Substrate-type relay RZDR-E widely adopted in automatic train control (ATC) systems.
RZDR-E Series
It is a relay with a long lifespan and high reliability, featuring a foundation implementation type! Simultaneous direct control of logic and power circuits is possible! With a 4-contact configuration, it has a wide range of applications!
The RZDR-E type printed circuit board-mounted multipole 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 is installed in automatic train control (ATC) devices, contributing to the precise operation and safe driving of railway vehicles. Additionally, this relay serves as an interface relay for brake control. The contact section of this product features our original power lead switch "Bestact," which is built-in and free from oxidation and corrosion, proving to have high reliability in various usage environments compared to other products. Bestact achieves a long lifespan with excellent environmental resistance and vibration resistance through our unique structure, which differs from conventional lead switches.

Company information
For over 40 years, our relays and sensors have been used in various markets where reliability and safety are required, such as in Shinkansen (bullet trains) and steel manufacturing. With advantages such as an electrical lifespan that is twice that of general relays and a failure rate that is 1/20 under minimal loads, our products 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 environments, such as in vegetable factories where humidity is present.
