1.27mm (.050") Pin Headers and Socket

1.27mm pin header and socket connectors are available in through hole or SMD. Customers may choose from straight or right angle in single and double row configurations. There are numerous special options available, including polarised and keyed connectors.

1.27mm headers and sockets are 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 1.27mm connectors can withstand the solder process up to 280°C (IR Reflow) or 250°C (Wave Solder), with LCP or Nylon 6T, have an operating temperature of -40°C to + 105°C with a current rating of 1 amp per circuit.

  • 1.27 mm (.050") male and female pin headers and sockets
  • SMD and Through Hole
  • Customer specifiable pin lengths and spacer heights
  • Choice of pin material and plating
  • Female headers available with a choice of insulator height
All 1.27 mm pin headers and sockets are 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.

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.

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.

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.

Header 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.

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.

Polarisation

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.
