SMB F BH CRIMP for LMR100/RG174/RG316 Cable

Description

The SMB Female Bulkhead Crimp Connector is a specialized RF interface designed for space-constrained environments requiring high-density mounting and frequent mating cycles. This connector is specifically optimized for small-diameter cables (approx. 2.5mm–2.8mm OD), including LMR-100, RG-174, and RG-316. The “Bulkhead” design features a threaded front-end with an integrated D-flat (or round) profile, allowing it to be securely mounted through an equipment chassis or enclosure wall using the provided hex nut and lock washer.

Engineered for DC to 4 GHz applications, the SMB interface utilizes a snap-on coupling mechanism that provides a secure, vibration-proof connection without the need for threading. The gold-plated brass body and center contact ensure exceptionally low contact resistance and superior corrosion protection. The crimp-style termination for both the center pin and the outer ferrule provides a high-strength mechanical bond, making it ideal for telecommunications, GPS, and automotive infotainment systems where reliability and speed of assembly are critical.

Key Technical Advantages

• Universal Micro-Cable Compatibility: Specifically designed to fit the exact tolerances of LMR-100, RG-174, and RG-316 cables, ensuring a perfect impedance match and minimal signal loss.

• Superior Chassis Stability: The bulkhead mounting hardware provides a rigid, ground-referenced connection point that withstands mechanical torque and environmental stress.

• High-Frequency Performance: Maintains a low VSWR (Voltage Standing Wave Ratio) up to 4 GHz, supporting high-speed data and RF signal transmission in subminiature profiles.

• Snap-On Coupling Efficiency: Reduces installation and maintenance time by allowing quick, secure mating without the risk of over-tightening or cross-threading common with SMA connectors.

• Corrosion-Resistant Gold Plating: High-grade gold-over-nickel plating ensures a durable contact surface that resists oxidation even in high-humidity environments.

Key Features

• Interface Type: SMB Female (Jack) with snap-on mating mechanism.

• Mounting Style: Bulkhead Front-Mount (Chassis/Panel) with hex nut and washer included.

• Cable Compatibility: Optimized for 50-Ohm LMR-100, RG-174, RG-188, and RG-316 coaxial cables.

• Gold-Plated Contacts: Ensures maximum electrical conductivity and signal integrity across thousands of mating cycles.

• Crimp-Crimp Termination: Secure crimp design for both the center conductor and the outer shield ferrule for industrial-grade pull strength.
