Medical Device Connector Pins | Lead-Free Cold-Formed | Manufacturer

Electropin offers medical device connector pins in lead-free brass and stainless steel as standard material options. Both materials are suitable for demanding medical applications, with stainless steel providing greater hardness and corrosion resistance and lead-free brass offering excellent electrical conductivity and formability for precision contact applications.

Electropin achieves an industry-leading defect rate of just 1 in 600,000,000 pins. This exceptional accuracy is a direct result of the automatic die rolling (cold-forming) process, which does not involve cutting or heat. Because the dies do not dull over time, quality remains consistent from the very first pin to the millionth pin in a production run.

Electropin can begin manufacturing and deliver a first batch of cold-formed connector pins in as little as two weeks when raw materials are available. Subsequent batches are delivered on the customer-specified timeline, and production can be dramatically scaled up to accommodate increases in demand without compromising quality or lead times.

Electropin offers four retention feature options: Star, Tabs (Spline), Inscribed Square, and Flat. The Star feature provides the greatest diameter expansion — up to 50% greater than the wire raw material diameter — offering strong press-fit retention in both metal and molded plastic assemblies used across medical device applications.

Electropin's connector pins support three primary mounting methods: press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic parts. This versatility makes them suitable for a wide range of medical device connector assemblies, from circuit board integration to overmolded plastic housing applications.

Yes. Electropin provides full Design for Manufacturing (DFM) consultation, custom pin design refinement, and collaborative engineering support. With over 35 years of experience, the team works directly with customers to optimize pin geometry, material selection, and retention features for specific medical device performance requirements before production begins.
