AMP M Series
Pin and Socket Connectors
Power Contacts
Type I, Crimp, Snap-In, Size 12
Precision screw-machined pin and socket, Size 12 contacts,
they are used in Special M Series and “G” Series connectors,
and are inserted into the same cavities as Miniature Coaxial
contacts. These contacts feature a high normal force which
provides a low resistance in significant applications. Mating
entry is closed-ended to prevent damage from stubbing due
to misalignment. Beryllium copper springs are used to provide
contact normal force and are assisted by a stainless steel hood
which provides anti-overstress assurance. Single contact cur-
rent rating is 23 amperes at 30°C Temperature Rise.
See page 36 for product details.
Type XII, Crimp-Type
Precision formed male and female contacts used in CPC Series
3 and 4, Special M Series and “G” Series connectors, these con-
tacts offer a low cost power option which provides additional
applied cost savings when terminated with semiautomatic
application equipment. The contact body is made from 100%
copper, which provides for excellent conductivity. Spring char-
acteristics are derived from a captive stainless steel spring
which assists the dual cantilever spring members of the female
contact. Single contact current rating is 35 amperes at 30°C
Temperature Rise.
See page 38 for product details.
High Current Upgrades
Precision screw-machined pin and socket contacts have
increased current capability. All upgraded contacts use the
high amperage Louvertac contact band. The design of this
contact allows for increased current in the same form factor.
For example, Type II/Type III+ upgraded contacts increase the
current from 13 amperes free air
to 23 amperes free air at a 30°C Temperature Rise.
