Substrate type relay RZDR-E widely adopted in VVVF inverter control devices.
Multi-pole relay RZDR-E type for VVVF inverter control device with mounted circuit board
Expanded application range with a 4-contact configuration! Simultaneous direct control of logic and power circuits is possible! It is the RZDR-E relay with long life and high reliability for surface mount!
The substrate-mounted multipole relay RZDR-E type is installed in VVVF inverter control devices and contributes to the precise operation and safe driving of railway vehicles. This relay also performs well in the harsh operating environment beneath the vehicle. It 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. The contact section of this product incorporates our original power lead switch "Bestact," which prevents oxidation and corrosion of the contacts, demonstrating high reliability under various operating conditions 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.

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.
