Bestact Relay: Widely adopted in automatic train control systems for Shinkansen and conventional lines.
It is a base-implemented bestact relay with long lifespan and high reliability! 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 device continuously instructs the driver's cab with the target speed or corresponding information determined by the distance to the preceding train and track conditions, automatically applying brake control to reduce speed when exceeding the limit, and releasing the brakes when the speed falls below the target speed. It is a crucial device that ensures the safe operation of both Shinkansen and conventional trains. The board-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," which is built into the contact section, ensuring no oxidation or corrosion of the contacts, and has proven high reliability under various operating environments compared to other products. Bestact achieves a long-lasting product with excellent environmental resistance and vibration resistance due to our unique structure, which differs from conventional lead switches. Customers looking for relays or those who are not satisfied with existing relays are welcome to consult us.
