[Features]This is a JIS standard panel-mounting screw type receptacle manufactured by Nanaboshi Electric Mfg. A robust shell is achieved by die-casting. It is mounted on a panel and connected to a straight plug. The main body is made of die-cast, so it has a robust finish. Some JIS C 5432 compliant products are available, so any other company's products compliant with the same standard can be mated.
