Secure Connection at Higher Frequencies

February 2024

Designed for high-performance in demanding environments, SMP-LOCK ensures a robust and stable link, even in the face of vibration and shock. The SMP range provides a secure connection in small spaces or at high frequencies, allowing you to trust that the connection won’t fail in critical applications. 

High Frequency

The SMP interface operates in the frequency range of DC - 40 GHz without compromising electrical performance. 


The SMP-LOCK features a robust locking mechanism that reduces susceptibility to vibration and shock, preventing accidental disconnection. This locking feature is crucial in environments where vibration, shock, or other challenging conditions may pose a risk to the integrity of the connection, such as in aerospace, defense and telecommunication.


SMP-LOCK is a sub-miniature lock-on connector. These small, lightweight connectors are suitable for cable-to-cable or cable-to-module connections in applications like radars, avionics, satellites, missiles and more.

Find an even smaller version in the microminiature SMPM-LOCK, with a strong locking mechanism that significantly boosts the interface's retention force and guards against unintentional disconnections.
