RG316 and LEONI DACAR 462 are two common coaxial cables, mainly used to transmit high-frequency signals, with good anti-interference performance and reliability. Although their basic functions are similar, there are significant differences in their functions, especially in terms of construction, size, temperature resistance, and shielding performance.
Overview
RG316 is also known as "micro coaxial cable" due to its small size and good flexibility. It meets the MIL-C-17 military standard and is widely used in aerospace, wireless communication systems and military equipment, especially in high temperature environments.
LEONI DACAR 462 is a high-performance coaxial cable produced by LEONI, Germany, designed for high-speed data transmission and RF signal transmission in automotive applications. It is widely used in ADAS, in-vehicle infotainment systems, GPS navigation systems, cameras, and vehicle communication systems, with high-speed transmission capabilities, excellent anti-interference performance, and stable and reliable signal transmission.
Features
1. Construction
RG316: Features a stranded silver-coated copper-clad steel center conductor, a PTFE (polytetrafluoroethylene) dielectric, a silver-plated copper braided shield, and a FEP (fluorinated ethylene propylene) jacket - combining high temperature resistance with good EMI protection.
LEONI DACAR 462: Utilizes high-performance polypropylene (PP) and cross-linked polyethylene (XPE) dielectric materials to ensure durability and superior electrical performance.
2. Size
RG316: Outer diameter typically around 1.6 mm (may vary slightly by manufacturer). It is a fine-diameter coaxial cable ideal for applications with limited space requiring high-frequency signal transmission.
LEONI DACAR 462: Multi-core construction with a larger cable diameter, generally above 2.8 mm (depending on core count and jacket). Suitable for automotive electronic systems requiring multi-core wiring and effective shielding.
3. Temperature Range
RG316: Excellent high-temperature performance, typically rated for -55°C to +200°C, making it suitable for extreme temperature environments.
LEONI DACAR 462: Meets automotive-grade temperature standards, generally rated for -40°C to +105°C, suitable for diverse and demanding automotive environments.
4. EMI Shielding and Interference Resistance
RG316: Features a single-layer braided shield providing moderate EMI protection, suitable for environments with relatively low to moderate electromagnetic interference, such as communication equipment, lab instruments, and some industrial automation devices.
LEONI DACAR 462: Employs multi-layer shielding combining braided and foil shields for superior EMI suppression, essential for automotive systems requiring stable, high-speed signal integrity.
