■Tools
The tools specified by Hirose should be used for crimping work.
Crimping work by tools other than those specified must not be done because it may result in contact failure,
disconnection of cable, etc.
* The operating instructions manual is available for the crimping machine and the applicator.
Be sure to carefully read the operating instructions manual before implementing the work.
■Applicable Electric Wires
Check that the electric wire to be used is within the applicable range.
If you intend to use an electric wire other than those recommended, ask a HRS sales personnel.
[ Precautions]
・Electric wires that are suitable for crimping connectors are tin- plated stranded softcopper wire.
・Avoid crimping solid wires, wires with polyester threads or tin- coated wires.
・Avoid crimping two electric wires together.
・The crimp height setting value ( Note) may vary between tin- plated and gold- plated contacts even if the
same electric wires are used.
・The crimp height setting value ( Note) may vary depending on the difference in the core wire configuration even if the
computed cross- sectional area is the same.
Note : The crimp height is an important item that determines crimping quality. We execute crimping tests for
each electric wire to ensure the optimal value for the crimp height with high precision, thereby ensuring
optimal setup values.

While Taking into Consideration
Specifications mentioned in this catalog are reference values.
When considering to order or use this product, please confirm the Drawing and Product Specifications sheets.
Use an appropriate cable when using the connector in combination with cables.
If considering usage of a non- specified cable, please contact your sales representative.
If assembly process is done by jigs & tools which are not identified by Hirose, assurance will not be given.
If considering usage for below mentioned applications, please contact your sales representative.
In cases where the application will demand a high level of reliability, such as automotive, medical instruments, public
infrastructure, aerospace/ defense etc. Hirose must review before assurance of reliability can be given.
