B2B engineering procurement

Quote a production requirement

Send model number, voltage/current, contact form, coil voltage, target application and annual quantity. Engineering sales will confirm fit, datasheet and lead time.

Start RFQ
B2C sample purchase

Buy standard samples online

Sample-ready products can be ordered from the online catalog. For models without price, use RFQ first so specifications are verified before purchase.

Open Sample Store
Cross reference

Replace an existing relay

Share competitor part number, footprint and electrical limits. We will map it to a standard SHR MiRelay part or a custom design option.
