Probe Pin Types for Testing | OEM Supplier

Electropin offers pins in lead-free brass and stainless steel as standard material options, as well as other metals depending on the application. Lead-free materials eliminate REACH and RoHS compliance concerns without requiring the use of leaded brass common in machined parts.

Available retention features include Star, Tabs (Spline), Inscribed Square, and Flat designs. These features provide anti-rotation and high retention strength for applications in press-fit metal assemblies, through-hole PCB mounting, and post-insertion into molded plastic parts.

Electropin pins support press-fit into metal, through-hole PCB mounting, post-insertion into molded plastic, and high-speed automation applications. Specific mounting compatibility varies by pin type — barbed, grooved, and hinge pin designs each offer distinct installation advantages for specific assemblies.

When raw materials are available, Electropin can begin manufacturing and deliver the first batch of cold-formed pins in as little as two weeks. Subsequent batches are delivered on a customer-specified timeline, and production volume can be scaled dramatically as requirements change.

Yes. All Electropin pins are manufactured using lead-free materials, which eliminates REACH and RoHS regulatory concerns entirely. Unlike machined parts that typically require leaded brass to achieve tight tolerances, Electropin's cold-forming process achieves high precision without hazardous materials.

Electropin's automatic die rolling process achieves an industry-leading defect rate of just 1 in 600,000,000 pins. Because the cold-forming tools do not dull over time, quality remains consistent from the very first pin to the one-millionth pin in a production run.
