February 25, 2021
Hirose Electric is happy to announce that the Ethernet interface connector for railways, TJ*L Series, has been installed by Central Japan Railway Company for use on the N700S Tokaido Sanyo Shinkansen bullet train. The bullet train begins commercial operation on July 1, 2020.
● Why this Ethernet Connectors with User Friendly Snap-in Lock Design was Chosen
Conventional connectors used in railways are mainly locked by screw tightening. However these connectors have poor operability, require screw tightening management and do not meet the demand for increased information transmission volume as railways evolve.
In order to solve such problems, Hirose Electric developed the market leading TJ*L Series (* is a 2 digit number to identify the mounting method) of interface connectors capable of transmitting 100Mbps Ethernet signals with a snap-in lock design for next generation railways.
This connector has a snap-in lock design for easy operation, and has high quality and performance that passes the severe vibration and shock tests required for railroad vehicles. These features has been highly evaluated and are the basis in which TJ*L Series was selected for the N700S. In addition to Central Japan Railway Company, this product is also used by other private railway companies.
