This connector was developed for the higher operating temperatures inherent in today's newest high performance aircraft and aircraft engines. These connectors meet the performance requirements of the following specifications:

• Recommended operating voltage to 600 VAC (RMS) at
  sea level
  
• Complete environmental sealing includes individual contact seals and a silicone elastomer interfacial seal with raised barriers around each pin, a shell-to-shell seal and an insert-to-shell seal. Sealing over a wide range of wire diameters is assured by a triple-webbed
  grommet design
  
• Captive coupling nut prevents tampering, while a reduced coupling ring ramp allows easier mating
  
• Incorporates crimp rear release contacts in sizes 12, 16 and 20; contact arrangements accept
  2 to 61 circuits
• Contacts conform to MIL-C-39029 and use standard qualified rear-release type plastic tools
• Insertion and removal of contacts from the rear of the connector assures no damage to the front that might affect the sealing characteristics
• Grommets are constructed of tear-resistant elastomer and experience no degradation when exposed to a broad range of fluids
• Closed entry socket side of the insert is designed with a lead-in chamfer and a hard face that will accept a pin contact bent within pre-established limits

This series provides many choices within the range of a medium sized, environmentally resistant
cylindrical connector. With three coupling style choices - bayonet, threaded and quick-disconnect
the versatility of this family makes it increasingly popular for panel mount, box mount and line-to-line applications in aircraft. For general duty environmentally resistant requirements, this family of connectors provides a wide range of interconnection solutions.

MIL-C-83723 Series Ill-high temperature - Using MIL-C-83723 Series Ill design concepts, Pyle-National has also developed a series of High Temperature firewall connectors, that are capable of operation at 260" C/500° F. A 100% scoop-proof version of the high temperature connector is also available under specificaton ESC 11/Pyle HTK Series. In addition, this connector series incorporates a unique sealing grommet that is capable of sealing on standard diameter wire as well as Kapton wire of reduced diameter.
