| 7000 Series/High Reliability Reed Relays RELIABILITY REED RELAYS H IGH RELIABILITY REED RELAYS The 7000 Series is ideally suited to the needs of Instrumentation, Data Acquisition, Process Control, Telecommunications and General Purpose requirements. The specification tables allow you to select the appropriate relay for your particular application. These models are specifically designed for high quality and reliability with versatile switching capabilities and contact forms. If your requirements differ, please consult your local representative or Coto's Factory to discuss a custom reed relay. 7000 SERIES FEATURES SERIES FEATURES u u u u u u u u Versatile, multi-pole contact forms. (Form A, B, and C) (For all models listed see pgs. 20-21) Wide range of switching capabilities; Low level, High Voltage, Hg wet. Hermetically sealed contacts for long life and high reliability. High speed switching compared to electromechanical relays. Potted in metal shell - Magnetic Shield. Optional Electrostatic Shield for reducing capacitive coupling. PCB mounting versatility - 1.0" x 0.100" grid. Optional coil suppression diode offered to protect coil drivers. * * Height of Model 7003-5193 is .480 (12.2) Dimensions in Inches (Millimeters) See pages 20-21 for Schematic Diagrams & Coil Data Corresponding to Package Widths 2 18 Catch Us on the Web! www.cotorelay.com E-Mail us: sales@cotorelay.com 7000 Series/High Reliability Reed Relays Parameters CONTACT RATINGS Switching Voltage Switching Current Carry Current Contact Rating Life Expectancy-Typical 1 Static Contact Resistance (max. init.)
