1.27mm (0.050") PCB Connectors

Pin headers and female socket connectors in 1.27mm (.050") pitch offer 2 to 50 contacts single in line and 4 to 100 contacts dual in line. Capable of 1.0A per circuit with a dielectric withstanding voltage of 300V AC and operating temperature range of -40°C to 105°C. Mated board to board connector pairs offer 100 insertion cycles durability.

Available in single and dual row in through hole (TH) and surface mount (SMT). Headers and sockets available in both vertical and horizontal orientation.

Pin headers are available in SMT or thru hole with vertical and horizontal orientation. Pin headers allow a customizable pin length, with two options of square pin size 0.40mm (.016") or 0.46mm (.018"), check drawings for details including appropriate mating halves. Elevated PCB headers offer parallel PCB stacking solutions up to 36mm (1.417") between boards.

U shaped pin headers are available, suitable for co-planar PCB applications, either to soldering direct or plug to two vertical sockets.

PCB sockets are available in SMT or thru hole in vertical and horizontal orientations. Sockets accept either 0.40mm (.016") or 0.46mm (.018") square pin headers, check drawings for mating part details.

SMT receptacles offer dual entry PCB mating options: Pin headers are mated with receptacles from above to achieve standard parallel PCB mating. In bottom entry mode holes are drilled in the PCB and the header pins enter the socket from below via the underside of the PCB.
Bottom entry offers alternative design solutions, for example achieving a very low parallel PCB stacking height by mounting the socket on top of the PCB, the stack height is the header insulator, as low as 1.00mm (.039"). Alternatively bottom entry allows connection of three PCB’s using a pass thru technique, where a long header pin mates with two PCB sockets, passing all the way through the middle socket.

A range of shrouded headers with keyed cutouts and sockets with bumps offer polarisation which ensures connectors may only be plugged together in the correct orientation. Shrouded parts also provide protection from shorting, especially on the shrouded elevated pin header, where pins are normally exposed. For parallel PCB stacking there is a stacking elevated shrouded header.

Tube or Tape and reel packaging (with or without film or caps) for pick and place assembly, is available on all surface mount connectors.

All GradConn board to board connectors are RoHS compliant and suitable for high temperature processing, see downloadable drawings and product specification for more details.
