482GB Series
Circular Environmental Connector
Amphenol
Description
The 482 Series are EMI filter connectors which are designed to meet
the mechanical and environmental requirements of MIL-C-26482.
The connectors will accept filter, power or grounding contacts or EMI
seal plugs or any combination thereof.
Connectors are available with front release rear removable crimp type
contacts or fixed contacts with solder bucket or pin tail termination.
Mating Connector Information

Introduction
AMPHENOL’s Filter connectors are a system of reliability
engineered receptacles, plugs, contacts and accessories,
designed to provide a wide range of performance and
servicing features not previously available with ordinary EMI
filtering connectors.
These connectors are rugged enough to operate reliably under
high physical stress, and in the demanding environmental
conditions required of power connections.
The patented stress isolated EMI filter is composed of a
ceramic element attached to a sturdy contact in a way that
dampens all connector stresses and virtually eliminates the
chance of ceramic fracture due to vibration, thermal and
physical shock.
Once inserted in the connector, the filter contact is engaged
by a Microstrip grounding plate designed to achieve maximum
insertion loss and to inhibit resonances due to series
inductance.
The use of filter connectors has the following advantages:
•
•
•
•
•
Space saving
Weight saving
Reduction in solder connections
Eliminates requirement for RFI screened box
Provides low impedance ground plane for filter network

Keyway Orientations
Datum
Datum is always taken from major key or keyway. In
receptacles the major keyway always remains fixed in
relation to the mounting flange. For the B, C, E and F
orientations, the three bayonet locations and associated
minor keyways are rotated complete, in accordance with
the table below.
3 Pins spaced
120
o
apart
N.B. The accompanying diagram shows a receptacle
shell, with keyways. Corresponding key orientations
for a mating plug shell are therefore always clockwise.
