2.0mm SMD 3A spring loaded connector components engineered by CTP deliver exceptional reliability for high-density, automated surface mount (SMT) applications. Specifically designed with a flat-bottomed barrel, this connector is optimized for seamless robotic placement, ensuring superior stability and simplified mounting processes on your printed circuit boards.
As a globally trusted source manufacturer, CTP has perfected the internal architecture of these spring-loaded contacts. Each pin consists of a custom-machined turning barrel, a cutting-edge plunger, and a resilient compression spring. The meticulously crimped barrel edge securely retains the plunger, while the internal SUS spring delivers a calibrated contact force of 70g. This mechanism guarantees a stable, uninterrupted electrical connection between the plunger and the mating joint, significantly minimizing signal impedance for reliable 3A continuous power transmission.
Partnering with CTP means integrating 14 years of specialized manufacturing experience directly into your supply chain. We excel in high-current connections, ultra-high life cycles, low impedance, and superior corrosion resistance:
