basic information
■□■Features■□■ ■ By combining a plug-in line unit and power supply unit, you can freely select up to 5 line branching connections (12 patterns) and 3 types of power supplies. ■ Depending on the settings within the line unit, bidirectional or unidirectional branching connections are possible. ■ The 4W-2W conversion circuit (HYBRID) aims to achieve impedance matching (370Ω, 600Ω, 1400Ω) for two-wire lines and improve the balanced circuit. ■ By combining two or more of these devices (merging), it is also possible to expand branching connections (more than 5 branches). ■ For more details, please contact us.

Company information
Our company was founded in 1949 as a designated manufacturer of wire materials by the Ministry of Telecommunications. We have steadily established our presence by designing and manufacturing telephone and communication systems and related equipment for public enterprises such as police, railways, electricity, and broadcasting, alongside the development of related companies. We also have a significant track record in OEM products for major manufacturers. Our main products are custom-made items, which we handle from design to manufacturing, focusing on systems and products related to information and communication. Recent key products include disaster prevention information systems (JR East and JR Hokkaido), command telephone systems (various JR companies, electricity companies, and private broadcasters), remote monitoring and control systems (various JR companies, electricity companies, and telecommunications carriers), and emergency contact systems (private elementary and junior high schools). Currently, we are working on the development of the latest IT and IP systems, such as serverless IP conference call systems, to respond to the evolution of communication networks. If you present us with challenges in niche areas where major manufacturers are not proficient, we are committed to leveraging our years of accumulated experience and the latest technology to provide low-cost and quick delivery solutions. We appreciate your guidance and support.
