Mar.1.2019 Copyright 2019 HIROSE ELECTRIC CO., LTD. All Rights Reserved.
Housing walls are thick while the connector remains small.
■Features
1. Small-sized connector
0.8mm Pitch, 1.75mm Height, 4.1mm Depth. Suitable for
small-sized applications.
2. Small but robust structure
The housing is designed with thick walls while remaining
small. This produces a strong, robust connector that
resists damage.
3. Suitable for high current applications.
The maximum current of 2.5A (using 2-pos 28 AWG wire)
is achieved by using highly conductive material and
appropriate contact force.
Robust structure prevents damage while routing wiring.
Fig.1
4. BOX shaped contact prevents deformation.
The BOX shaped crimp contact prevents deformation
during assembly and contributes to the overall stability
and robustness.
◆Box
shaped contact structure
5. Visual check insures fully mated Plug and Receptacle
The housing is designed with an open side that allows for
visual inspection to insure the connectors are fully mated
preventing accidental disconnect.
6. Glow Wire compliance (Compliant with IEC 60695-2-11)
7. Halogen-free
Chlorine and bromine levels are below standard values of
IEC 61249-2-21.
Br : less than 900ppm, Cl : less than 900ppm,
Br + Cl : less than 1,500ppm.
The Box shaped structure of the crimp contact prevents deformation.
Fig.2
◆Allows
for visual inspection of the mating process.
Incomplete mating
Exposed contact
Mating complete
The contact is exposed in the
half-mated state.
Mating is complete when the
contact is no longer visible.
The mated condition can be visually checked.
Fig.3
In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.
