46 Series DPDT Switch This DPDT switch is two SPDT relays (similar to the DowKey 164 Series) mounted together on a common plate with a single actuating coil. The connectors are all opposite the mounting surface, allowing easy access and flush-mount capability. With excellent RF performance, this low cost dual relay is suitable for most general purpose switching applications. Typical applications for the 46 Series include: • RF and Microwave Communications • Dual-Monitor Video Switching • Magnetic Resonance Imaging Systems • RF and Video Switching DowKey® 46 Series DPDT Switch RF Characteristics Specifications : Operating Voltage: (across temperature range) 12 Vdc (11-14 Vdc) 28 Vdc (24-32 Vdc) Coil Current (Nominal): 12 Vdc 250 mA 28 Vdc 114 mA Operate Time: 20 mS maximum Operating Temperature: 0ºC to +65ºC Mechanical Life, Cycles: 1 x 106 minimum Nominal Weight: 9.5 oz., (270g.)
