■Features
1. Small mated height and board occupied
space
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 small-
diameter hinge applications.
Enhanced shielding
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.
Multi-point ground contacts
4-point lock:
2 points at each end
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.
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*

■Connector
for conductivity tests
We have a line-up of connectors for inspection,
usable for electrical testing of both plug and
receptacle connectors.

Note 1: Includes temperature rise caused by current flow.
Note 2: The term "storage" refers to products stored for a long period prior to mounting and use.
The operating temperature and humidity range covers the non-conducting condition of connectors after board mounting
and the temporary storage conditions of transportation, etc.
Note 3: With only the connector portion at an elevated temperature level, the rated current value is set.
