Rugged D-Sub with Twinax/Quadrax contacts

100 ohm quadrax and/or differential pair twinax

Smiths Interconnect’s twinax/quadrax D-Sub connectors provide robust high-speed performance compatible with existing qualified rugged D-Sub connectors.

Features & Benefits

High impedance D-Sub connectors are designed to ground the outer shield of a twinax or quadrax contact directly to the shell of the connector. A multi-finger ground spring fixed around the shell provides a multi-point contact engagement that affords superior EMI shielding. The end result is an extremely low contact resistance when measured from the contact outer body to the connector flange, ensuring minimal RF noise and high durability of over 500 mating cycles. Our D-Sub meets and surpasses all requirements of MIL-STD-202 for shock and vibration, and is offered with 100 ohm quadrax and/or differential pair twinax contacts. To ensure that the correct high speed connectors are mated to address specific wiring requirements and keying combinations, a keyed jack post was incorporated into the design. The six-positioned keyed jack post allows for 36 possible keying combinations assuring that the correct high speed rugged D-sub plug is mated to the correct high speed receptacle.
