Description
The DIN 1.6/5.6 series, universally designated as the L9 connector, is a high-performance RF interface designed specifically for the demanding requirements of digital telephony. This female (jack) variant features a bulkhead mounting configuration, allowing it to be securely fixed through an equipment panel or chassis wall. The integrated mounting nut and lock washer ensure a gas-tight mechanical fit, while the D-flat (non-rotate) body profile prevents the connector from spinning during installation or maintenance patching.
Specifically calibrated for BT3002 (Type 2002)—the industry-standard 75-Ohm coaxial cable for E1, E3, and DS3 digital transmission—this connector maintains strict impedance control. It utilizes a professional dual-crimp termination for both the center pin and the outer ferrule, providing a permanent, gas-tight mechanical bond that ensures consistent electrical performance. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers exceptional signal integrity and high shielding effectiveness, protecting sensitive digital data streams from interference in high-density infrastructure.
Key Technical Advantages
-
Secure Bulkhead Integration: The threaded body allows for direct chassis mounting, providing a robust feed-through point for internal equipment wiring to external patch cables.
-
BT3002 Precision Matching: Engineered specifically for the geometry of Type 2002 cable, ensuring an optimized electrical transition and minimal return loss for UK and European telecommunications standards.
-
Non-Rotate D-Flat Profile: Features a flat-sided mounting section that locks into the panel cutout, preventing axial rotation and protecting internal solder or crimp joints.
-
75-Ohm System Integrity: Specifically calibrated to eliminate impedance mismatches, preventing bit errors and signal jitter in high-capacity digital circuits.
-
Superior Corrosion Protection: Premium gold-over-nickel plating on all critical contact surfaces ensures low contact resistance and long-term durability in mission-critical infrastructure.
