Applications• Designed for the roughest industrial applications, providing
reliable, rugged service for power, control and instrumentation.• For use in the roughest industrial applications, ranging from: — Process and control — Marine — Oil and gas — Machine tool — Industrial — Power distribution systems — Transportation
Features• Environmental connector rated IP68.• Designed to meet or exceed the electrical performance
requirements of Mil-C-5015.• Large coupling sleeve, secured with captive set screws.• Quick coupling, double-lead thread resists cross-mating
problems and provides positive mating.• Durable, scratch resistant hardcoat plating.• All hardware is machined using 6061T aluminum bar stock.• Vast family of reversible inserts.• Power, signal and mixed applications.• From 1 to 68 contact positions.• Connector designs offer crimp style terminals as standard:
— Crimp insert arrangements allow the contacts to be inserted or removed from the rear through use of insertion/extraction tools without removing the insert from the connector body.
— Solder/pressure insert contacts cannot be removed without fi rst pushing out the insert from the shell body. However the contacts can be serviced while the insert is locked in the shell hardware by simply repairing each individual wire termination.
• Inserts provide water, vapor, moisture and dust resistance and fi t into standard hardware components
• Contact sizes for 18, 16, 12, 10, 8, 4, 1/0, 4/0, 313 to 777 MCM AWG.
• Shell sizes 6, 8, 10, 12, 14. Contact your local sales representative for other shell sizes.
• Extensive array of hardware and strain relief options.• Custom cable assembly manufactured to support customer
application specifi c designs.• Silver plated contacts standard. Gold contacts optional.• Stainless steel and brass components available. Contact your
local sales representative for details.• Intermateable and interchangeable with other connector brands
available in the market.

Crimp Inserts
The crimp style inserts utilize a 2 piece insert design comprised of a rigid front insulator and a resilient backcap. Each of the rear backcaps are color coded to indicate use for pin contacts - red, or socket contacts - green. The contacts are crimp terminated outside the insert utilizing the correct wire size and ready for insertion into the contact cavity. The insert should be positioned into the shell hardware prior to insertion. When the insert is positioned into the shell hardware each individual contact can then be easily inserted into each cavity using the proper insertion tool. To ease the assembly of the contacts into the insert cavities, the inserts provide number markings on the front and rear of the insert. When all contacts are assembled into the insert, each contact shoulder is securely positioned into the front rigid insulator body providing a stabilized and positive alignment of the contacts. The inserts are locked or pressurized into place when the clamp nut (receptacle) or cable adapter (plug/in-line receptacle) is threaded and tightened against the plastic pressure seal shoulder. The crimp inserts allows each contact to be individually serviced/repaired by removal from the insert. In order to relieve the locked or pressured contacts, the rear retaining nut (receptacle) or the cable adapter(plug/in-line receptacle) must be backed off the rear of the shell hardware. Once removed each contact can be easily removed by use of the proper sized removal tool. Contacts will be released at the rear of the connector.

Contact Ratings — Wire Well Dimensions — All Minimum in Millimeters (Inches)
• Mil Spec Ampere Ratings: (MIL-C-39029). Based on the combination of the following:— The amount of current which an individual pin and socket contact may carry is a function of contact material and design effi ciency of
the pin and socket system as well as the ability of the primary conductor insulation to resist temperature rises due to inherent copper losses and bundling factors.
— Total current carrying capacity of the connector is a function of the insert temperature which is rated at 100 °C (212 °F) for continuous operation. The total operating temperature is the summation of the ambient temperature plus the temperature rise resulting from the thermal losses of each contact.
— NEC specifi cations may be used as a general reference on the subject in as much as pertinent cable de-rating data is included.• NEC Non-Circuit Breaking Ampere Ratings
— The non-interrupting current ratings, shown in the table below are based on the temperature of the contacts being within the range specifi ed by Underwriter’s Laboratories, Inc. when wire sizes are selected in accordance with the National Electrical Code.
— When multiple conductors are used, the load factor and temperature rise based on ambient and total insert temperature must be taken into consideration.

Electrical Performance — Service Voltage Ratings (for various specifications)
NEC voltage rating is designated by a service voltage rating letter which is shown listed in the table below corresponds to the insert configurations listings on the following pages. The voltage to which contact inserts are limited is a function of the dielectric separation between adjacent contacts and between contacts and shell.
