SMB M BH CRIMP for LMR100/RG174/RG316 Cable

Description

The SMB Male Bulkhead Crimp Connector is a subminiature RF solution designed for equipment manufacturers and system integrators who require a reliable signal transition through a panel or chassis. This connector is specifically optimized for micro-diameter cables (approx. 2.5mm–2.8mm OD), including LMR-100, RG-174, and RG-316. The “Bulkhead” configuration features a threaded outer body with a front-mount hex nut and washer, allowing for a rigid, vibration-resistant installation through a D-flat or round cutout in an enclosure wall.

Engineered for performance from DC up to 4 GHz, the SMB male (plug) interface utilizes a professional snap-on coupling mechanism that provides a secure mechanical lock without the need for tools or torque. The high-grade gold-plated center contact and brass body ensure minimal signal attenuation and superior protection against oxidation. The crimp-style termination for both the center conductor and the outer ferrule ensures an industrial-strength bond, making it ideal for automotive telematics, GPS receivers, and medical instrumentation where space is limited but mechanical reliability is paramount.

Key Technical Advantages

• Secure Panel Integration: The bulkhead mounting hardware creates a high-stability grounding point that protects internal circuitry from external cable tension.

• Precision Micro-Cable Match: Calibrated to the exact tolerances of LMR-100, RG-174, and RG-316 to maintain 50-Ohm impedance and reduce VSWR.

• Vibration-Resistant Mating: The snap-on interface is designed to resist loosening in high-vibration environments, providing a more stable connection than traditional threaded connectors in mobile applications.

• Superior Corrosion Resistance: Featuring premium gold plating on critical contact surfaces to ensure long-term electrical conductivity in humid or high-salt environments.

• High-Density Small Cell Ready: The subminiature footprint allows for multiple connectors to be mounted in close proximity on a single chassis plate, perfect for MIMO and DAS applications.

Key Features

• Interface Type: SMB Male (Plug) with snap-on mating mechanism.

• Mounting Configuration: Bulkhead Front-Mount with integrated D-flat to prevent rotation during installation.

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

• Termination Method: Dual-crimp design (center pin and outer sleeve) for maximum pull-off resistance.

• Premium Materials: Constructed with a gold-plated center contact and a high-performance PTFE (Teflon) insulator for thermal stability.
