The Amphenol® 348 Series connector
provides reliability and high contact
density. Qualified to MIL-C-81511,
these connectors can accommodate a
minimum of three circuits to a maxi-
mum of one hundred and fifty five cir-
cuits.
Amphenol® 348 Series connectors
are available in two basic construc-
tions: Long (Series I) and Standard
(Series II). The Series I features
100% scoop-proof construction
(potential contact damage minimized
by recessed pins). Series II, Standard
connectors are scoop-proof when the
pin contacts are specified in the
receptacle shell only.
Each construction, Series I and
Series II, features a single one-piece
molded dielectric retention system
that locks the contacts in place. The
contacts are crimp type, either power
or shielded, and available in sizes 12,
16, 20 and 23-28 or 23-22 with wire
size accommodations from 12
through 32 AWG.
The Amphenol® 348 Series is a light-
weight, compact connector offered in
4 shell styles: straight plug, square
flange receptacle, single hole mount-
ing receptacle and cable receptacle. It
is environmentally resistant and will
operate at sea level to a voltage of
600 VAC (RMS). It will perform under
high temperature vibration, testing
through 150°C (see specifications on
page 2).

specifications
Materials and Finishes:
pin contact (standard) - copper base alloy, gold plated per 50
micro inches min. per MIL-G-45204 over suitable underplate.
socket contact (standard) - copper base alloy, gold plated per
MIL-G-45204 over suitable underplate. Hood material is stainless
steel.
shell - aluminum alloy finish for E class connectors - cadmium plate
over suitable underplate.
inserts - high grade dielectric material
Maintenance Aging - All contacts shall be removed and installed
for 10 cycles. After 10th cycle, contact insertion and retention
forces are as shown in table:
* Applies to both 23-28 and 23-22 contact sizes.
Durability - After 500 mating-unmating cycles at a maximum rate
of 300 cycles per hour, connectors shall not show any damage det-
rimental to the operation of the connector.
Corrosion - After salt spray testing per method 1001, condition B,
MIL-STD-1344 connectors shall show no exposure of basis metal
which will affect performance.
Dielectric Withstanding Voltage - Connectors shall show no evi-
dence of breakdown or flashover when subjected to the test volt-
ages and altitudes specified in table. Corona shall not be
considered as breakdown. (Sea level tests performed per method
3001 of MIL-STD-1344; Altitude tests per method 1005, condition
C, of MIL-STD-202).

Fluid Immersion - Unmated connectors shall be immersed fully in
fluids specified in table. At least one connector must be immersed
in each fluid type. After the immersion period and a drying period of
1 hour, the connectors must remain completely functional.
Moisture Resistance - Mated connectors shall have an insulation
resistance of 500 megohms or greater at 25°C after moisture test-
ing per MIL-STD-202, method 106.
Thermal Shock - Connectors shall remain completely functional
after being subjected to the temperature extremes specified below:
* Tested in accordance with method 1003, of MIL-STD-1344 per test conditions
listed.
Vibration - Connectors shall undergo vibration testing per method
2005, test condition IV, MIL-STD-1344 in low and high temperature
extremes of preceding table with all contacts connected in series,
and a current flow of 100 milliamperes. There shall be no circuit
interruption longer than 1 micro-second.
Physical Shock - The application of 1/2 sine-wave transient shock
impulses of 50 gravity units to 3 planes for 11 milli-seconds, with
test voltage applied to series connected contacts, shall result in no
discontinuity longer than 1 micro-second. Connectors shall not be
damaged, parts shall not become loose.
Temperature Life - Mated connectors shall perform satisfactorily
after being subjected to ambient temperatures specified, per class
for 1000 hrs.
EMI Shielding Effectiveness - As measured in a triaxial EMI leak-
age tester, connector shells with grounding springs shall exhibit a
radio frequency attenuation equal to or greater than the following:

Alternate Positions
To avoid cross-plugging problems in applications requiring the use of
more than one 348 Series connector of the same size and arrange-
ment, alternate positions are available as indicated in the charts below.
A plug with a given position number (1 through 6) will mate with a
receptacle with the same position number. The angular rotation A, B, C
or D is the same whether the connector has pin or socket inserts.
Inserts are not rotated in relation to the master key/keyway.
Shown below is a view from the front face of a receptacle. The view for
the front face of a plug is the same except the direction of rotation of
the angles is opposite of that shown for the receptacle.
