Buy Connector Contacts in Bulk | Manufacturer

A connector is the complete assembly — including the housing, shell, and internal components — used to join two electrical circuits together. A contact (or connector contact) is the individual conductive element inside that connector, such as a pin or socket, that actually makes the electrical connection and transfers current or signal. In short, the contact is the functional metal component that lives inside the connector housing.

The two primary types of connector contacts are pins (male contacts) and sockets (female contacts). Pin contacts are conductive metal elements — typically made from brass or stainless steel — that insert into a mating socket to transfer current or signal. Electropin specializes in manufacturing pin contacts, including press-fit, grooved, barbed, hinge, and PCB connector pins, using cold-forming technology for high-precision, high-volume production.

Electropin connector contacts 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 fully REACH and RoHS compliant, making them suitable for regulated industries worldwide without the use of leaded alloys.

Electropin pins are available with four retention features: star, tabs/spline, inscribed square, and flat. 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 the contact is inserted into plastic housings or metal substrates.

Electropin achieves an industry-leading defect rate of just 1 in 600,000,000 pins produced. This is accomplished through proprietary automatic die rolling (cold-forming) technology, which eliminates tool dulling — a common cause of quality variation in traditional machining. The result is consistent, high-precision quality from the very first part to the millionth.

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.

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.
