat Versatile Power Supplies
Highland Village, TX — EOS Power is now offering its VPS600/1000 series of medical and commercial, high-efficiency AC/DC products. The company’s top-selling series for embedded solutions, the WLC550 and the ultra-flat ULP series from 25 to 275W, are all based on standard footprints. Key advantages of EOS products include options to modify the standard offerings and provide value-added solutions.
and provides a push/pull force of 11 lb (50 N). Stepper and servo motors
are offered with direct-drive and gearbox options. The maximum
velocity of the direct-drive stage is 0.4 in./s (10 mm/s). The unidirection- al repeatability of all versions is 0.02 mil (0.5 µm). High-resolution, motor- mounted optical encoders provide position feedback to the motion con- troller for closed-loop operation. Non- contact, optical limit switches and reference point switches with direc- tion sensing in the middle of the travel range simplify use in automa-
tion applications. Contact: PI (Physik

Flat, stacked ULP series power supplies.
The VPS series is the first group
of EOS products entering the midsize output segment above 600W. The power supplies are less than 1U flat and deliver 600 to 1,000W, depend- ing on the cooling options selected. The WLC series offers up to
250W, conduction-cooled, and up to 550W with forced air, depending on cooling options and due to its double- plate thermal spreading technology. Both VPS and WLC can be operated in parallel mode and offer multiple mounting, cooling and modification options. The ULP series offers high
power density — up to 30W per cubic inch, with maximum height profiles of 0.75 in. (19 mm). The (M)ULP40 180 and 275W series offer customers the possibility of using standard 2 x 4 and 3 x 5 in. (5 x 10.2 and 7.6 x 12.7 cm) open-frame, medical- and commercial- grade power solutions in height- restricted environments, with out hav- ing to change mechanical footprints to
increase efficiencies. Contact: EOS Power US, 790
