SMP Male PCB Mount Limited Detent RF Connector Engagement Depth 2.79
The SMP is an ultra-miniature RF coaxial connector featuring a push-on or snap coupling mechanism, notable for its diminutive form factor, lightweight construction, exceptional resistance to seismic activities, and wideband operation capabilities. It is engineered to support frequencies up to 30GHz, with some models capable of extending this range up to 40GHz. The plug variant of the SMP presents three distinct interface choices: full detent, limited detent, and smooth bore (which includes variants with anti-backout features). Offering PCB mount, cable mount, and inline adapter options, this connector provides adaptable interconnection solutions suitable for multiple applications such as board-to-board mating, blind mating setups, and rack-and-panel mounting scenarios, all while maintaining high levels of packaging density. The SMP is an ideal connector for environments that demand high reliability and modularity.

Applications
1. Modular Electronic Devices: The small form factor of SMP connectors makes them ideal for use in modular electronic systems where there is a need for high-density interconnections. This is particularly prevalent in industries such as aerospace, defense, and telecommunications equipment where space is at a premium.
2. RF/Microwave Applications: SMP connectors are frequently used in radio frequency (RF) and microwave applications because they can handle a broad range of frequencies, from DC to 40 GHz or even higher. This makes them suitable for communication systems, antenna connections, and broadband installations.
3. High-Speed Data Transmission: With the capability to support high frequencies, SMP connectors are also used in applications that require high-speed data transmission, such as in networking equipment and other digital communication systems.
