Protection of the contact
springs 



No over elongation of the
contact springs possible
under normal circum-
stances 



No possibility to connect
from the rear side 



Protection against 
mechanical damage 



Good guiding in the cavity 



Secondary locking possible

automatically 

In addition there are usually
two lances on the steel to

the contact securely in the 
housing. 

The AMP MCP Contact 
System is mainly used in the
automotive industry. Each
contact consists of a flat 
receptacle, which mates with
a flat tab. Every contact has
got a steel 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 tab. The
closed spring has got several
functions and also different
advantages for the complete
contact system. 

The main advantages of the
body are: 



Several contact points 



Large range of wire sizes
(from 0.2 mm

Tabs and receptacles can be
applied in both sealed and 
unsealed connectors. 

AMP MCP contacts can 
be fast and economically
arranged to the lead using
Tyco Electronics application
tooling.
