savings over similar aluminum devices. TE’s DEUTSCH
group created one of the original composites in 1990,
and its ACT series shells are not only very lightweight,
they are also highly resistant to corrosion, withstanding
2000 hours of salt spray, and very durable, surviving
1,500 mating cycles.
ACT series circular connectors are among the most
versatile and popular circular mil spec input/output
connectors in the world. They are available in three shell
styles, two plating options, six shell clockings, over 50
different insert arrangements supporting size 23, 22D,
20, 16, 12, 10, and 8 contacts for power and signal, as
well as coax and twinax contacts.
Originally designed as military and aerospace
components, ACT series connectors are now also
used in many other hi-rel applications where extreme
reliability is paramount. They feature a scoop-proof
design for fast, easy, secure mating, and a triple-lead,
threaded self-locking coupling for excellent vibration
resistance. Devices are environmentally-sealed and
feature grounding fingers and a trapezoidal thread
which provides excellent shell-to-shell continuity, to help
support high EMC performance.
Comments Alec Sluce, Aerco’s Connector Product
Manager: “These lightweight, rugged, environmentally-
sealed connectors survive some of the harshest
environments of commercial and military aerospace,
ground defence, and marine applications. TE’s
DEUTSCH composite connectors have led the field in
composite connectors for many years, and this latest
generation ACT series reinforces their reputation for
high quality, extreme reliability and ease-of-use.”

Intersil Introduces High-Speed RS-485
Transceivers with Highest Reinforced Isolation
Intersil, a subsidiary of Renesas Electronics Corporation
(TSE: 6723), today announced two new high-speed,
isolated RS-485 differential bus transceivers that provide
40Mbps bidirectional data communication for Industrial
Internet of Things (IIoT) networks. The ISL32741E offers
1,000VRMS working voltage and 6kV of reinforced
isolation, more than 2x higher than competitive solutions.
The higher working voltage and reinforced isolation is
required for today’s most rigorous medical and high-
speed motor control applications. The ISL32740E with
2.5kV of isolation and 600VRMS working voltage comes
in the industry’s smallest package, enabling high channel
density for programmable logic controllers (PLCs) in
factory automation applications.
The ISL3274xE transceivers provide additional
advantages over other isolation technologies, including
ultra-low radiated emission and EMI susceptibility,
support for up to 160 devices on the bus, and an extended
125°C temperature range. These devices leverage giant
magnetoresistance (GMR) technology that provides
galvanic isolation to keep the communication bus free
from common-mode noise generated in electrically
noisy factory and building automation environments.
In addition, Intersil’s GMR isolation does not require
the elaborate encoding schemes found in capacitive
and transformer-based isolators that use RF carriers or
pulse-width modulation (PWM) to transfer DC and low
frequency signals across the barrier.
The ISL3274xE transceivers are ideally suited for the
equipment-to-bus interface in PROFIBUS DP and
high-speed RS-485 networks that connect PLCs to
instruments, robots, motor control drives, as well as
data acquisition and digital I/O modules. In addition to
not requiring any shielding, these transceivers simplify
PCB layout, use less board space, and enhance data
transmission reliability and integrity. The ISL3274xE
devices also offer low power consumption. For example,
the ISL32740EIAZ’s 60mA supply current allows it to
operate in a tiny 4mm x 5mmQSOP package at maximum
speed without overheating.
On the non-isolated control-side, the ISL3274xE
transceivers support direct connection to a 3V
microcontroller(MCU)whiletheisolatedbus-sideconnects
