2. Short- circuit/ electric shock
prevention design

Receptacle/Cross-Section

The female terminals are enclosed
in highly insulating resin.

Female terminals are used on the board side
receptacle, and live parts are completely covered
with resin, enhancing assembly safety.

liminates two risks●Board damage due to ashort circuit between
adjacent terminals●Operator electric
shock from touching
the contacts

3. High Heat Resistance up to125℃- Up to 125℃
- Suitable for automotive and other high- heatapplications
Note : Includes the temperature rise due to current flow.

4. High Vibration Resistanceouble- a ered Spring esign

Precautions

1. Forcing the connector out might cause damage.
If challenging to remove, gently press down once and then release the lock.
2. Always disconnect the power before reseating the connector.
3. Avoid touching the terminal area when the power is active, as it's hazardous.
4. For harnessing guidelines, please consult a Hirose representative.

While Taking into Consideration
Specifications mentioned in this catalog are reference values.
When considering to order or use this product, please review 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, the warranty of the product may beaffected.
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.
