Buy D-Sub Connector Contacts in Bulk | Manufacturer

Standard D-sub contacts come in three main size classes: size 20 (standard), size 22D (high-density), and size 23 (double-density). Pin diameter, length, and retention feature dimensions vary by connector series and mounting method. Electropin produces custom contact pins to your exact dimensional specifications using automatic die rolling, accommodating a wide range of sizes across these classes.

Electropin manufactures connector contacts from lead-free materials including soft brass and hard stainless steel. Lead-free formulations eliminate the need for leaded brass that machined parts often require, ensuring full REACH and RoHS compliance without additional processing steps or compliance risk for your product.

Electropin offers four retention feature types: Star, Tabs/Spline, Inscribed Square, and Flat. The star feature can expand the pin's diameter by up to 50% beyond the raw wire diameter, providing strong mechanical retention. These features prevent rotation and ensure secure seating in plastic housings and metal substrates.

Electropin's D-sub connector contacts support three primary mounting methods: press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic housings. This versatility makes them suitable for a broad range of connector assemblies across automotive, medical, electronics, and industrial applications.

Yes. Because Electropin uses a cold-forming process rather than machining, lead-free materials can be used without compromising structural integrity. This eliminates the need for leaded brass entirely, making all lead-free pin variants fully compliant with both REACH and RoHS regulations — removing compliance risk from your supply chain.

Electropin can begin manufacturing within the agreed project timeline and deliver a first batch of cold-formed pins in as little as two weeks when raw materials are available. Subsequent batches are delivered on a customer-specified schedule, and production output can be rapidly scaled up to 5 pins per second to meet increased volume demands.
