Buy Electrical Connector Pins & Terminals in Bulk | Manufacturer

Electrical pins are commonly called connector pins, contact pins, or terminal pins. Depending on their function or form, they may also be referred to as PCB pins, press-fit contacts, solid contact pins, or electrical terminals. In the connector industry, the terms 'pin' and 'contact' are often used interchangeably to describe the male element of an electrical connector assembly.

Connector pin size is typically measured by wire diameter (the base diameter of the raw material), overall length, and the diameter of any retention features such as a star or spline. For die-rolled pins, the star feature can achieve a diameter up to 50% greater than the wire diameter. Accurate measurement requires calipers or optical comparators, and Electropin's engineers can assist with design specification and DFM review.

Electropin produces connector pins from lead-free brass, stainless steel, and other compatible metals. All materials are selected to eliminate REACH and RoHS compliance concerns, meaning no leaded brass is required — unlike traditionally machined connector pins. Material choice depends on the application's conductivity, hardness, and corrosion resistance requirements.

Electropin connector pins support three primary mounting methods: press-fit into metal substrates, through-hole PCB mounting for circuit board assembly, and post-insertion into molded plastic parts. Many pin types also support high-speed automation applications where pins slide down tracks without requiring a specific orientation during assembly.

Yes. All Electropin connector pins are manufactured lead-free, which fully eliminates REACH and RoHS compliance concerns. Unlike machined parts that often require leaded brass for machinability, Electropin's cold-forming process works with lead-free materials, simplifying regulatory compliance for customers in the EU and other regulated markets.

Electropin can begin manufacturing custom connector pins in as little as two weeks from design confirmation, provided raw materials are available. There is no fixed minimum order quantity published — pricing and volumes are available on request. Production can be dramatically scaled up to accommodate changing demand, and batches are delivered on a customer-specified timeline.
