Features
1. Two stacking height options
Two separate heights available : 0.8 and 1.3mm
Molded structure
The molded structure provides security and
insulation between the terminals and the board
2. Ultra space-saving design
With its drastically reduced depth of 1.98mm,
this series can fit in the tightest designs.

3. Two point contact system
The two point contact structure encloses the
plug contacts and assures a completely secure
connection. (Fig.1)
4. Superior tactile feedback
A clear tactile click is delivered upon the
successful completion of the mating process.
(Fig. 2)
5. Drop and shock resistant structure
Dimples were designed into the plug contacts ;
they increase retention force and absorb shock
when dropped.

6. User friendly operations
Insertion force (N)
The low-profile connectors with stacking height
of 0.8mm maintain the mating self-alignment
range of 0.3mm, securing easy mating
operations.

7. No pattern prohibited area
No restrictions on PCB layout patter n are
imposed, as thin molding technology maintains
the effective mating length of 0.2mm while
achieving complete insulation between the
bottom side of the receptacle and the board.
