New extended Harwin
Spring Contact Connector
range now includes 13 types
in extended C and Positive
Stop styles, plus low profile
1.1mm model
Ideal for low voltage connections
and grounding to prevent RFI/EMI;
suits antenna feeds in wearable and
mobile applications
Portsmouth, UK, 10 November
2015… Harwin, the leading hi-
rel connector and SMT board
hardware manufacturer, announces
a significant extension to its popular
Spring Contact Connector range,
with thirteen new models offering
design engineers more options
to select the best design for each
application. The new range includes
extended C and Positive Stop
models in nine different heights,
ranging from 4.5mm down to low
profile designs a mere 1.1mm
above board level, enabling smaller,
lighter, low-profile PCB designs to be
achieved. Harwin Spring Contact
interconnects suit a wide variety of
applications and markets, including
antenna contacts in wearable and
mobile applications, RFI screening,
LED lamp connections, RF ID tags,
vision systems, PCB grounding and
board-to-board contact.
Harwin Spring Contact connectors
maintain a positive force against a
mating surface and are available in
different widths to offer a choice of
spring contact forces. Tolerant to
significant mating misalignment, the
new design incorporates “positive
stop” to prevent damage caused by
over compression. A contact anti
hook up feature is a further benefit.
Specifications include gold-plated
contacts and current rating up to
1.0A. Reliable and durable, Harwin
Spring Contacts can withstand up to
10,000 mating cycles and operate
over a temperature range of -40 to
+85 degrees Celsius. Supplied on
tape and reel, the Spring Contact
Connector range enables low-cost
assembly with automatic pick and
place machines.

Product
Manager, Graham Cunningham,
“The extended Spring Contact range
builds on an already enormously
popular product line and now
brings even wider choice to design
engineers. Today, the pressure is
on to fit ever more functionality into
less space, and our ultra-low profile
1.1mm Spring Contact in particular
helps designers meet “smaller and
lighter” demands.”
ERNI Electronics
Introduces Optimized High-
Speed Connectors
Introducing the new ERmet ZDpro
connector family, ERNI Electronic
paves the way to 100G ATCA
systems. The ERmet ZDpro
connectors are an enhancement
of the ERmet ZD family. This high-
speed differential Hard Metric
connector system enables data
rates of >25 Gbit/s and is the first
connector system that meets the
requirements for 100G ATCA
technology. The high data rates and
the improved transmission behavior
are mainly based on the reduced
size of the signal termination,
designed for vias with a diameter
of only 0.30mm. The drilling hole
diameter for the shielding contacts
is specified with 0.46mm. The fact
that the reduction of the vias leads
to an improved crosstalk behavior
was the motivation to the further
miniaturization of the press-fit zone.
The communication technology
showsanongoing trend to increasing
data rates and higher bandwidths.
Theas means there is a strong need
for 100 Gigabit Ethernet (GbE) data
transmission. Typical applications
are the next generation of internet
backbones, data centers or cloud
computing. The new ERmet ZDpro
connectors fulfill the requirements
and challenges of the important
interface between backplane and
daughter cards in these high speed
systems.
The ERmet ZDpro is based on the
mechanical design of the proven
ERmet ZD and ERmet ZDplus
with the same dimensions. ERmet
ZDpro connectors are backwards
mating compatible to ERmet ZD and
ZDplus connectors. This means,
that existing backplane designs do
not need layout changes on the
backplane side, if customers want
to upgrade their daughter cards
in the first step before upgrading
the whole system. Of course the
layout on the daughter cards has
to be modified, if ERmet ZDpro
