Description
The N-Type female bulkhead connector is an essential component for secure enclosure interfacing, prized for its mechanical stability and environmental sealing. This variant features a Bulkhead (BH) mounting design, including a mounting nut and washer, allowing for a high-integrity, fixed connection through panel walls up to a specific thickness. It is specialized for the 2.5mm to 3mm cable class, specifically optimized for high-performance LMR100 and high-temperature RG316.
As a female interface (jack), it provides the external threaded mating point for a chassis, allowing for a seamless transition from internal micro-coaxial jumpers to external antenna feeders. This connector utilizes a standard hex-crimp termination system for the outer conductor, providing a high-strength mechanical bond and maximum shielding effectiveness. Manufactured with a durable nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and reliable operation up to 6 GHz, ensuring signal integrity in high-density electronic environments.
Key Technical Advantages
-
Secure Bulkhead Mounting: The threaded body and hex-nut design provide a robust, non-rotating mounting solution through enclosure walls, ensuring a high-integrity ground connection.
-
Thin-Gauge Cable Match: Specifically calibrated for the small OD cable family (RG174/RG316), ensuring a precise mechanical fit and optimized electrical transition for flexible internal jumpers.
-
Integrated Environmental Seal: Designed for use with an O-ring or gasket to provide a moisture-proof barrier at the panel entry point, protecting internal electronics.
-
Vibration-Proof Threaded Interface: The 5/8-24 threaded outer shell ensures a secure, locked mating with male connectors, resisting loosening in industrial, mobile, or marine environments.
-
High-Grade Materials: Features a nickel-plated brass body and a gold-plated center contact for maximum corrosion resistance and consistent signal clarity over the life of the product.
