Additional Contact Styles
from Amphenol, cont.
Amphenol offers broad flexibility to connector
users. Our contact engineers can help in the
selection of the best contact style and function-
ality for your interconnect needs. Here are more
Amphenol contact choices:
FILTER PI TYPE TUBULAR AND PLANAR ARRAY
CONTACT ASSEMBLIES
Amphenol filter/transient protection connectors utilize filter contact designs to
provide protection for sensitive electronic circuits; protection in VHF, UHF, HF and
other filter ranges. Amphenol filter connectors offer the advantage of internal
housing of the filter device within a wide range of connector packages - virtually all
major Mil-spec cylindricals and rectangular series. Housing the filter protection
within the connector eliminates costly and bulky exterior discrete protection
devices. Header assemblies (see right) allow for easy separation and easy
termination of connectors when attaching to flex or pc boards. They allow for
electrical testing that would adversely affect sensitive diodes, MOV’s or filter
capacitors. See Amphenol EMI Filter/Transient Protection Connector Catalog
12-120* for further information.
RADSOK
Amphenol’s RADSOK
ration within the socket cylinder. As the male pin is inserted, axial members
in the female socket half deflect, imparting high current flow across the
connection with minimal voltage loss. Another advantage of the
RADSOK
been incorporated into three of the large industrial families of connec-
tors; the GT series, the P-Lok series and 5015 types. These connectors,
known as Amphe-Power
amperages. Amphenol Industrial Operations division also provides a wide
range of power to board interconnects utilizing the RADSOK
These provide high amperage connection to busbars, wires and circuit boards. See
Amphenol Industrial Brochure, SL-391. (online at www.amphenol-industrial.com)

High power RADSOK
Commercial Air, and are also being designed into LRM interconnects for high
speed data transfer.
LOW MATING FORCE HIGH CYCLE, BRISTLE BRUSH CONTACTS
Amphenol bristle brush or B
wire that are bundled together. 70% to 90% reduction in mating/unmating forces is
achieved over conventional contacts, and the brush contact has proven durability
and long contact life. Hybrid Low Mating Force connectors can be designed with
combinations of brush and coax/twinax/power contacts or fiber optic termini. See
pages 45 & 46 of this publication, and refer to Amphenol catalog 12-035, Low
Mating Force Rectangular Connectors for more information on Brush contacts
(online at www.amphenol-aerospace.com).
LRM Surface Mount Connectors also use brush technology as the standard contact
type, but can have other contact types combined in the module and backplane
inserts. There is a high level of design versatility in LRM designs - one bay, two bay,
three bay, or more configurations with many shell designs, plus the
ability to combine contact types. See pages 45 & 46 of this
publication, and refer to Amphenol LRM catalog 12-037.
STANDARD CRIMP CONTACTS
Crimp contacts are used throughout the connector industry for
standard interconnection. Amphenol supplies crimp contacts that are
designed and qualified to various military/customer specifications and M39029
slash sheets. Numerous contact sizes and finishes are available for use with front
or rear release connector applications.
