Connector Pins Manufacturer in California

Electropin's connector pins serve the automotive, medical device, farm equipment, computer and electronics, and circuit board industries. They are also used for post-insertion into molded plastic parts and press-fit into metal components, making them suitable for a wide range of assembly and connector applications.

Electropin achieves an industry-leading defect rate of just 1 in 600,000,000 pins. This is made possible by the automatic die rolling (cold-forming) process, which uses dies that do not dull over time, ensuring every pin — from the first to the millionth — meets the same precise specifications consistently throughout the production run.

Yes. Electropin manufactures lead-free connector pins in brass and stainless steel, which eliminates the need for leaded brass entirely. Unlike machined parts that often require lead additives for machinability, Electropin's cold-forming process achieves full REACH and RoHS compliance without compromising material strength or pin performance.

Electropin's automatic die rolling technology produces up to 5 custom connector pins per second. This high-speed production capability means the first batch can be delivered in as little as two weeks from order confirmation, and production volume can be dramatically scaled up to meet changing customer demand without retooling delays.

Electropin offers four primary retention feature options: Star, Tabs (Spline), Inscribed Square, and Flat. The star feature can achieve a diameter approximately 50% greater than the wire raw material, providing high retention strength. These features support anti-rotation and secure press-fit or post-insertion mounting in plastic and metal assemblies.

Connector pins are available in lead-free brass, stainless steel, and other metals depending on application requirements. Soft lead-free brass is well-suited for standard connector applications, while hard stainless steel is chosen for applications demanding higher strength and corrosion resistance, such as medical devices and harsh-environment industrial connectors.
