Easy to replace! Outstanding contact reliability! Long-lasting plug-in relay.
Plug-in type relay RB series
Railway vehicles, elevators, steel, electricity, etc., have a proven track record in various markets! You will understand the high contact reliability once you use it! This is the RB series of plug-in relays.
Our plug-in relay RB series is used in various markets such as railway vehicles, elevators, steel, and power, thanks to its high contact reliability. Being a plug-in type, it is also easy to replace. This product incorporates our original power lead switch "Bestact" at the contact point, which prevents oxidation and corrosion, proving high reliability in various operating environments compared to other products. Bestact achieves long-lasting performance with excellent environmental resistance and vibration resistance due to our unique structure, which differs from conventional lead switches. 【Product Features】*Comparison with equivalent products from other companies ○ "High contact reliability": Low failure rate and long lifespan due to unique contact mechanism ○ "Excellent environmental resistance": Minimal long-term degradation from external environments and strong against high temperatures and humidity ○ "High vibration and shock resistance": Strong against vibration and shock due to unique contact mechanism ○ "Supports a range from small to large capacity": Operates with high contact reliability from small to large capacities ○ "Low maintenance frequency": Long lifespan reduces maintenance burden Customers looking for relays or those dissatisfied with existing relays are welcome to consult with us. The Yaskawa Electric Group is here to assist you.

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.
