The connectors of the Amphenol product series
C 148 U are characterised by a robust and
compact design, simple handling, and high
mechanical and electrical strength. These con-
nectors, designed for use in control systems
and servo-drives, thus meet all requirements
demanded of a decentralised plug-connector
system for use under rough operating condi-
tions. They are suitable for wire sizes of
0.5 mm
2
to 10 mm
2
and cover about 95% of
all possible applications.
The modular usability of the individual compo-
nents reduces the amount of stock which has
to be kept. A further advantage is the simple,
quick and reliable assembly of connectors for
equipment and cables. No special tools are
needed for inserting the contacts into the insu-
lated body.
The proven crimp technology is very suitable for
connecting wires to contacts for systems sub-
ject to vibration stresses. All of the connectors
are designed for use in electromagnetic interfer-
ence fields. The EMI protection is ensured by
the metallic construction and the full connection
of the cable shield within the connectors.
The application sector for the C 148 U series
extends from mechanical engineering to drive
solutions and decentralised control systems
with power buses.
