General Purpose Relays |

General purpose reed relays can be used in a variety of applications and markets. Including but not limited to automated test equipment, medical equipment, industrial, telecommunications, and much more. Additionally these reed relays come in a variety of sizes, switching configurations, and other options. And since the reed switch is the base component these relays will switch billions of reliable operations (load dependent). Our most popular general purpose reed relays include the BE, DIL, and DIP series. Our versatile BE series can house up to 5 switches in a single relay. And offers a high insulation version up to 10^13 ohms. All the before mentioned series feature a dual-in-line pin-out. The DIP series has a low-profile version as well.
