From July 1st, 2024, GradConn & GCT (both Aloco Group companies) will merge under the GCT brand. The planned completion date is Q1 2025.
All current GradConn products will remain available under their existing part codes for the foreseeable future. Please contact us if you need to re-order.
Please use one of the links below to continue your journey.
Following the merger with GCT your choice of Board-to-Board connectors is now even wider.
GradConn B2B connectors will remain available under the same part code for existing projects. Please contact us if you need to re-order.
Following the merger with GCT your choice of SIM connectors is now even wider.
GradConn SIM connectors will remain available under the same part code for existing projects. Please contact us if you need to re-order.
Pin headers and female socket connectors in 2.54mm, pin spacing is 2.54mm (.100") between pins and rows.
Pin headers and female socket connectors in 2 to 40 contacts single in line, 4 to 100 contacts dual in line and 9 to 120 contacts in triple in line. Capable of 3.0A per circuit with a dielectric withstanding voltage of 600V 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, dual row and triple 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 customisable pin length with a square pin size 0.64mm (.025"). Elevated PCB headers offer parallel PCB stacking solutions up to 41mm (1.614") 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.
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 1.50mm (.059"). 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. Available in vertical and horizontal orientation For parallel PCB stacking applications there is a stacking elevated shrouded header.
Options for perfect co-planar PCB connection in thru hole, SMT in single and dual row. See the planar mating guide for more information.
Tube or Tape and reel packaging (with or without film or caps) for pick and place assembly, is available on all surface mount 2.54mm 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.
