Commercial 38999, Series III Type Composite Connectors
The Amphe-Lite Connector Series is designed for communications equip-
ment manufacturers with signal, power, RF or fiber optic interconnect
requirements in harsh environments such as communication towers, out-
door and roof-top applications. This commercial 38999, Series III type
composite connector series is ideal for communications equipment, manu-
facturing process control and medical equipment.
The Amphe-Lite offers the highest performance capabilities for severe
environment applications, and yet is cost effective enough for general duty
and non-environmental applications.
The Amphe-Lite is UL Recognized, file E115497.

Designed for Performance
Numerous advantages in performance capability are
designed into the Amphenol
®
Amphe-Lite Connector.
A positive shoulder to shoulder coupling design,
grounding fingers, and electroless nickel plating pro-
vide superior EMI shielding capability of 65 dB mini-
mum at 10 GHz.
Features and Benefits of the Amphe-Lite Series:
•
Service Class F Amphe-Lite connectors provide excellent EMI shield-
ing and grounding through electroless nickel plating and spring ground-
ing rings. Environmental sealing is ensured with interfacial seals to
prevent contact corrosion. Composite shells are completely immune to
corrosion problems.
Service Class U provides a non-conductive shell when EMI shielding is
not a criteria.
Class F Composite shells resist severe corrosion, and provide plating
endurance from salt spray exposure for a minimum of 2000 hours.
Completely mates in one 360-degree turn of the coupling nut to provide
the fastest and easiest equipment assembly and maintenance possi-
ble.
Acme threads provide coupling durability. Thicker wall sections and a
greater coupling surface area improve strength and shock resistance.
Blunting of the thread on both the coupling nut and receptacle elimi-
nates cross coupling.
Recessed pins minimize potential contact damage in this 100% scoop-
proof connector. In a blind mating application, mating shells cannot
“scoop” the pins and cause a shorting or bending of contacts.
A rigid dielectric insert with excellent electrical characteristics provides
durable protection to the contacts. The socket contacts are probe proof,
and all contacts are rear insertable and rear removable. Available in
sizes 10 power, 12, 16, 20 and 22D contacts are plated in the standard
50 micro inches minimum gold, with 100 micro inches as an option.
Conductive and non-conductive options are available. See pg. 22.
Amphe-Lite connectors allow for use of many contact types: fiber
optics, shielded coaxial, twinax ground plane versions, and power con-
tacts. (See pages 23, 24). Consult Amphenol Industrial for more infor-
mation on combinations of different types of contacts in one connector
shell - what Amphenol calls their new “Combo-C” inserts.
Non-magnetic Amphe-Lite is a new variation - Amphenol offers one of
the few 100% non-magnetic connectors with high contact density avail-
able today. See page 24.

®
Amphe-Lite connectors provide EMI
shielding capability which exceeds MIL-DTL-
38999 Series III requirements.
The Amphe-Lite connector with EMI grounding
fingers and conductive finishes has proven to be
the ultimate in EMI shielding effectiveness. The
charts at right illustrate shielding effectiveness
data which is typical of connectors tested with
the nickel finish over a wide frequency range.
These capabilities along with a 125°C tempera-
ture rating and superior moisture sealing protec-
tion provide the user with a connector that can
withstand the most rigorous application. UL RTI
rating is 105°C.

entirely in the designers hands, since he is in the best position to
know what voltage, switching surges, transients, etc. can be
expected in a particular circuit.
