COAXIAL CONNECTORS

Product catalog summary
Product Overview: The document details specifications and descriptions of coaxial connectors, including VAA, SAA, SBA, and TAA series, designed for high-density applications in civil and military radio, supporting frequencies up to 2 GHz.
Specifications: VAA series connectors are available in gold, nickel, or tin-plated versions, with a nominal impedance of 50 Ω and a maximum operating frequency of 2 GHz. They feature a VSWR of ≤ 1.2, an operating voltage of 250 V rms, and a dielectric strength of 750 V rms, suitable for temperatures from -55˚C to +250˚C.
Mechanical Characteristics: Connectors have a mating force of 5.5 to 13 N and an unmating force of 7.5 to 20 N, designed for over 700 cycles of mechanical endurance.
Construction Details: Materials and treatments for parts like the outer shell, insulator, and contacts are specified, with the outer shell made of brass with specific plating for durability.
Assembly and Installation: Instructions for cable assembly, including flexible and semi-rigid cables, are provided, along with drilling patterns and tool specifications. Recommended cables are listed.
Safety and Liability: A safety notice emphasizes following instructions and consulting safety regulations, with LEMO disclaiming liability for improper use.
Electrical and Climatic Characteristics: Nominal impedance options are 50 Ω and 75 Ω, with maximum operating frequencies of 0.65 GHz and 1.4 GHz, respectively. The VSWR is ≤ 1.2, with testing and operating voltages of 750 V rms and 250 V rms.
Standards and Models: Connectors comply with standards like DIN 47 297-C, CECC 22230, MIL-C-17 96, and IEC CCTU10-01A, with models available for various applications.
Coupling Types: Includes screw, spring, free, and push-pull self-latching types.
Procedures: Detailed cable assembly and connector crimping instructions are provided, emphasizing the use of specific tools and dimensions.
Recommendations: For high reliability, use push-pull self-latching coupling and adapt connectors for different cables without altering technical characteristics.
Key Data from Tables: Dimensions and part numbers for connectors and coupling types are detailed, ensuring optimal performance.
Product Safety and Disclaimers: Safety instructions highlight risks of improper handling, advising inspection and trained personnel for assembly, with disclaimers on product liability.
