The Amphenol TV-CTV Tri-Start MIL-DTL-38999 Series III connector (like the TVPS00RF2561PA) is a miniature circular connector engineered for use in rigorous environments, such as military aircraft, commercial airlines, armored vehicles, and shipboard systems. These connectors excel under wide temperature ranges, high vibrations, and exposure to various contaminants, providing reliable signal integrity and exceptional EMI shielding (up to 65 dB at 10 GHz). They feature a self-locking design, a broad range of military and commercial accessories, and are fully intermatable with other MIL-DTL-38999 series III connectors. The design includes features like scoop-proof pin contacts, multiple keyways for proper alignment, and optional space-rated outgassing, making them suitable for critical industrial and aerospace applications.
