MIL-C-26500 Connectors
features
Amphenol®/Pyle® MIL-C-26500 Connectors are qualified to Mil-
itary Specification MIL-C-26500, as well as n umerous high per-
formance customer specifications. As the chart below
indicates, these connectors are available with aluminum or
stainless steel shells – bayonet or threaded – and are qualified
to meet the specifications of these MIL-C-26500 classes:
Crimp Contacts
Rear insertable, front releasable, crimp style contacts are
machined from a copper alloy material, plated gold over nickel,
and are qualified to specification MIL-C-39029. Contacts are
crimp ter m inated outside the connector assembly and inser ted
into the appropriate cavity by means of a hand tool.
Socket contacts utilize a multi-tined construction and feature a
“C” spring which grips the tines, and thus insures consistent
and repetitive insertion/withdrawal forces. Contact tines are
protected by a stainless steel shroud.
An optional pencil-clip thermocouple socket design is also
offered. See page 27 for more information on thermocouple
contacts.
Alternate Keying
All MIL-C-26500 Series Connectors with aluminum and stain-
less steel hardware , can be furnished with normal or any of fiv e
alternate key positions. (See page 4).
Each plug shell has a master key and four alternate keys. The
position of the alter nate keys in relation to the fixed master key
determines the key identification. Inserts are bonded to the
shell in relation to the master ke y, thus allowing positive protec-
tion against mismating when differing circuits e xist side b y side .

Connector Sealing
The insert design utilizes a combination of resilient and rigid
insulators to off er a connector with total sealing capabilities.
Bonded interfaces between the resilient and rigid dielectric
components eliminate air voids and thus protect the connector
from potential degradation due to moisture and altitude condi-
tions.
In Firewall Class K connectors the resilient inser t forms the pri-
mary contact seal and is bonded to a molded ceramic rigid
inser t. The insert assembly is physically bonded and mechani-
cally retained to the inside surface of the stainless steel shell,
providing a voidless, monoblock configuration impervious to
adverse environments.
A pressure seal at the connector interface is accomplished
through the aid of a coupling de vice which compresses the front
resilient insulations and thus offers a seal around each contact
which prevents the passage of air or moisture through the con-
tact cavity. Back resilient insulators are designed with a triple
sealing grip at each wire hole to offer positive sealing and pre-
vent wicking of moisture through the connector without the use
of exter nal clamping rings or adapters.
In addition, a dynamic “O” ring seal engages the front of the
plug shell when connectors are mated and offers yet another
barrier to moisture and containments.
Fluid/Temperature Resistance
The fluorosilicone compound elastomer, developed by Pyle-
National, exceeds all specification requirements and provides
excellent resistance to tear, compression set, fluids, and high
temperatures.
Amphenol/Pyle’s fluorosilicone compound offered in Class R,
G, E and K is capable of reliability resisting MIL-H-5606 hydrau-
lic fluid and MIL-L-9236 lubricating oil; as well as MIL-L-7808
and MIL-L-23699 lubricating oils, MIL-J-5624 (JP-5) jet fuel, gly-
col, and alkaline cleaning solutions of pH 10 or higher. Test
methods are as defined in MIL-C-26500 specification. Alter nate
compounds have been developed by Pyle-National to solve
unique user requirements not addressed by the specifications.
Connectors have the capability of resisting high ambient tem-
peratures up to 200°C (392°F) for long periods of time, thus
contributing to an extended connector life. Connectors will with-
stand a combined ambient and internal temperature due to
thermal rise of current carrying capacity of 238°C (469°F).
Amphenol®/Pyle® Firewall, Class K, connectors have the inher-
ent ability to resist high temperatures up to 460°F (total temper-
ature) for extended periods of time and can resist short time
exposures (20 minutes) to prevent passage of a direct 2000°F
flame.

MIL-C-26500 – how to order
aluminum/stainless steel,
ratchet lock plug, mating flange receptacle
Amphenol®/Pyle® connectors are specifically designed to meet high
vibration requirements above and beyond the specification require-
ments of MIL-C-26500. The plug connector features a unique non-
decoupling device which offers a ratchet mechanism designed to
engage as the threaded connectors approach a bottomed condi-
tion. Connector coupling assembly continues to ratchet for approxi-
mately 120 degrees until the mated connectors reach a complete
metal-to-metal bottomed condition. The ratchet device maintains
the connectors in a fully coupled condition, thus eliminating the
need for safety wiring.
Additional features include:
Modified accessor y thread to accommodate MIL-C-83723 back-
shell hardware.
Rear accessory teeth are f eatured on both the plug and recepta-
cle shell to assure non-rotation of accessory hardware

MIL-C-26500 – 48 Series
receptacle short skirt
Receptacle Short Skirt – Aluminum – Bayonet Coupling
Shor ter, lighter, and more economical than the standard MIL-C-26500 connector recepta-
cles, the 48 Series receptacle shor t skirt comes in two versions: with standard flange and
with reduced flange. Both versions are 1.100” long which is .275” shor ter than the length
of the standard MIL-C-26500 connector. They have molded epoxy fiberglass inserts and
can operate continuously up to 125°C (257°F), but otherwise they offer the same environ-
mental sealing, from the panel out, as standard MIL-C-26500 connectors. They have bay-
onet coupling and mate with standard MIL-C-26500 plugs. The hard dielectric inserts , with
resilient face seal and molded-in gold plated solder cup pin contacts, are available in
insert arrangements shown in the chart below.

