Connector Pins Manufacturer in Minnesota

Pin connectors go by several names depending on their application and design, including contact pins, connector pins, terminal pins, and electrical pins. Specific types include PCB connector pins, press-fit pins, barbed pins, grooved pins, knurled pins, hinge pins, and dowel pins. The terminology typically reflects the pin's mounting method, retention feature, or primary application.

Electropin produces connector pins primarily in lead-free brass and stainless steel. Lead-free brass offers excellent conductivity and cost-efficiency, while stainless steel provides superior hardness and corrosion resistance. Both materials eliminate REACH and RoHS compliance concerns, making them ideal for regulated industries such as automotive, medical devices, and consumer electronics.

Electropin offers four retention features: Star, Tabs/Spline, Inscribed Square, and Flat. The Star feature can expand pin diameter by approximately 50% over the wire raw material diameter, providing exceptional press-fit holding strength. Tabs/Spline and Inscribed Square options deliver strong anti-rotation performance, while the Flat feature suits applications requiring minimal interference fits.

Electropin connector pins support three primary mounting methods: Press-Fit into Metal, Through-Hole PCB Mounting, and Post-Insertion into Plastic. This versatility allows the same cold-forming manufacturing platform to serve PCB assembly, molded plastic housing insertion, and direct metal-to-metal press-fit applications across automotive, medical, and electronics sectors.

Yes. Electropin's lead-free manufacturing process fully eliminates the compliance burden associated with REACH and RoHS regulations. Unlike machined parts that often require leaded brass, Electropin's cold-formed pins are produced without lead, meaning customers in regulated industries — including automotive, medical, and consumer electronics — do not need to manage hazardous substance declarations for these components.

Electropin can begin manufacturing custom connector pins and deliver a first batch in as little as two weeks when raw materials are available. Beyond the initial delivery, production batches are scheduled on customer-specified timelines. The high-speed process — producing up to 5 pins per second — also allows production volume to be scaled dramatically when demand increases.
