HIGH RELIABILITY AND EMI-SHIELDING IN EXTREME ENVIRONMENTS
Amphenol‘s TV-CTV Tri-Start MIL-DTL-38999 Series III connectors have high-density contact arrangements in a miniature circular shell. Originally designed for the high-performance requirements of military and commercial aircraft, these circular connectors are perfect for applications requiring extremely reliable interconnections. Amphenol TV-CTV connectors are quick-mating and environmentally-sealed. See our full list of product features for Amphenol TV-CTV Tri-Start connectors in the specifications below.
Features
High-Reliability D38999 - TV style connectors are used in some of the most rigorous environments and must perform flawlessly under wide temperature ranges, high vibrations and be resistant to a vast array of contaminants. Visual confirmation of mating is provided by the plug coupling nut covering a red band on the mating shell.
Outstanding EMI-Shielding Protection These connectors provide excellent signal integrity due to the shielded mating system that utilizes 360-degree shell grounding fingers, providing protection of up to 65 dB at 10 GHz.
Operates at Extreme Temperatures These connectors operate in temperatures from -85°F to +392°F (-65°C to +200°C).
High-Density Connectors If space is at a premium, TV connectors offer up to 128 contacts per connector. Ideally suited for the demands of digital electronics on fly-by wire aircraft, advanced robotics, and critical industrial equipment.
Self-Locking Connector Systems Self-locking coupling nuts and self-locking endbell accessory hardware provide the best performance for threaded connectors in high-vibration applications.
Broad Range of Military and Commercial Accessories Many military-standard endbells to M85049 specifications and a wide array of cable termination styles are available. Straight, 45 and 90-degree endbells come in many styles from cost-effective standard clamp to shielded, environmentally-sealed and everything in between.
Contact Protection TV connectors are designed to be scoop-proof. Pin contacts are recessed to prevent contact damage and contact shorting when connector halves are mated.
MIL-DTL-38999-Approved TV’s are fully-interminable and intermountable with all other manufacturer’s MIL-DTL-38999 series III connectors.
Ground Plane options are now available.

EXCERPT FROM MIL-DTL-38999K
3.43.2 JAN brand. The United States Government has adopted, and is exercising legitimate control over the certification marks “JAN” and “J”, respectively, to indicate that items so marked or identified are manufactured to, and meet all the requirements of military specification. Accordingly, items acquired to, and meeting all of the criteria specified herein and in applicable specifications shall bear the certification mark “JAN” except that items too small to bear the certification mark “JAN” shall bear the letter “J”. The “JAN” or “J” shall be placed immediately before the PIN except that if such location would place a hardship on the manufacturer in connection with such marking, the “JAN” or “J” may be located on the first line above or below the PIN. Items furnished under contracts or orders which either permit or require deviation from the conditions or requirements specified herein or in applicable specifications shall not bear “JAN” or “J”. In the event an item fails to meet the requirements of this specification and the applicable specification sheets or associated detail specifications, the manufacturer shall remove the “JAN” or the “J” from the sample tested and also from all items represented by the sample. The “JAN” or “J” certification mark shall not be used on products acquired to contractor drawings or specification. The United States Government has obtained Certificate of Registration No. 504,860 for the certification mark “JAN”.
Note: The “JAN” or “J” is not part of the PIN but indicates a certification.
