High Life Cycle Interface Connectors
3800 Series
Hirose's Unique Contact Structure with High Durability
1) Minimum contact shaving due to a rolled surface on the bellows contact side
2) The spring contact design prevents buckling.
3) Stable contact design provides the support needed to endure 20,000 mating cycles
Provides ideal long term contact force.

■Features
1. 20,000 mating/unmating life cycle with
unique Hirose contact structure.
2. The structure utilizes a metal shell that
is 0.35 mm thick. The shell is designed
t o c ov e r t h e h o u s i n g a n d p ro t e c t
against rough mechanical operation.
The addition of reinforced metal fittings increases
t h e P C B r e t e n t i o n fo r c e a n d a l l o w s t h e s e
connectors to be mounted with commercially
available screws for the cradle type. (Fig.w)

2) Protected Guide Posts
The metal shell on the cradle provides
protection and cover to the guide posts
on the cradle plug.

3) Optional screw fastening
The cradle can be secured to the PCB with
the use of commercially available screws (M2
x 0.4 x 5) to provide additional retention force.
4) Reinforcing metal fittings
Solder is allowed to flow into the through hole and onto the
reinforcing metal fittings to increase the PCB retention force.
Commercial screw (optional)
3. Sequential mating, that features a 0.5
mm range (Fig.e)
4. Its small size and light weight design
are helpful for use in compact devices
5. Simple mating process with a tactile
cl i ck t h a t a s s u r e s p ro p e r m a t i n g
completion.
The pushbutton locking system leads to a simplified
mating process that delivers a tactile click to ensure
that the mating process was correctly completed.

Sequential Mating Structure
The No.1 and 18 contacts are the first contacts to mate, with the remaining contacts mating thereafter.
[Effective Mating Length]
1 & 18 Contact: 1.4 mm
2 to 17 Contact: 0.9 mm
6. One piece plug cover
The assembly of this connector is simplified due to
its one-piece plug cover.
