UTG Series
One of the key factors which affects the performance of a connec-
tor, is the way contacts are terminated. Crimped connections are
nowadays seen as the best solution to ensure quality throughout the
lifetime of the product. Here are some reasons why we recommend
this method of termination for UTG connectors:
Advantages (Extract from the IEC 60352-2):
- Effi cient processing of connections at each production level
- Processing by fully-automatic or semi- automatic crimping
machines, or with hand operated tools
- No cold-soldered joints
- No degradation of the spring characteristic of female contacts
by the soldering temperature
- No health risk from heavy metal and fl ux steam
- Preservation of conductor fl exibility behind the crimped
connection
- No burnt, discolored and overheated wire insulation
- Good connections with reproducible electrical and mechanical
performances
- Easy production control.
To ensure that the crimp tooling is performing according tooriginal
specifi cations, it is important to carry out regular checks. A com-
mon way to check the performance of tooling is with a simple pull
test, ideally using a dedicated electric pull tester. Minimum recom-
mended full forces are indicated in the tables below:
