1mm (0.039") Pin Header and Socket

1mm pitch (0.039" centreline) micro headers and sockets are available in through hole or SMD. There are a variety of options in the range, including straight and right angle configurations in both single and dual row. Elevated header products are available.

Available in tape & reel, tube and plastic box packaging. For pick and place equipment, we offer caps and film for tape & reel and tube. GCT high temperature 1mm connectors can withstand the solder process up to 280°C (IR Reflow) or 250°C (Wave Solder), with LCP or Nylon 6T and have an operating temperature of -40°C to + 105°C and a current rating of 1 amps per circuit.

All 1mm pitch board to board connectors are fully Reach and RoHS 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.
  • 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.
