Compliant Pins | Cold-Formed Press-Fit Precision | Manufacturer

A compliant PIN password refers to a personal identification number that meets defined security policies — such as minimum length, character complexity, or non-reuse rules. This is unrelated to compliant connector pins. If you are looking for press-fit electrical connector pins, Electropin manufactures cold-formed compliant pins for automotive, medical, and electronics applications.

In electronics manufacturing, PIN stands for Pin Insert Number or simply refers to a conductive terminal used to make electrical contact. In security contexts, PIN means Personal Identification Number. In Electropin's context, a pin is a precision-manufactured metal contact — cold-formed from brass or stainless steel — used in connectors across automotive, PCB, medical, and industrial applications.

Electropin's compliant pins are manufactured from lead-free brass and stainless steel. All materials are lead-free by design, which eliminates REACH and RoHS compliance concerns without requiring any additional treatment or substitution — a significant advantage over traditionally machined pins that typically use leaded brass.

Electropin offers four primary retention features: Star, Tabs/Spline, Inscribed Square, and Flat. The star feature can achieve a diameter up to 50% greater than the original wire diameter, providing exceptional retention strength. These features support anti-rotation and high pull-out resistance for press-fit into metal, PCB through-hole, and post-insertion into plastic applications.

Electropin can begin manufacturing custom compliant pins and deliver the first batch in as little as two weeks when raw materials are available. Subsequent production batches are delivered on a customer-specified timeline, and production volume can be dramatically scaled up as demand changes — making Electropin suitable for both prototyping and high-volume production runs.

Electropin's cold-formed compliant pins serve a wide range of industries including automotive connectors, farm equipment electrical systems, computer and consumer electronics, medical device connectors, and PCB/circuit board assembly. Their lead-free, high-precision pins meet the demanding quality and regulatory standards required across all of these sectors.
