Product catalog summary

Overview: The 4E Series of triaxial connectors is designed for broadcasting applications, particularly in harsh environments. These connectors offer a protection index of IP66, ensuring durability and reliability in challenging conditions. The series is suitable for TV camera applications and provides excellent electromagnetic compatibility (EMC) protection.

Specifications: The connectors have an impedance of 75 Ω and operate at a frequency of up to 1.2 GHz. The voltage standing wave ratio (VSWR) is specified as 1.01 + 0.14 f according to IEC 60169-1-1 standards. Contact resistance is less than 3 mΩ, with internal screen contact resistance under 1 mΩ. The connectors are watertight when mated, conforming to IP66 standards as per IEC 60529.

Technical Characteristics: The connectors are available in various configurations, including straight plugs, fixed plugs, and adapters. They are constructed with nickel-plated brass for the body and stainless steel for the lanyard, ensuring robustness and longevity. The connectors are compatible with several cable types, including Belden and Nokia Triax cables, with specific part numbers provided for each configuration.

Dimensions and Weight: The document provides detailed dimensions for each connector type, with weights ranging from 37g to 230g depending on the model. All dimensions are specified in millimeters.

Accessories: Accessories such as plug caps, blanking caps, and bend reliefs are available for the connectors. The bend reliefs are made from polyurethane elastomer and are suitable for temperatures ranging from -40°C to +80°C in dry atmospheres. The color of the bend relief can be customized by changing the last letter of the part number.

Notes: The document includes additional notes on material specifications and ordering information, emphasizing the need to order bend reliefs separately. It also provides contact information for LEMO headquarters in Switzerland.
