Delock N Male Crimp Connector for LMR-400 with Heat Shrink Tubing 91768

For RF technicians and wireless network installers, terminating LMR-400 coaxial cable demands a connector that preserves signal integrity. The Delock 91768 N male crimp connector is engineered for exactly that—a precision-machined, 50 Ohm N-type plug that attaches to LMR-400 and equivalent cables via a secure crimp connection. The included heat shrink tubing provides strain relief and environmental sealing, making this connector suitable for both indoor and outdoor antenna runs.

Key specifications

• Connector type: N male (plug)
• Termination style: Crimp
• Impedance: 50 Ohm
• Frequency range: DC to 11 GHz
• VSWR: 1.2 max at 6 GHz
• Compatible cables: LMR-400, RG-8, RG-213, RG-214, Belden 9913
• Cable diameter: approx. 10.3 mm
• Body material: Nickel-plated brass
• Center contact: Gold-plated brass
• Insulator: PTFE
• Operating temperature: -55 °C to 155 °C
• Included accessories: Heat shrink tubing

Why choose it

Low VSWR and gold-plated contacts ensure minimal signal loss and excellent conductivity. The nickel-plated brass body resists corrosion, while the PTFE insulator maintains stable performance across a wide temperature range. The crimp design provides a robust, permanent connection that withstands vibration and pulling forces.

Ideal use cases

• Terminating LMR-400 cables for cellular, Wi-Fi, and radio antenna systems
• Building low-loss RF jumpers in telecom installations
• Repairing or extending coaxial runs in broadcast and microwave links
• Outdoor installations where weatherproofing is required (with heat shrink)

Good to know

The connector is designed for standard crimp tools with appropriate dies for the cable and ferrule. The included heat shrink tubing should be applied over the cable-connector junction after crimping to provide additional strain relief and moisture protection. For best results, follow standard cable preparation dimensions for LMR-400.
