Robot Cell
Linear Encoder
The LoadMate Plus robot cell from Mitsubishi
Electric Automation (Vernon Hills, IL) can be easily
moved and is suited for manufacturers in CNC
machine tool applications. The robot cell automates
the task of loading and removing parts from
a machine tool through the use of robotics. It can
be mounted next to one machine, between two
machines, and otherwise moved around a facility
as required. When paired with an M8 Series CNC, operators can use
the Direct Robot Control (DRC) feature within the CNC controls to
control and program the robot with menus and G-code from the
same screen used for the machine tool. No robot programming experience
or teach pendant is required.

Servo Drive
The servSD from STXI Motion (Petach Tikva,
Israel) is a ready-to-connect, low-voltage servo drive
for applications such as automated guided ve -
hicles/autonomous mobile robots, electronics
assembly, and medical equipment. The drive doesn't
require pin soldering or cable adaptors; supports
common motor feedback types including SSI, incremental,
and BiSS; and uses real-time data exchange
for axis synchronization. The SD01-030 model offers a 24 VDC input
bus, 24 VDC input logic, continuous current of 30 Arms, and peak
current of 100 Arms; the SD01-025 model features a 48 VDC input
bus, 24 VDC input logic, continuous current of 25 Arms, and peak
current of 80 Arms.

Shaft Bushings
Zero-Max® (Plymouth, MN) offers Posi-Lok
shaft-hub locking bushings that eliminate the
need for keyways that can weaken or cause
excess wear to shaft components. They slide
onto a shaft for mounting and provide concentricity
with minimal radial and axial runout. The K Series is a single-taper,
flanged design available in four different models. The G
Series is a dual-taper flangeless design that supports shaft sizes from 19
mm to 120 mm. The D Series is a single-taper flangeless design for
smaller outside diameter and size for the connected component. The
M Series is a single-taper design with a stepped flange that provides a
self-centering feature in an alloy steel construction for shaft sizes from
20 mm to 50 mm.

MEMS Accelerometer
Silicon Designs (Kirkland, WA) offers
Model 2210 single-axis MEMS capacitive
accelerometer modules. They are available
in standard ranges from ±2 g to ±400 g and
incorporate a MEMS capacitive accelerometer
chip together with high-drive, low-impedance buffering. The modules
measure vibration and acceleration on either one, two, or three
orthogonal axes and generate two analog voltage outputs that vary in
response to applied acceleration. Output scale factor is independent
from the supply voltage of +8 to +32V. At zero acceleration, differential
output voltage is nominally 0 VDC; at full scale, it is ±4 VDC.

Cov
ToC
The LIKselect kit-style linear encoder from
HEIDENHAIN (Schaumburg, IL) is designed
for precise positioning within its control loop.
The miniature three-field scanning sensor is
offered with a variety of frame designs, allowing
the encoder to be integrated into complex machine system designs.
With selectable accuracies of ±3 μm/m or ±5 μm/m on a 20-μm pitch
scale, the encoder features a configurable scanning unit, measuring
steps down to 78.125 nm, electronic adjustment capability after mounting,
and standard incremental interfaces of 1 VPP, TTL, or RS-422.

Shock Absorbers
ACE Controls (Farmington Hills, MI) offers the
MC75 family of miniature shock absorbers for energy
damping in tight installation spaces in industrial manufacturing,
material handling, packaging, medical,
electronics, and robotics applications. They feature
energy capacity of 75 inch-pounds per cycle and
250,000 inch-pounds per hour. Available in weight
ranges from 0.5 to 2.5 pounds through 55 to 160
pounds, the units have length of 2.77 " . They also feature a 0.40 " stroke
length and one-piece outer body filled with temperature-stable oil.
Other features include continuous outer body thread with lock nut
and integrated positive stop.

Brushless DC Gearmotors
Brother International USA (Bridgewater, NJ)
offers brushless DC gearmotors that are lubricated
and sealed for life. The 12-48 VDC motors
are available with several shaft configurations
and custom options. They feature helical and
hypoid gearing, an e-coat finish for harsh environments,
and a power range from 50 to 400 Watts. They are suited for
applications in which brush dust contamination is to be avoided or
brush contact arcing could affect electronically sensitive equipment.

Transducers
AutomationDirect (Cumming, GA) released
Gefran WPG and WPP series magnetostrictive
linear position transducers that translate a linear
position to an electrical signal. They are
available in stroke lengths from 50 to 500 mm
and with an analog output signal of either 0-10 VDC or 4-20 mA for single-output
models. Double-output models provide either a 0-10 VDC
and reverse 10-0 VDC signal, or a 4-20 mA with a 20-4 mA reverse signal.

Hybrid Bearings
NKE Austria (Steyr, Austria) introduced hy -
brid bearings that consist of ultrapure steel bearing
rings and ceramic rolling elements made of
bearing-grade silicon nitride. The ceramic
rolling elements have high wear resistance for
demanding conditions such as poor lubrication. The rolling elements
are corrosion-resistant and high-rigidity. The raceway and roller geometry
have been designed for high load capacity.
