SMB connectors

What are SMB connectors?

SMB connectors, also known as SMB coaxial connectors, are compact RF interfaces with a push-on coupling mechanism, designed for industrial electronics, automotive systems and embedded devices. Thanks to their reduced size and quick mating, they are ideal for RF modules and applications where space is limited.

Main types of SMB connectors

This category includes the most commonly used versions in professional applications:

• SMB Plug and SMB Jack
• Straight and right-angle configurations
• Cable-mount SMB connectors in multiple variants
• PCB-mount SMB connectors with compact profiles

These solutions cover the majority of requirements in compact products, RF modules and integrated electronic systems.

Typical applications

SMB connectors are widely used in:

• Embedded devices and compact RF modules
• Industrial electronics and control systems
• Automotive applications and RF sensors
• Portable instruments and small test equipment
• Internal device interconnections and board-to-module links

Advantages of SMB connectors

• Push-on coupling for quick and easy mating
• Compact form factor ideal for miniaturised devices
• Good RF performance across typical operating bands
• Available for cable-mount or PCB-mount integration

SMB connectors for cables

Cable-mount SMB connectors offer reduced size and fast installation, making them suitable for internal wiring, portable equipment and integrated RF assemblies.

SMB connectors for PCBs

PCB SMB connectors are designed for mechanical stability and easy integration into compact systems, available in vertical or horizontal configurations depending on board layout.

FAQ – Frequently Asked Questions

What is the difference between SMB and SMA?
SMB connectors are smaller and use a push-on coupling, while SMA connectors are more robust and support higher frequencies.

Are SMB connectors suitable for outdoor use?
Generally not; they are intended for internal installations or integration inside electronic devices.