Step 1 Slide sealing boot or sleeve and outer ferrule onto cable and strip cable as shown at right.
After stripping, slide spacer over center conductor as shown for Type 2 and Type 3.
For Type 3 slide spacer under wire braid.
Step 2
Insert stripped center conductor into contact until wire shows through inspection hole and dielectric (Type 1,
T ype 4 and Type 5) or spacer (T ype 2 and Type 3) butts against contact. Fully seat contact in nest b ushing
of crimp tool and crimp in one full stroke. (F ollo w same crimping procedures e xcept use nest b ushing crimp-
ing tool from table above).
Step 3 Slightly flair out ends of wire braid to facilitate insertion of inner ferrule of body assembly.
Do not comb braid.
Step 4 Install center contact in body assemb ly and slide inner f errule underneath wire braid as shown. Push center
contact until it is locked in place in the body assembly. Pull lightly on cable to make sure that contact is
securely locked in place.
Step 5 Slide outer ferrule over braid and up against body as shown. There should be no slack in the wire braid.
Crimp the outer ferrule with proper tool from table abo ve. Then for Type 1, T ype 3 and Type 5 slide sealing
sleeve toward contact until sleeve touches outer ferrule.
Step 6 Insert the assembled shielded contact into the connector in the same way as the standard contact using
applicable insertion tool (see page 28). This completes assembly for Type 1, Type 2, Type 3 and Type 5.
Step 7 To complete assembly for Type 4, push sealing boot into connector grommet until O-ring riser of boot snaps
into place and seals the assembly.

Assembly Instructions for MIL-C-26500
Connectors
Contact Termination
Contacts should be crimped to the wire with MS Standard hand
crimping tools or specification automatic crimping machines.
When stripping the wire avoid nicking wires or damaging the insula-
tion as it is a functional part of the sealing system.
Follow steps 1 – 4, as shown below, for proper contact crimping:
Contact
Size Wire Size Stripping Length
20 20 to 24 .170” – .201”
16 16 to 18 .207” – .238”
12 12 to 14 .207” – .238”
1. Inser t stripped wire into contact pocket until it
is visible through inspection hole.
3. Crimp in one full stroke. (The ratchet will not
release jaws until tool has completed stroke).
2. Carefully seat contact in crimp tool positioner.
4. Inspect crimp for wire visibility through inspec-
tion hole.

Assembly Instructions for MIL-C-26500
Connectors, cont.
Contact Insertion into the Connector
The following steps are recommended for assembly. NOTE:
The Pyle Miniature Connector is designed with a unique sealing principle.
Assembly of contacts into the connector must be made with reasonable care
to avoid damage to the silicone rubber insert.
1. Lubricate wire cavities in back face of insert with a very thin film of DC-200
Silicone Oil or equal before inserting contacts.
2. Locate contact in insertion tool (as shown in illustration).
3. Align contact with hole in rear face of insert. The alignment of insertion tool
with contact must be coaxial with the axis of the connector. When contact
has entered rear seal portion of insert, maintain alignment of contact and
tool parallel to, and in line with hole. Insert contact to full depth. Seating of
the contact in the retention collet is audible. The contact insertion force is
less than five pounds.
4. Extract insertion tool, keeping it aligned with hole.
Contact Removal from the Connector
A contact is removed from the connector insert with the extraction tool as follows:
1. Set the spacer sleeve in the proper position for removal of male or female
contact.
2. Place tool over the contact and insert into front face of cavity. The align-
ment of removal tool with contact must be coaxial with axis of connector.
3. Exer t a nominal force axially (from 5 to 10 lbs.) to release retention collet.
Spacer sleeve will shoulder at front face of insulation when tool is inserted
to proper depth.
4. Push extraction plunger to force the contact out of the rear of the insert.
5. Grasp contact or wire at rear face of insert and complete the extraction.
6. Remove extraction tool axially.
7. After using extraction tool the spacer sleeve should be set forward in last
notch to protect the end of the plunger guide.
Panel Mounting Two receptacle shell styles, flange mount and D-hole mount, are available for
panel mounting. See the applicable drawings for mounting hole dimensions.
The square flange receptacle, sizes 10 through 22, is fastened to the panel
with four size #4-40 machine screws. The 24 and 28 size shells are fastened
with #6-32 machine screws.
