65,536 steps per turn
( 16 bits).
■ Cycle times of <125
■ A distributed clock function to synchronize axes
within a microsecond.
■ Cable redundancy for improved
■ Availability with shaft and connector seals rated
at up to IP67 level and with explosion-proof
(ATEX certified) stainless steel housings.
Norgren AFP (Littleton, CO) has announced new gas-tight
analytical fittings and flexible sample stream selection valves.
The DVS Series sample stream selection diaphragm valves have
an independent port control, so stream selection can be automated to fit any process. The valves are also continuously swept, eliminating crossover between samples. The patented purge groove
eliminates cross contamination for better sample integrity and
improved analytical results.
Norgren AFP analytical fittings feature a patent-pending lip-seal
design. The gas-tight fittings can be installed using lower torque,
making them easier and faster to replace and reducing damage
PI's (Auburn, MA) P-763 XY
nanopositioning stage is a
new addition to PI's range
of piezo stage positioners.
The P-763.22C nanoposi-
tioning piezo stage is a multi-
layer-piezo-driven stage, providing
sub-nanometer resolution and rapid
response for fast step and settle or high speed scanning applica-
tions. With its capacitive feedback, linearity of motion is exceptional,
with only 0.02% deviation from a perfect straight line, when tested
on a laser interferometer. Features include:
■ A footprint of < 3" x 3" (70 x 70 mm).
■ A 30 x 30 mm aperture.
■ A travel range of 200 x 200 microns.
