You dont install a telecommunications network every day.
It must therefore fulfil at least two criteria:
Interference-free functionality

Long-term reliability

You should not settle for less. ADC KRONE´s LSA-PLUS
®
technology is
precisely what you need to fulfil these requirements.
For decades, LSA-PLUS has been synonymous with
Security

Reliability

Quality

Economic efficiency

As a pioneer in quick connection techniques, ADC KRONE set the benchmark
more than 30 years ago with the invention of LSA-PLUS. Today, we are still
the technological front-runner when it comes to secure, quick and reliable
connections in telecommunications networks.
The continuous development of innovative applications with LSA-PLUS
technology ensures that you will be able to rely on a secure network with
original quality from ADC KRONE in the future too.
With these innovations, we enable telecommunications service providers
to introduce next-generation networks. We focus on the flexibility of the
networks, simple handling and cost effectiveness.
In more than 140 countries worldwide, the technically and
economically superior LSA-PLUS quick connection technique has
won over millions of users make up your own mind:
Unlimited transmission of all known communications services that use

shielded or unshielded two or four-wire copper cables as a medium
Connection of cable leads without soldering, wire-stripping or the use of

screws using a multi-functional sensor insertion tool
Patented contacts with optimum electrical conductance values

High contact reliability in the event of vibration, cold, heat, moisture and

other atmospheric or climatic influences
High wear resistance thanks to high-performance plastics

Compliance gas-tight contact points

Economical and user-friendly thanks to drastically reduced installation

times and maintenance intervals (low operating costs)
Compliance with ISO/IEC 352, Part 4

Certified production in accordance with ISO 9001 and ISO 14001

Fulfillment of additional environmental standards (such as RoHS)

Thanks to a consistent product policy and a high level of innovation,
ADC KRONE fulfils the requirements for a modern network topology
with an extensive product portfolio. This is rounded off by a broad
range of accessories.

Insulation Displacement technique from ADC KRONE
Connects leads without solder, screws or wire-stripping, which means that typical sources of interference in
these types of connections cannot occur. A correct insulation displacement connection prevents corrosion,
loosening caused by vibration, high-resistance joints and a weakening of the wires.

This technique forms the basis for the flexible networks of tomorrow. Page 5

contacts work according to the same basic principle, regardless of which connection modules are used.
How the ADC KRONE contact differs
The ADC KRONE 3-point insulation displacement contact guarantees a durable and reliable connection.

Positioning the contacts at a 45° angle only causes
a slight cross sectional change and therefore
no weakening of the stability of the connected
conductor.

Positioning the contacts at a 90° angle causes a
considerable reduction in the cross section, which
can lead to a possible wire break.
1. Clamping ribs fix the wire in position and protect the
contact points against vibration and other forms of
mechanical stress.
2. Flexible contacts in a special alloy, arranged at an
angle of 45° to the brace axis, form a gas-tight and
corrosion-resistant connection.
3. The constant torsion and axial reset forces of the
contacts inside the plastic casing ensure a long-lasting
connection.

PORTFOLIO
LSA-PLUS
®
stands for a technically and economically superior quick connection technique for all modern
communications networks. The LSA-PLUS connection technology ensures a high level of contact reliability
over decades even under the most difficult of environmental and climatic conditions.
The LSA-PLUS portfolio is continuously adjusted to the increasing requirements for telecommunications
networks in the 21st century.
Thanks to the comprehensive LSA-PLUS portfolio, an individual network tailored to special requirements can
be realised. Depending on the requirement, it is possible to choose between the LSA-PLUS NT, Series 10,
Series 2, Series 1 and HighBand
®
. The five series are outlined in detail below.

The LSA-PLUS
®
NT and Series 10
Characterised by the high connection density made possible by the compact and space-saving design.
The LSA-PLUS
®
HighBand
®
Optimised especially for use in high-speed IP networks.
The LSA-PLUS
®
Series 2
Characterised, among other things, by an extensive product spectrum and an extremely broad range of
accessories. It is popular around the world and has been tried and tested a million times over.
The LSA-PLUS
®
Series 1
Based on the idea of replacing solder lug strips with the insulation displacement technique. It is the oldest
of the series and was designed especially for flat mounting. Series 1 is intended for internal installation.

FEATURES AND FUNCTIONAL DESCRIPTION
The LSA-PLUS
®
series module casing is made of flame-retardant
thermoplastic polyester and is extremely resistant against
environmental influences (climate; aggressive atmosphere; exposure
to sunlight). The insulation displacement contacts arranged at an
angle in the casing are made of silver-plated special brass and are
characterised by their low transition resistances and their high
level of transmission quality, which is due not least to the gas-tight
insulation displacement connection. Naturally, LSA-PLUS technology
fulfils the high requirements of the standard ISO/IEC 352, Part 4.
Connection module
The functional principle of the LSA-PLUS connection module is
based on an unbreakable connection. On the system/cable side and
the jumper side, the cable leads are connected to the contacts
arranged opposite one another. In the centre are separate contacts
for each pair, which, for example, can be used for measurement
and testing work, for switching using switching adapters or for
inserting overvoltage protection magazines (3-point protection with
overvoltage protection contact arrestors or semiconductor elements).
The casing is grey.
Disconnection module
With the LSA-PLUS disconnection module, the connection can be
broken by placing a disconnection plug in the normally closed
contact between the connection contacts. Using patch and test cords,
it is possible to create a wide variety of different circuits for measuring and
testing. The disconnection module principle is particularly suitable for realising high-quality protection
concepts. The casing is white.
Switching module
With the LSA-PLUS switching module, the individual connection contacts and up to 40 idle circuits are
disconnected. By adding plugs or cords, circuits can be connected if necessary or used for measuring and
testing purposes. The installation of 5-point or graded protection is also possible. The casing is brown or,
in the LSA-PLUS NT modules, yellow.
Earth module
Depending on the design, the LSA-PLUS earth modules enable up to 84 cable leads to be laid to a common
electrical potential. Via a securely connected flexible earth line, the earth potential to a backmount frame or
to an earth terminal is established. The casing is red.
Mounting systems
ADC KRONE offers two mounting systems: the LSA PROFIL
®
fixing system and the LSA-PLUS backmount
frame system.
