BNC 75

Product catalog summary

Introduction
The document provides comprehensive information on BNC connectors, known for their quick and reliable engagement through a two-pin bayonet coupling system. Radiall offers these connectors in 50Ω and 75Ω impedances, which are intermateable, and available in various designs including a low-cost range and the triaxial BNC TRX series.

General Characteristics
BNC connectors are globally standardized for their strength, reliability, and excellent RF performance, complying with standards such as MIL-C-39012, IEC 169-8, and CECC 22120.

Applications
These connectors are utilized in civil and military radio-telecommunication equipment, test and measurement, video communication, broadcast, industrial networks, and general electronics.

Electrical Characteristics
The document outlines the electrical characteristics for both 50Ω and 75Ω BNC connectors, including frequency range, impedance, VSWR, working voltage, and RF leakage. For example, 75Ω connectors support frequencies up to 6 GHz and a working voltage of 500 Vrms.

Mechanical Characteristics
BNC connectors are designed for durability with a mating endurance of 1000 cycles, featuring a bayonet coupling system with specific engagement forces and torque requirements.

Environmental Characteristics
These connectors operate in temperatures from -65°C to +165°C and are resistant to moisture, corrosion, vibration, and shock, adhering to various MIL standards.

Materials and Plating
Constructed from materials like brass and beryllium copper, with plating options such as nickel and gold, the insulators are typically made from PTFE.

Interface Specifications
Detailed dimensions for various BNC interfaces, including both 50Ω and 75Ω versions, are provided in millimeters and inches.

Packaging
Standard packaging typically includes 100 pieces per package.
