3.7±0.15
(0.4) Effective mating length
■Features
1. Small mated height and board occupied
space
Enhanced shielding
Small pitch (0.3mm) and mated height (1.5mm)
allows use in space-restricted areas.
Plug’s height of 1.3mm and width of 2.38mm allow
its passage through narrow openings in smalldiameter hinge applications.
2. Enhanced shielding and ground connections
Metal shells on the plug and receptacle connect to
each other with a reliable multi-point ground
contacts, assuring reliable ground connection and
EMC protection.
3. Reliable lock
Fully mated condition is assured with reliable locks at
4 locations, confirming it with a distinct tactile click.
4. Reliable electrical and mechanical
connection
Despite its small mated height, unique contact
configuration assures highly reliable connection,
with effective mating length of 0.4mm.
Multi-point ground contacts
4-point lock:
2 points at each end
5. Solder wicking prevention
Nickel barriers prevent solder wicking in the critical
contact areas.
6. Durable plug construction
Formed metal shells on the top and side surfaces
form a strong and rigid assembly.
7. RoHS, Halogen-free*
*As defined by IEC61249-2-21
Br-900 ppm maximum,Cl-900 ppm maximum, Cl+Br
combined-1,500 ppm maximum
Distinct tactile click
■Connector for conductivity tests
We have a line-up of connectors for inspection,
usable for electrical testing of both plug and
receptacle connectors.
In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.

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 contacts with the connector terminals.

6.Precautions
Refer to “Nylon Connector Use Handbook”.
Maximum of 0.02mm at the connector center, with both ends of the
connector as reference points.
* Mating and un-mating of the connectors when not soldered on the
boards is not recommended as this may cause deformation of the
terminals, damage to the contacts or insulators.
* When mating/un-mating do not twist or lift by the corners. Apply the
forces evenly across the entire length and width of the connectors
taking care NOT to damage or deform soldered terminations.
* Slight discoloration on the insulating materials will not affect form,
fit or function of the connectors.

Precautions
■Mating
Mate the plug with the receptacle by pressing straight against the entire plug surface.
Do NOT un-mate the plug while holding by the terminated cable.

■Un-mating
Use a dedicated extraction tool to un-mate the plug. Insert the tool under either end of the plug (clearance) and pull straight up as
illustrated.
Do NOT un-mate the plug while holding by the terminated cable.
Extraction tool
End side (clearance)
■Routing of the fine coaxial cable after termination
Allow sufficient clearance between the plug and the fine coaxial cable to avoid sharp bend, excessive twist or pull forces applied to
the connector.
No pulling
■Other
· Do NOT mate / un-mate the connectors when receptacle is not mounted on the board.
· Different production lots may exhibit different shades of the insulator materials. No affect on form, fit or function of the connectors.
· Rework of the soldered terminations on the board-mounted receptacles is not possible.
· Sides of the metal cover protrude over the termination areas.
· Do not mate / un-mate the connectors when receptacle is not mounted on the board.
