This document is about the technical data of EB2 series miniature signal relays, introducing the basic characteristics, distribution characteristics, test data and other information of the products.
The EB2 series miniature signal relays are designed for use in communication, measurement, and factory automation applications. This handbook provides the basic characteristics, test data, and environmental specifications needed for designing circuits that incorporate these relays.
The document includes detailed information on coil voltage limits, temperature rise, contact materials, mechanical life tests, and a range of environmental tests such as high‑temperature, low‑temperature, moisture resistance, heat‑shock, vibration, and reflow solder heat testing.
