to a higher voltage 5V supply for communication of strong
bus signals across 100 meters and longer distances. The
ISL3274xE transceivers are fully compliant with the EN
50081 and EN 50082-2 electromagnetic compatibility
(EMC) standards and the umbrella line-voltage standard
for information technology equipment (ITE) EN 61000.
“Our latest high-speed RS-485 isolated transceivers
radiate virtually no EMI, and they eliminate ground
loops between bus nodes to protect data transmission,”
said Philip Chesley, vice president of Industrial Analog
and Power products at Intersil. “The ISL32741E’s high
working voltage and ability to push its reinforced isolation
barrier up to 6kV enables customers to solve their most
difficult IIoT networking design problems.

Defined spacing between PCBs!
WR-BTB is a new family of signal plug connectors from
Würth Elektronik eiSos suitable for SMT assembly. The
plugs with coded guide are available in versions with
40, 64, 80 or 100 pins. The models with 0.8 and 1-mm
pitch are also available in various heights. Various
male and female plugs can be combined to achieve
precisely defined spacing between two boards through
the use of stable board-to-board connectors – so purely
mechanical spacers may not be necessary and could be
dispensed with, under certain circumstances.
WR-BTB connectors with 1-mm pitch are achievable
with a board spacing of 7.6 mm, 9.6 mm, 11.6 mm, 12.6
mm and 14.6 mm. The 0.8-mm pitch plugs allow even
more combination options for spacing from 4.9 mm to
15.9 mm. The high-grade connectors are specified for
operating temperatures from -55 to +85°C. The plugs
are available from Würth Elektronik eiSos from stock in
unlimited quantities and free samples can be requested.
