ELECTRONICS
High-voltage connectors
Parker Hannifin (Cary, North Carolina) launched three new
thermally conductive gap fillers designed for EV battery systems.
The CoolTherm SC-2000 RW reworkable gap filler is a
soft-curing, low-density and low-abrasion silicone gap filler
that reportedly offers excellent thermal conductivity. Parker
Hannifin states that the CoolTherm SC-2000 RW was designed
with rework in mind and maintains flexibility during
battery manufacturing and end-of-life disassembly. Also announced
was the CoolTherm SC-3000 LD, a low-density, twocomponent
silicone that provides high thermal and shock resistance,
and the CoolTherm UR-2000, a two-component
thermally conductive urethane system that cures at room
temperature and adheres to powder-coated and e-coated
aluminum surfaces, such as battery boxes and cooling plates.

Heat-resistant plastics
Polyplastics Group (Tokyo,
Japan) announced a new
heat-resistant plastic for
EV cooling components.
Polyplastics states that
general-purpose engineering
plastics like polyoxymethylene
(POM) or polypropylene
(PP) can be
used instead of metals or high-performance EV plastics. The
company utilizes PP-LGF (long-glass fiber) instead of short
glass fibers to increase strength, dimensional accuracy and
overall performance. Polyplastics also offers DURACON bGPOM
made with biomass as an eco-friendly option. The company
claims that replacing high heat-resistant plastics such as
PPS with POM and PP not only reduces material costs but also
helps with efforts to reduce CO2 by reducing the carbon footprint
of materials and energy consumption during molding.

AUTOMOTIVE ENGINEERING
TE Connectivity (Schaffhausen, Switzerland) released its
HVA HD400 high-voltage connectors that are IP68 and
IP6K9K rated and have been designed to withstand transmission-level
vibrations. The company states that its contact
position assurance (CPA) ensures a secured contact
between the female and male connector during the mating
process. The HVA HD400 high-voltage connectors are
rated for up to 1,000 VDC, and 60 A (at 80 deg C/176 deg
F) and have an operating temperature of -40 to +140 deg
C (-40 to +284 deg F). Their design reportedly allows for
either 2 or 3 conductors in the same interface, handling
2.5, 4 and 6 mm² LV216 conductor cross-sections singlecore
cabling (multi-core and ISO cabling on the way).

Microwave switches
Pickering Interfaces
(Essex, United Kingdom)
announced a new 40/42890
family of modular,
flexible PXI/PXIe microwave
switches. Pickering
states that they are suitable
for test environments
requiring high-frequency
microwave switching such as from radar, satellite and shortrange
land-based secure communications to consumer electronics
and 5G infrastructure. The new 40/42-890 microwave
switch family reportedly provides a configurable RF switching
solution up to 110 GHz via the PXI platform, delivering flexibility,
versatility and test system optimization. A full range of
SPDT, SPnT, and transfer switch types are offered in PXI/PXIe,
with terminated or unterminated ports at frequencies up to
110 GHz with options available in 50Ω or 75Ω impedance.
