Encoders
Linear Actuators
Netzer Precision Position Sensors
(Misgav, Israel) introduced the
VLX-60 Electric Encoders™ that
feature an open frame, two-plate
design, and tolerance to temperature,
shock, EMI, RFI, and magnetic
fields. Features include a <10-mm profile,
hollow-shaft stator/rotor, no bearings
or other contact elements, digital interfaces for absolute position,
auto-calibration option, and output reading is the averaged outcome
of the entire area of the rotor. Output is digital serial synchronous with
absolute position single turn.

Motion and Automation System
PI, L.P. (Auburn, MA) offers
X-417 pre-configured motion
and automation systems including
EtherCat motion controllers
and software. The multi-axis mo -
tion subsystem features nano -
meter resolution and absolute
encoders for industrial precision
motion applications including
automation, test and inspection,
medical manufacturing, and semiconductor testing. The XY base system
is made of two 3-phase, motor-powered, V-417 linear stages with
travel ranges from 204 to 407 mm. The XYZ system includes an L-412
high-load linear stage mounted vertically, providing 4 " (102 mm) travel
range. The Z-stage is equipped with a synchronous servo motor and a
holding brake.

Quick Disconnect
Beswick Engineering (Greenland,
NH) offers the QDM34L series four-line,
dry break quick disconnect. The design
minimizes dead volume to eliminate
leakage when making or breaking connections.
Both the internal and external
ends include shutoff mechanisms that
remain fully closed during disconnection
and remain closed until completely connected.
They are equipped with a keyed
location pin and are available in 303 stainless steel. Each line has an
M3 threaded port for connecting fluid lines.

Slide Guides
NB Corp. (Hanover Park, IL) re -
leased SEBS-B type slide guides. All
stainless models are suitable for hightemperature
applications, cleanrooms,
and vacuum environments.
They are available in both retainedball
(whose elements allow for easier
handling since the guide block may
be removed from rail without ball
loss) or non-retained ball lines in sizes from 2 mm. Friction-free travel
ranges from 104 mm to 1,000 mm.

Cov
ToC
SureStep stepper motor linear
actuators from AutomationDirect
(Cumming, GA) are NEMA 17 or
NEMA 23 frame stepper motors
with a stainless-steel lead-screw ex -
tension of the rotor. In conjunction
with the provided screw nut, the
actuators translate motor torque
into linear thrust. They can provide up to 193 pounds of thrust or
speeds up to 18 in/sec. Eight standard leads (travel per rev) are
offered with screw lengths of 6 " , 9 " , or 12 " . Triangular screw nuts are
included.

Multiturn Encoders
POSITAL (Hamilton, NJ) introduced 22mm
multiturn kit encoders for miniature
motors and drives. The absolute position feedback
devices provide full multiturn measurement
capabilities without the need for backup
batteries. The rotation counter system is selfpowered,
so in the event of a power failure or
control system outage, the encoder's counter
circuits remain operational, maintaining a
record of any rotations that the motor drive shaft experiences. Once
power is restored, the motor's complete rotary position, including
rotation count, is forwarded to the central controller. Vendor-neutral
SSI and BiSS C communication interfaces are supported.

Digital Drives
Performance Motion Devices (West -
ford, MA) announced ION/CME NSeries
digital drives that provide
motion control, network connectivity,
and amplification. They feature
a rugged PCB-mountable package
with three power output levels of 75, 300,
and 1,000 Watts. All drives support brushless
DC, DC brush, and step motors. They provide profile
generation, servo compensation, stall detection, field-oriented control
(FOC), and electronic camming. They support Ethernet, CAN,
serial, and SPI communications.

Extrusion Head
Guill Tool & Engineering (West Warwick, RI) introduced
the 500 Series crosshead extrusion head with
mechanically assisted gum space adjustment.
It is designed for the flow characteristics
and processing challenges of elastomeric
compounds. The gum space adjustment
allows the operator to
make an adjustment from a single
point using a common socket
wrench. The visual indicator on
the core tube allows the operator to see how far the
gum space has been moved. A half rotation of the cam nut is
required to loosen and automatically extract the deflector from the
head body.
