Buy Connector Contacts in Bulk | Manufacturer

The three primary connector types are board-to-board (PCB-to-PCB), wire-to-board, and wire-to-wire connectors. Each uses different contact pin designs — such as press-fit, through-hole, or post-insertion pins — to ensure reliable electrical connections. Electropin manufactures contacts compatible with all three connector configurations across automotive, medical, and electronics applications.

Most connectors use solid or press-fit pin contacts made from brass or stainless steel. Solid contact pins offer high conductivity and structural integrity, while press-fit and grooved pin contacts provide secure retention in PCBs and metal housings without soldering. Electropin's cold-formed pins — including barbed, hinge, and PCB connector pins — cover the most common contact requirements.

Electropin connector pins are manufactured from lead-free brass and stainless steel. Lead-free brass offers excellent electrical conductivity and formability, while stainless steel provides superior hardness and corrosion resistance. Both materials are available across the full product range and are fully REACH and RoHS compliant without requiring leaded alloys.

Electropin pins are available with star, tabs/spline, inscribed square, and flat retention features. Star retention can achieve a diameter up to 50% greater than the wire raw material, providing exceptional pull-out resistance. These features prevent rotation and axial displacement after insertion into plastic housings or metal substrates.

Electropin can begin manufacturing and deliver a first batch of cold-formed pins in as little as two weeks from order confirmation, provided raw materials are available. Subsequent batches are delivered on a customer-specified schedule, and production volume can be scaled dramatically to accommodate changing demand without lead-time penalties.

Yes. Electropin offers full DFM (Design for Manufacturing) consultation with experienced engineers who refine pin geometry for optimal cold-forming performance. Custom die molds are created for unique specifications, covering retention features, diameter profiles, and material selection. The collaborative design process ensures first-article accuracy before high-volume production begins.
