Technical Information
Crimp Termination Assembly Instructions
A crimp connection is a non-detachable electrical connection between
a wire and a crimp contact produced with the crimp technology.
Precise crimping dies which are matched to the crimp barrel and the
wire size and a defined deformation result in a reliable electrical
connection.
There are open crimp barrels (stamped contacts) and closed crimp
barrels (turned contacts).
The main advantages of crimp connections are:
• Efficient termination of contacts
• Reproducible terminations achieve consistent electrical and
mechanical results
The requirements for crimp connections are defined
in IEC 60352 Part 2 / DIN EN 60352 Part 2.
An important point of the quality of a crimp connection is the
achieved tensile strength of the termination.
Easily measured, the tensile strength is a practible means for quality
control purposes.
Diagram 2 below shows the required minimum tensile strength for
open and closed barrels depending on the wire size
For crimp contacts use the released crimp tool.
The insertion and extraction of crimp contacts shall only be approved
with the corresponding insertion/extraction tool.
A detailed description of the crimp technology can be found in
our crimp tooling catalogues.
Crimp contacts are in this catalogue on page 20

Degree of Protection
Electrical devices to which connectors belong to have to be protected for
safety reasons from outside influences like dust, foreign objects, direct
contact, moisture and water. This protection is provided on industrial
connectors by its housings with their latching devices and sealed cable
entries. The degree of protection can be selected depending on the type of
intended use. The standard IEC 60529 and/or DIN EN 60529/VDE 0470
Part 1 has specified the degree of protection and divided into several classes.
The degree of protection is indicated in the following way:
