High performance and high reliability - Reach relays with many achievements in the global railway industry.
To extend the lifespan of railway vehicles, reduce replacement costs, and decrease failures, we propose changing from resin cover relays to nitrogen-sealed relays.
✓ Since it is a sealed relay, iron powder generated from sliding wear in railways and other sources is attracted by the coil's magnetic field and enters the interior through the gaps in the relay's resin cover, affecting the contacts, and the influence of other dust on the contacts is eliminated. ✓ The contacts operate in nitrogen gas, making it difficult for sparks to occur, thereby reducing the impact of contact noise caused by sparks on electronic devices. Of course, the possibility of ignition due to sparks is also eliminated. ✓ The contact return when not energized uses a unique structure with permanent magnets and does not use springs. Therefore, operational failures caused by spring fatigue do not occur. ✓ In the event of contact welding, it is a fail-safe mechanism that stops the operation of other contacts as well. ✓ We can propose not only the relay itself but also relay panels and relay racks that contribute to compactness. ✓ We can also propose relay circuits.
