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.
