Shogyo International Corporation has introduced a new, unique line of locking DC jacks and plugs. Two raised strips of metal, positioned 180° apart on the outside of the plug barrel, are designed to align with two mating slots running through the outside of the jack enclosure. When the plug is fully inserted into the mating jack, the metal strips align with and insert into the mating slots. A simple 90° twisting of the plug establishes and maintains a secure lock between both jack and plug, and prevents accidental disengagement.
Plug model MP-121CR is an assembly-type plug and model MP-121CR1 is for molding onto cable assemblies. Jack model MJ-179LR mates with both plug models.
