Radiall's New SMPM Connector with Locking System

March 2027

Radiall designed this microminiature product to answer customer demands for smaller connectors that provide reliable security and performance. SMPM-LOCK's robust locking mechanism dramatically increases the retention force of the interface and prevents accidental disconnection. It features performances up to 65 GHz.

Radiall added a locking system to the SMPM interface to secure connections in any type of installation, even in the tightest spaces. Keeping the demand for smaller connectors in mind, Radiall reduced the length of this product by over 40% compared to SMP-LOCK. The right-angle plug version saves even more space.

This locking system is simple to implement, quick to lock and very secure when the two interfaces are connected. To secure the two interfaces, connect the plug with the jack and bring the locking ring to the specific groove. For an easy and secure connection, Radiall recommends using a specific mating/unmating tool. To disconnect the two interfaces, simply slide the locking nut back. This will unlock the connector and allow you to unmate the plug.
