Board to board high speed data transfer

Matched Impedance Differential Pair Twinax & Quadrax

Smiths Connectors has taken the standard housing configuration of the P1 & P3 mounting dimensions while incorporating true differential pair contacts within the P1 & P3 dimensional constraints. Data sampling rates exceeding 2 Gbits/second can be driven via matched impedance differential pair interconnections for board-to-board high speed data transfer as well as blind mate I/O plug in modular applications. Smiths Connectors P1 connector housing contains 21 position true differential pair blind mate contacts allowing board designers to carry high density differential pair signals from the LRU via motherboard to daughter-card plug in modules with a single connector P1 type housing. This allows for the use of standard VME bus architecture cages for high speed fibre channel connection.

Rugged D-Sub Quadrax/Twinax 100 Ohm
Designed to ground the outer shield of a twinax or quadrax contact directly to the shell of the connector

A multi-finger ground spring, fixedaround the shell provides a multi-point contact engagement for superior EMI shielding

Low RF noise and high durability of up to 1,000 mating cycles

Offered with 100 ohm quadrax and/or differential pair twinax contacts

Size 10 contacts are 30% smaller package size for tight space constraints

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 up to 1,000 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.
