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.
