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

connectors to be mounted with commercially

available screws for the cradle type. (Fig.w)

◆Receptacle

Robust Structure

1) The 0.35 mm thick metal shell protects the housing.

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

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.

Contact

No. 1

7. RoHS compliant

All materials and substances used to produce this

product comply with the RoHS free standards.

Contact No. 18

In cases where the application will demand a high level of reliability, such as automotive,

please contact a company representative for further information.
