Frequently Asked Questions

Can I directly replace an Omron or Schneider relay with an MG relay?

Yes, the pin layout follows the same international standard for direct replacement, but you should verify the coil voltage and mounting dimensions match.

Yes, it’s more reliable against vibration-induced loosening and can reduce installation time by about 60%.

MG relays are designed for a wide operating temperature range, typically from -40°C to +70°C, ensuring reliable operation in harsh environments.

What international certifications do your relays have?

MG relays carry comprehensive global approvals including UL (North America), CE, TUV, VDE (Europe), and comply with RoHS 2.0 & REACH environmental standards, ensuring smooth export for your end equipment.

Electromechanical relays offer two key advantages: true physical isolation (zero leakage current when off) for safety, and superior surge withstand capability, making them more robust for harsh industrial power environments.

It uses a magnetic field to stretch and extinguish the powerful spark (arc) created when breaking a high DC current, preventing the contacts from welding together and significantly extending relay life.
