■Features
●Secure hold during the soldering operation
1. Simple, one step mating
Built-in locks assure correct and complete mating
with just a single, downward push on the plug.
2. Vertical mating style
The vertical mating style and built-in, self aligning
features are efficient and eliminates the need for
additional space that would be required with a
horizontal mating style connector.
Insulator
Contacts
3. Designed for high voltage applications
Wide contact pitch and creepage distance maintain
stable and safe performance at high voltage levels.
4. Secure attachment to the board
Hold-down
Four solder points are provided to keep the headers
firmly secured to the PCB.
Fig.2
5. Secure hold during the soldering operation.
The 12 mm pitch version incorporates a built in holddown feature that helps keep the connector aligned
during the soldering operation.
6. UL, C-UL, and TÜV certified (12mm pitch only)
7. RoHS compliant
■Applications
LCD TV backlights, FPD power supplies and other
applications requiring small high-voltage connectors.
In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.

Note 1 : Up to 2 cycles of Reflow soldering are possible under the same
conditions, provided that there is a return to normal temperature
between the first and second cycle.
Note 2 : The temperature profile indicates the board surface temperature at
the point of contact with the connector terminals.
Peak temperature : 260ç for 10 seconds max.
Manual soldering : 350ç for 3 seconds max.
Thickness : 0.15mm
Open area ratio : 100%
Maximum of 0.03mm at the connector center, with both ends of the connector as
reference points.
Refer to "Board to cable connectors Use Handbook".
Refer to “Board to cable connectors Use Handbook”.
The crimp contact termination must be performed using specified tools.
All dimensions and crimp conditions are listed in applicable Crimp Condition
Table and Crimping Quality Standards Manual.

8. Precautions
■ Mating
1 Socket will self-align in the header.
2 Align the Socket over the header and firmly push-down at the “O” symbol
until both locks are fully engaged.
Tactile “click” sensation will confirm fully locked condition.

Step 2
■The crimped contacts must be fully inserted in the crimp socket horizontally
and will self-guide itself in the proper position
■The header must be mounted on the PC board when mating with the
corresponding socket.
■Differences in colors shade of the molded components will not affect form,
fit or function.
■Contact HRS if additional information is required.
