The diameter 1.5 mm and dia-
meter 2.5 mm round contact
systems developed by Tyco
Electronics is mainly used in
the automotive industry. Due
to its wide range of perform-
ance possibilities, this contact
system is in use in the engine
compartment for aggregate or
sensor connections.
Every contact has got a steel
cantilever spring and a copper
alloy body.
The two-piece contact design
means that the electrical and
mechanical properties are
separated. One end of the
contact body is crimped to
wire and the other end mates
with the matching pin.
The closed cantilever spring
has got several functions and
also different advantages for
the complete contact system.
In addition there are several
lances on the steel to spring.
These serve to look the con-
tact securely in the housing.
Sockets and pins can be
applied on both sealed and
unsealed connectors.
The diameter 1.5 mm and dia-
meter 2.5 mm contact system
can be fast and economically
arranged to the lead using
Tyco Electronics application
tooling.
