Detecting those faults
In the wire and cable industry there are a number of demanding sensor
applications which require the detection of joints and faults in order to automate
additional process steps. Roland Electronic has developed a new eddy current-
based system for these detection applications.
Examples of such sensor applications are:
detection of broken leads in extruded cables
detection of cable connections after the extruder
detection of the joint between a heating cable and a connecting cable
detection of butt welds in wires
detection of mechanical connections in continuously processed automotive
gas tubes
The third example in the above list is an especially demanding task because of the
process speeds and the precision with which the connection between heating
cable and connecting cable
must be detected.
For this purpose the cable is
guided through the sensor
orifice for printing and marking
the joint with a black stripe.
In a separate process step the
cable is cut off precisely at the
joint between heating cable
and the connection cable.
The PC-based eddy current Weld Seam Detector SND
40 with the custom designed sensor STW functions
very well for these applications. The system replaces
an older analogue sensing system.

Due to the recent appearance of bundled cables in the EIA/TIA 568A standard, together
with the 10GBASE-T specification, Aesa Cortailloid decided to launch a new measuring
system – the Vega 1028 – to cover all testing requirements.
The Vega 1028 is a high quality instrument with state-of-the-art measurement
technology, which is fast, reliable and very accurate. It is delivered with a high end
computer system. The tester can be equipped with a full range of software and
hardware options to fulfil all possible requirements coming from customers.
This tester has been especially developed to answer the rising demand of LAN cable
manufacturers in testing cables according to the latest European and American
Standards for Category 5, 5E, 6, 6A, 7 and 7A cables. This statement is valid for 4 pair
cables but also for bundled cables up to 28 pairs.
The latest standards for bundled cables require ‘Alien’ crosstalk parameters to be
tested. These measurements are quite time consuming if they cannot be performed
automatically, due to the high number of required test commutations as well as the
terminations for the pairs not under test. The Vega 1028 tester fulfills the ‘Alien’ test
requirements fully automatically.
The switching technology, integrated by Aesa in its new Vega 1028 measuring system,
which has proven its capabilities over the past years, brings an accurate, efficient
and fast solution to the actual existing testing problems. Moreover, the flexibility
of the latest generation software allows using the connecting frames in all possible
configurations.
