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.
GradConn Ltd are committed to supply products that meet the requirements of the Restriction of Hazardous Substances directive (2011/65/EU & 2015 /863/EU), each drawing is clearly marked in the top right corner to show the products are compliant. Certification is available see below.
Under RoHS Decabromodiphenyl Ether (Deca BDE) is restricted (at levels of >1000ppm) from Electrical and Electronic equipment as of 30th June 2008. GradConn parts adhere to this restriction.
Gradconn has reviewed its product range; currently we do not have any items with a chemical content that necessitates registration under the REACH Directive (EC)1907/2006). A copy of our REACH certifcate is available, see below.
GradConn understand the change to production processes brought about by RoHS compliance within reflow and wave solder processes, as such we offer a variety of different insulator styles to suit customer's requirements.
SMT connectors: Insulators are produced in either Nylon 6T, Nylon46 or LCP (Liquid crystal polymer), which are all capable of withstanding the increased temperatures of lead free solder processes.
Through hole connectors: Insulators are produced in Nylon 6T as standard, this is suitable for withstanding high temperature wave and reflow RoHS solder processes.
PBT is not suitable for wave solder process (RoHS and Non-RoHS), and as such is not suitable for new designs, as such Grad Conn will not quote PBT insulator material for new enquiries but continue to support PBT as a legacy product for existing customers.
Specify through hole insulator material using the final two digits of part number. These digits left blank specify PBT (see example below).
