Features
1. Two stacking height options
Two separate heights available: 0.8 and 1.3 mm
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 1.98 mm,
this series can fit in the tightest designs.

Point A
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.

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