[Case Study] Shinkansen and Conventional Line Automatic Train Control System Bestact Relay
It is a long-life, highly reliable base-implemented best actuator relay! Simultaneous direct control of logic and power circuits is possible! It has a long track record in railways!
It is used as an interface relay for brake control in the ATC (Automatic Train Control) system, which automatically regulates the train's speed to be below the speed limit. The ATC system continuously instructs the driver's cab with the target speed or corresponding information determined by the distance to the preceding train and track conditions. It automatically applies brake control to reduce speed when exceeding the limit and releases the brakes when the speed is below the target speed, making it a crucial device for ensuring the safe operation of both Shinkansen and conventional trains. The substrate-mounted Bestact relay is used for various loads and signal control relays in railway vehicles, adapting to the vehicle environment and contributing to improved system reliability and reduced maintenance frequency due to its long lifespan. This product features our original power lead switch, "Bestact," at the contact part, which prevents oxidation and corrosion of the contacts, demonstrating high reliability in various operating environments compared to other products. Bestact achieves a long lifespan with excellent environmental resistance and vibration resistance due to our unique structure, which differs from typical lead switches. Customers looking for relays or those dissatisfied with existing relays are welcome to consult us.

Company information
For over 40 years, our relays and sensors have been trusted and used in various markets where reliability and safety are essential, such as in Shinkansen (bullet trains) and steel manufacturing. With advantages such as an electrical lifespan that is twice that of standard relays and a failure rate of 1/20 under low loads, we contribute to improving equipment reliability while also reducing running costs by decreasing the frequency of replacements. Leveraging the excellent environmental resistance of our products, they perform well even in harsh conditions, such as in vegetable factories where humidity is present.
