Connector Usage Precautions

Sep.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.

1. Assembly and installation of connectors and components should be done in reference to the specified
assembly procedures and with the proper amount of tightening torque.
If the torque is too low or too strong it may result in loosening or damage. ( Please contact your Hirose
representative for the correct procedures. )2. After mating a connector, pull on the cable slightly to confirm mating and that the connector is firmly in place.

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, publicinfrastructure, aerospace/ defense etc. Hirose must review before assurance of reliability can be given.
