Because of its increased height, the 9092 model allows for incorporation of 2 Form A switches in the same board space. These miniature SIP relays utilize 10W switch technology, making these SIP relays ideal for use in ATE applications and other high reliability test, measurement and telecommunications applications where high board density and long life are key requirements. ## **9091 & 9092 Series Features** - u 9091 is a 10W SIP relay measuring .615” x .150” x .275” - u 9092 is a 10W SIP relay measuring .600” x .150” x .350” - u Magnetic shield – reduces interaction - u Optional coil suppression diode protects coil drive circuits - u UL File #E67117 - Contact factory for details - u High insulation resistance, 10[12] Ω minimum - u High speed switching - u Molded thermoset body on integral lead frame design - u High reliability, hermetically sealed contacts for long life - u RoHS compliant **DIMENSIONS** _in Inches (Millimeters)_ Model 9091 Model 9092 **==> picture [492 x 138] intentionally omitted <==** **----- Start of picture text -----**
