Solutions | End-to-End Pins


Our unique swaging process guarantees the highest quality End-to-End contact pins for reliable automatic insertion. Tandem Pin® brand End-to-End contact pins have precision tips for lower insertion force and more dependable connections. Consistent length and a smooth transition between the pin tip and body assure accurate cut-off and cleaner insertion.

  • Consistent contact pin length (pitch) for reliable pin insertion
  • Inconsistent contact pin length causes insertion downtime
  • Smooth transition between tip and body for lower insertion and mating forces
  • Pyramid-shaped stamped tips with abrupt transitions and burrs increase insertion and mating forces
  • Precise cut-offs prevent scraping of mating contact surfaces and ensure a more reliable connection
  • Sharp cut-off stubs scrape off plating on mating connector and lead to poor contact reliability
  • Smooth transitions mean less scraping and cleaner PCB assembly
  • Abrupt transitions mean more scraping and debris on the PCB
  • Precision level layer winding makes pay-off easy
  • Uneven winding leads to tangles, coil breakage and machine down-time
  • Custom packaging to ensure your contact pins arrive safely
  • Standard packaging allows product to shift during shipping

 Our solutions don't end there; we also have a variety of custom assembly options.
