Cannon Combo D Applications Combination D Subminiature connectors for the advan- Video Coaxial Transmission (75 ) tages of an industry standard shield I/O interconnect, with RF and Telecom Transmission (50 ) the flexibility of a customized special, designed for any Power interconnects (Up to 40 A) application. Product Features Standard and European Footprints This connector system is ideal for applications that require /50 Coaxial or High Power contacts (One Pre-installed 75 optimization of space while improving overall shielding. Part Number) Combo D accomplishes this by combining multiple Vertical Standoffs or 90 Brackets interconnect types into one fully shielded product, 90 or Straight PCB decreasing the number I/O interfaces and reducing the PC Boards up to 3,2 (.125) Thick possibility of EMI/RFI leakage.
