The 38999 family of high-density connectors was designed to work with existing MIL-Spec 38999 shells. To the end users familiar with standard 38999 connectors, this family of high-density connectors will look, feel, and perform just like the MIL-Qualified connectors. Utilizing an existing MIL-Spec 39029 size 23 contact and MIL-Spec shells, the new system is usually a drop-in connector. Even though this high-density connector has 30% more contacts, it still performs to the minimum electrical requirements of standard 38999 connectors.
Features
High-Reliability HD38999 - 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, HD38999 - TV connectors offer up to 187 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.
