Telecom Contact Pins | High Reliability Manufacturing

Electropin's automatic die rolling process achieves an industry-leading defect rate of just 1 in 600,000,000 pins. Because dies do not dullen during cold-forming, dimensional accuracy remains consistent from the very first pin to the millionth pin, unlike machined parts where tool wear degrades tolerances over time.

Using proprietary automatic die rolling technology, Electropin produces up to 5 custom connector pins per second. This high-speed output allows for rapid prototyping and large-volume production runs, with first-batch delivery in as little as two weeks when raw materials are available.

Yes. All Electropin contact pins are manufactured using lead-free materials, which fully eliminates regulatory exposure under both REACH and RoHS directives. Unlike conventional machined connector pins that rely on leaded brass for machinability, cold-formed die-rolled pins do not require lead additives at any stage.

Electropin offers four primary retention feature types: Star, Tabs/Spline, Inscribed Square, and Flat. These features provide anti-rotation and high pull-out resistance for press-fit into metal, post-insertion into molded plastic, and through-hole PCB mounting applications. The star feature can expand pin diameter by up to 50% beyond the wire diameter.

Electropin contact pins support three primary mounting methods: press-fit into metal housings, through-hole PCB mounting for circuit board assemblies, and post-insertion into molded plastic parts. High-speed automation-compatible designs are also available for grooved pin configurations used in high-volume production environments.

Yes. Electropin offers full Design for Manufacturing (DFM) consultation, custom die creation, and collaborative engineering support to refine pin geometry for optimal production. Custom dies are created to match your specifications, and first production batches can typically be delivered in as little as two weeks after design approval.
