SMPM Connectors

Cinch Connectivity Solutions SMPM connectors are a sub-miniature, push-on style micro interfaces that are distinguished for their size (about 35% smaller than the SMP design). They are becoming increasingly popular for the two-fold design benefit of allowing for a higher-density of connection points and maintaining solid return-loss performance from DC-level frequencies up to 65 GHz.

The Johnson SMPM family includes PC-mount and end-launch styles, straight and right-angled, .047 cabled connectors, and sealable flange-mounts. All male connectors are offered as full-detent or smooth bore designs for your preference of separation forces. The SMPM bullet adapter provides the same coveted blind-mate functionality as the larger SMP connectors, mitigating radial and axial misalignment with negligible change to VSWR and other signal losses. The SMPM-series is perfect for use in test equipment and racked-electronics where footprint space is a premium and mating boards together is difficult.
