Board to Board Connector

Board to board connector products are available in 0.8x1.2mm (.031"x.047"), 1mm (.039"), 1.27mm (.050"), 2mm (.079") and 2.54mm (.100") pitch ranges, with options of surface mount or through hole mount types.

Parts are offered in straight, right angle or U shaped configurations allowing a wide variety of printed circuit board design options.

Receptacles and plugs may be chosen in single, dual, triple or quad rows and both types of product have elevated options to allow stacking design flexibility.

Headers and sockets offer customer specifiable pin lengths, varying profile heights. Choose your number of contacts from two to more than one hundred. Surface mount parts have options for optional locating pegs.

Technical drawings, product specifications and 3D models are available for download or request for all parts.

Board to board connector products are fully RoHS and Reach compliant.

  • Pitch
    Distance between connector pin centrelines. For dual row products pitch defines distance between both pins and rows. Note 0.8 x 1.2mm (0.31” x .047”) is the exception to this rule.
  • Gender
    Male headers with exposed pins and female sockets with insulated non-exposed contacts.
  • Mount Type
    Termination method of soldering connector onto PCB.
  • PCB Orientation
    Defines the orientation which a connector sits on the PCB. Vertical (straight) is 90° to the PCB, right angle (horizontal) is 180° to the PCB. Use the appropriate mating connector pairs for parallel, co-planar and right angle PCB mating configuration.
  • Number Of Rows
    Defines PCB connector number of rows. GCT offer single in line (SIL), dual in line (DIL), triple in line (three rows) and quad in line (four rows) options.
  • Elevated?
    Products which achieve a greater space between PCB’s, normally used in parallel PCB stacking applications to achieve a desired height. Elevated headers normally have two insulators, while elevated sockets use an insulator block and modular insulator extenders.
  • Socket Entry Type
    Searches female connectors only and displays whether header pins may enter from above (top entry), from below with appropriate holes in PCB (bottom entry) or from both above and below (dual entry). See drawings for details of PCB layouts required for bottom entry connector mating.
  • Socket Contact Type
    Socket contact type", "Searches female connectors only. Two contact types: ‘Leaf Spring’ and ‘Tuning Fork’, both offer two points of contact with mating header pins. ‘Tuning Fork’ is the lower cost option, with higher insertion and extraction force, suitable only for top entry applications. ‘Leaf Spring’ is lower force contact and suitable for top, bottom & dual entry applications. For higher number of mating cycles choose ‘Leaf Spring’.
  • Locating Peg
    Plastic locating pegs to hold the connector in place during solder process and may provide extra strength post soldering. Also known as plastic post.
  • Profile
    The profile of connectors above the PCB. Vertical connectors denote the stacking profile in parallel PCB applications, right angle connectors denotes height above the PCB.
  • Polarisation/Shrouded
    Polarisation allows connectors to be plugged together in only the correct mating orientation. Achieved by a polarisation cutout or ‘key’ on PCB headers and raised polarisation bump on female connectors. Select both ‘key’ and ‘bump’ to view all polarised parts.
    • Polarisation bump
    • Polarisation key
    • Yes2
  • Insulator Colour
    Standard board to board connector range is black, white insulators used for White Lite range for Solid State Lighting (SSL) applications.
  • Header Square Pin Size
    Displays the size of the header square pin/post, as connector pitch reduces sq. post size reduces too, one reason for lower current carrying capability of smaller pitch PCB connectors. Note: Two options in 1.27mm (.050”) pitch. Female sockets clearly state which header square pin size they mate with.
