The most cost-effective, high-performance contact

The H-Pin® provides the mechanical and electrical benefits of a spring probe pin with the cost savings and manufacturing process control of a fully automated stamping and assembly manufacturing process.
The H-Pin is a stamped spring probe pin made from the assembly of three components: two beryllium copper stampings and one stainless steel would spring.

H Pin Technology

Each of these components comes from a fully automated, high -volume manufacturing process.
The H-Pin unique design and its equally special assembly process result in an electrical contact with superior performance, at the same time allowing for an affordable solution for new connector designs.

  • The beryllium copper stampings provide reliable and stable conductivity for flat resistance curves, -great current per pin capacity and fast signal speed.
  • The stainless steel spring provides mechanical cycle life, shock and vibration endurance and operating temperature well above 220°C.

The H-Pin manufacturing process allows to reduce costs without compromising design. It also provides the peace of mind of quality assurance and reliability that only comes from a fully automated and redundant inspection process.


A new approach to pin design, manufacturing, packaging, delivery and price that gives you a high performance contact pin at the lowest cost.

The H-Pin is a stamped spring probe with the mechanical, electrical and thermal performance of a spring probe, and the ease of use and high volume manufacturability of a stamped contact. The H-Pin serves applications without the typical compromises that are generally required when considering cost versus performance.

H-PIN Highlights

Excellent mechanical and electrical performance.

Utilizing high volume BeCu stamping technology, combined with a stainless steel spring for mechanical travel, the H-Pin has a working range up to 0.70 mm with a flat spring rate and can be utilized up to 15GHz with -1.0dB loss, carry up to 4 amps of current and withstand temperatures up to 200°C.
