■ Servo Drive
Advanced Motion Controls, Camarillo,
CA, has released a new servo drive capable of
outputting 50 A continuous current rms and
100 A peak current, providing the torque
necessary to drive motors in larger mobile
robots. The servo drive has a wide input voltage range of 20-90 DC,
allowing it to power mobile robots all day even as the battery levels drop.
Despite the drive's small size, it has a maximum continuous power output
of 4.5 kW. The mini-sized FlexPro® drives is said to outperform
larger-sized digital servo drives and still be integrated into tight spaces.
The PCB mount servo drive mates directly to the motor axis PCB, offering
tight and compact integration with the application.

■ Wi-Fi Modules
InnoPhase, San Diego, CA, has released
new Wi-Fi plus BLE5 modules. The Talaria
TWO™ INP1014 and INP1015 platform combines
wireless connectivity and an integrated
microcontroller for edge-of-network IoT
devices that require low power consumption
and a direct-to-cloud connection. A programmable, digital radio architecture
enables the INP1014/1015 modules to provide low power Wi-Fi connectivity.
The platforms include multi-protocol Wi-Fi and BLE5-long range
for wireless data transfer, an embedded Arm Cortex-M3 for system control
and user applications, and advanced security elements for device safeguards.
They can operate in stand-alone mode, in conjunction with an
external MCU, or in a hybrid mode.

■ Connectors and Terminals
Custom-fabricated electrical connectors and terminals
manufactured to OEM specifications have
been introduced by ETCO, Bradenton, FL. They
are suitable for a wide range of medical equipment
including diagnostic tools, mobility units, monitors,
and more. They offer discrete component overmolding
and are suppled on reels or loose for use
with various automation systems. Made from virtually any alloy and inlaid
or edge-laid with precious metals to achieve specific properties, they can
meet a wide range of medical equipment design requirements. Parts can
be produced in sizes from 0.008 to 0.090 in. thick with +0.002 in. tolerances,
depending upon materials and design requirements.

■ Cleaning Solvents
AGC Chemicals, Exton, PA, has developed
two new nonhazardous cleaning solvents.
AMOLEA™ AS-300 and AS-300AT are
based on new HCFO chemistry. The cleaning
solvents have an ozone depletion potential
of near zero and a global warming potential of less than one. They are
ideal replacements for HFC solvents, low boiling point HCFO solvents, as
well as n-propyl bromide (nPB or 1-BP) and trichloroethylene, which are
both undergoing risk evaluation under the TSCA. These new HCFO solvents
have a boiling point that enables low evaporation, which means less
solvent is consumed during the cleaning process. They also provide solvency
with Kb value of 44 and 118, respectively, and a favorable HSE
(health, safety, environment) profile.

■ Computer-on-Module
Review Display Systems Inc., Milwaukee,
WI, offers a new computer-on-module
designed to deliver scalable performance
for medical and other applications. The
Kontron COM Express Basic Type 7
computer-on-module is suitable for a
broad range of high-performance server applications. It offers up to 16
processor cores. Four optional SODIMM sockets provide up to 128 GB
DDR4 RAM of memory. Networking capabilities and connectivity are
supported with four 10 Gb Ethernet interfaces and up to 32 PCIe Gen
3 lanes. Two SATA ports are provided, with the option to integrate an
onboard NVMe if required.

■ CAD/CAM Software
Open Mind Technologies, Needham,
MA, has introduced its latest CAD/CAM
software suite with new and enhanced
features for NC programming in applications
ranging from 2.5D to 5-axis. The
hyperMILL® 2022.1 software includes a
new break-edge function for contour milling, combined pocket
milling, and a finish path, allowing cutter compensation and
increased efficiency for 3D plane machining. Automated 3D plane
machining strategy improves machining quality by searching for
high-performance path layouts according to parameters, including
when adaptive pockets are present. Tool data such as length, radius,
corner radius, and tool number and name can be transferred directly
from the software to a Heidenhain TNC640 control using the
hyperMILL® connected machining module.

■ PCB Assembly Adhesives
A line of light-cured adhesives specifically
designed for dam and fill applications is available
from EpoxySet, Woonsocket, RI. UV5400LV
is a low-viscosity, low CTE adhesive for
fill operation designed to provide high strength
to PCB materials. UV-8300T is a thixotropic,
damming material with very low CTE, and UV
5403S is a slightly thixotropic material that can be injected as a fill
adhesive, used as damming material, or used as a glob top. They are
specifically formulated to cure in 10 seconds with a bond line intensity
of 250 mW/cm2, 365 nm LED energy source.

■ Tool Setter
Renishaw, West Dundee, FL, has
released a noncontact tool setter that features
an ultra-compact design. The ex -
panded NC4+ Blue is now available in four
sizes, with operating gaps ranging from 55
to 240 mm. Measurement repeatability has also been improved across
the range, now down to ±0.5 µm on smaller separations. The systems
integrate blue laser technology and improved optics to improve tool
measurement accuracy. Compared to red laser sources, blue lasers
have a shorter wavelength resulting in optimized laser beam geometry,
which enables the measurement of very small tools and minimizes toolto-tool
measurement errors.
