9104 Series/High Voltage SIP Reed Relays

Molded SIP relays are the industry standard when high reliability and consistent performance are desired in a compact package. The 9104 Series adds high voltage switching capability and high voltage standoff capability to a SIP relay package. These high voltage, high performance relays are ideally suited for Automatic Test Equipment, Instrumentation, Battery Management, Solar and Process Control applications where voltage isolation is a key design requirement.  Download Datasheet
