Overview
The N-Type connector is a medium-sized, weatherproof, threaded RF coaxial connector designed for high-performance and mission-critical applications. Originally invented by Paul Neill at Bell Labs in the 1940s, it was one of the first connectors capable of carrying microwave frequencies. Today, it remains a global standard for robust and reliable signal transmission.
Key Features & Benefits
- Rugged & Weatherproof Design: Featuring a threaded coupling mechanism (5/8-24 UNEF), N-Type connectors provide a secure, vibration-resistant, and waterproof connection, making them ideal for harsh outdoor environments.
- Excellent Electrical Performance: Available in both 50Ω (standard) and 75Ω versions, N-Type connectors support a wide frequency range from DC to 11 GHz, with precision models reaching up to 18 GHz.
- High Power Handling: Compared to smaller connectors like SMA, the N-Type's larger size allows for superior power handling and lower voltage standing wave ratio (VSWR), ensuring minimal signal loss.
- Versatile Configurations: Our product line includes various styles such as Straight, Right Angle, Bulkhead, Flange mount, and multiple termination types (Crimp, Solder, Clamp) to suit diverse cable assemblies and equipment.
Typical Applications
- Telecommunications Infrastructure (Base Stations, Antennas)
- Outdoor Wireless Systems (Wi-Fi, GPS, IoT)
- Radar & Aerospace Systems
- Test & Measurement Equipment
- Broadcast and Industrial Radio

Selection Guide:
- Choose N-Type for outdoor, high-power, and harsh environment applications where waterproofing and mechanical stability are critical.
- Choose SMA for high-frequency, compact indoor applications like PCB modules and consumer electronics.
- Choose BNC for quick-connect requirements in lower frequency (under 4 GHz) test and measurement scenarios.
