Emerson Connectivity Solutions offers the Johnson line of SMPM connectors, a sub-miniature, push-on style micro interface. These connectors are approximately 35% smaller than SMP designs, enabling higher-density connection points while maintaining solid Return Loss performance from DC up to 65 GHz. The SMPM family includes PC mount, End Launch, and .047 cabled styles, available in straight and right-angled configurations. Male connectors come in full detent or smooth bore designs for adjustable separation forces. The SMPM bullet adapter provides blind-mate functionality, mitigating radial and axial misalignment with minimal impact on VSWR and signal losses. These connectors are ideal for test equipment and racked electronics where space is limited and mating boards is challenging. For systems with tighter spacing requirements, multi-channel blocks for straight or right-angle interfaces can be custom-designed.
