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: MIL-C-26500 Classes Amphenol/ Pyle Series Classes Hardware Description The insert design utilizes a combination of resilient and rigid insulators to offer 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 conditions. In Firewall Class K connectors the resilient insert forms the primary contact seal and is bonded to a molded ceramic rigid insert. The insert assembly is physically bonded and mechanically retained to the inside surface of the stainless steel shell, providing a voidless, monoblock configuration impervious to adverse environments. Finish Class R: (Environmental Resistant) A Aluminum Alloy Anodize Class G M Aluminum Alloy Chromium Class E R Stainless Steel Passivated Class K Firewall FPK/FYL Stainless Steel Passivated Class H Hermetic HC CRS/Stainless Steel Various A pressure seal at the connector interface is accomplished through the aid of a coupling device which compresses the front resilient insulations and thus offers a seal around each contact which prevents the passage of air or moisture through the contact cavity. Back resilient insulators are designed with a triple sealing grip at each wire hole to offer positive sealing and prevent wicking of moisture through the connector without the use of external clamping rings or adapters. 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 terminated outside the connector assembly and inserted into the appropriate cavity by means of a hand tool. 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. 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. Fluid/Temperature Resistance The fluorosilicone compound elastomer, developed by PyleNational, 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 hydraulic 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, glycol, and alkaline cleaning solutions of pH 10 or higher. Test methods are as defined in MIL-C-26500 specification. Alternate compounds have been developed by Pyle-National to solve unique user requirements not addressed by the specifications. Alternate Keying All MIL-C-26500 Series Connectors with aluminum and stainless steel hardware, can be furnished with normal or any of five alternate key positions. (See page 4). Each plug shell has a master key and four alternate keys. The position of the alternate keys in relation to the fixed master key determines the key identification. Inserts are bonded to the shell in relation to the master key, thus allowing positive protection against mismating when differing circuits exist side by side. Connectors have the capability of resisting high ambient temperatures up to 200C (392F) for long periods of time, thus contributing to an extended connector life. Connectors will withstand a combined ambient and internal temperature due to thermal rise of current carrying capacity of 238C (469F). Amphenol(R)/Pyle(R) Firewall, Class K, connectors have the inherent ability to resist high temperatures up to 460F (total temperature) for extended periods of time and can resist short time exposures (20 minutes) to prevent passage of a direct 2000F flame. 2 MIL-C-26500 specifications TEST REQUIREMENTS MILITARY SPECIFICATIONS PYLE CONNECTOR CAPABILITIES Air Leakage (Classes E, G, R & K) 1 cu. inch per hr. max. -55C (-67F) Comply Altitude Immersion (Classes E, G, R & K) Sea level 1 inch of mercury, 3 cycles (IR 5000 megohms hi-pot 1500 volts-submerged) Comply Contact Retention (Classes E, G, R & K) Size 20 contact 20 lbs. min.

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, Type 4 and Type 5) or spacer (Type 2 and Type 3) butts against contact. Fully seat contact in nest bushing of crimp tool and crimp in one full stroke. (Follow same crimping procedures except use nest bushing crimping 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 assembly and slide inner ferrule 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 above. Then for Type 1, Type 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. 28 Type 1 Shielded/Coaxial Contacts, cont. for MIL-C-26500 cylindrical connectors Cable Stripping Strip cable jacket, braid and dielectric to the dimensions shown in the table on page 28. Make all cuts square and sharp, being careful not to nick braid, dielectric, or center conductor when cutting. If conductor ends fray, twist them to their normal lay.

NOTE: Amphenol and Pyle tools are interchangeable. 31 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 insulation as it is a functional part of the sealing system. Contact Size Wire Size Stripping Length 20 20 to 24 .170" - .201" 16 16 to 18 .207" - .238" 12 12 to 14 .207" - .238" Follow steps 1 - 4, as shown below, for proper contact crimping: 1. Insert stripped wire into contact pocket until it is visible through inspection hole. 2. Carefully seat contact in crimp tool positioner. 3. Crimp in one full stroke. (The ratchet will not release jaws until tool has completed stroke). 4. Inspect crimp for wire visibility through inspection hole. 32 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 alignment of removal tool with contact must be coaxial with axis of connector. 3. Exert 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.
