DIN 1.6/5.6 or L9 M Solder Type for LMR100/RG174/RG316 Cable

Description

The DIN 1.6/5.6 series, universally designated as the L9 connector, is a high-performance RF interface designed specifically for the rigorous demands of digital telephony. This male (plug) solder-type variant is optimized for micro-diameter cables, including the low-loss LMR100, flexible RG174, and high-temperature RG316. Unlike all-crimp versions, the solder-type center contact provides a fused, low-resistance electrical bond, ensuring maximum signal transparency for sensitive digital circuits where even minor impedance fluctuations can lead to data errors.

Maintaining a strict 75-Ohm impedance, this connector is essential for preventing signal reflections and bit errors in high-speed digital transmission standards like E1, E3, and DS3. The L9 plug features a precise mating design that ensures a secure electrical connection with consistent contact pressure, ideal for modular telephony hardware. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers exceptional electrical stability and superior protection against environmental oxidation in central office exchange environments and rack-mounted equipment.

Key Technical Advantages

• Permanent Solder Termination: The solder-cup center contact provides a high-conductivity fused connection, offering superior electrical permanence and lower contact resistance compared to standard crimp pins.

• Micro-Cable Precision Fit: Specifically calibrated for the dimensions of LMR100, RG174, and RG316 (approx. 2.5mm–2.8mm OD), ensuring an optimized electrical transition and minimal return loss.

• Telecommunications Grade Reliability: Designed to meet DIN 1.6/5.6 standards for digital distribution, ensuring universal compatibility with standard L9 female jack assemblies.

• High Shielding Effectiveness: The robust construction and gold-plated finish provide excellent grounding and protection against electromagnetic interference (EMI) in congested rack environments.

• Superior Corrosion Protection: Premium gold-over-nickel plating on all critical surfaces ensures long-term durability and low contact resistance in mission-critical infrastructure.

Key Features

• Interface Type: DIN 1.6/5.6 (L9) Male (Plug) with 75-Ohm impedance.
