Amphenol Heavy Duty
Cylindrical Connectors
MIL-C-22992, Class L
Class L connectors are available only in the specific con-
figurations prescribed by MIL-C-22992 for either military
or industrial applications. This rigid configuration control
assures correct interconnection of electrical circuits for
maximum safety and reliability. Controlled parameters
include:
Connector shell style and contact type - wall mount
and cable connecting receptacles are supplied with
socket contacts only and always lead from the power
source. Plugs (with coupling rings) have pin contacts only
and always lead to the equipment end.
Shell size - the direct relationship of shell size to current
carrying capability reduces the possibility of inadequate
wiring for heavy electrical loads.†
Keyway position - four positions of the main keyway are
used to discriminate between the following power
sources:
two wire D.C
two wire single phase A.C.
three wire single phase A.C.
four wire three phase A.C.
Insert rotation - when carrying alternating current (A.C),
different angular rotations of the insert within the connec-
tor shell are used to distinguish between 60 Hertz and
400 Hertz circuits.

Other outstanding design features:
Arc quenching design - recessed socket contacts within
the insert create an arc suppressing chamber which pro-
tects the user when connectors are separated under
load.
Programmed coupling sequence - grounding and neu-
tral contacts engage before power contacts.
Waterproof design - a unique combination of grommets
and seals provides waterproofing in any condition -
mated or unmated, capped or uncapped.
Rugged construction - machined from high strength
aluminum. Straight-line attachment of accessories elimi-
nates possibility of cable twisting or misalignment.
Accessories - supplied with all Class L connectors as
indicated on the individual connector descriptions.
Replacement accessories may be ordered separately.
