Mating Face Area
Approximately 50% Reduced
Fig.1
■Overview
DH Series is an impedance controlled interface connector
for high speed transmission.
With a contact pitch of 1mm, the DH Series has a compact
and thin design, enabling higher density mounting
compared to generic half-pitch connectors.
4 different lock styles are available to meet various
application needs.

■Features
Metal Shielding
1. Small Design
With a contact pitch of 1mm and mounted pitch of 0.5mm,
the mating face area is reduced by approximately 50%
when compared to existing Hirose half-pitch connectors.
(Fig.1)
PCB
Fig.2
2. Robust Design
The D-shaped shell design enhances prying force.
Through-hole mounting of the shell and retention tabs
increases PCB retention force.
3. Unique Contact Arrangement for IDC Termination
The stagerred 2 row IDC contact arrangement reduces
plug size. Additionally, the 2 types of press plates, white
and black, can be used to prevent mis-wiring.
4. Excellent Shielding for EMI Prevention
The plug is covered with a metal shield and the ground
can be dropped to the panel or board. (Fig. 2)
5. Wide Variation
Wide product range available including screw lock types,
one touch lock types and variations to accommodate an
array of panel thicknesses.
6. Applicable for High Speed Data Transmission
Twinaxial cabling enables high speed transmission.
(Varies based on cable length and board)
In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.

*For 7. IDC and 8. Cable clamping, one of the tools listed in each ①, ②, and ③ are required (select one).
*Customers that already have the HI-Flex termination press may use it for product assembly.
*DH/IDCK-MP listed in 7. IDC and 8. Cable clamping is the same tool. If there is at least one, then both IDC and cable
clamping can be completed by switching out the IDC attachment with the caulking attachment. Accordingly, two of both DH/
IDCK-MP and the HIFLEX termination press are required for mass production.
