2.54mm pitch 4 pin 3a solder cup type spring loaded pogo pin connector components engineered by CTP provide a highly efficient and exceptionally reliable wire-to-board solution for demanding electronic applications. Specifically designed with a premium solder cup termination, this component is highly applicable to cable ends, ensuring effortless wiring and incredibly secure welding for continuous power and signal transmission.
Moving beyond standard configurations, CTP provides comprehensive customization services to meet your specialized engineering needs in the pogo pin connector field. The highly precise internal architecture consists of a custom-machined turning barrel, a cutting-edge plunger, and a robust compression spring. The carefully crimped barrel edge securely retains the plunger, while the internal SUS spring delivers a calibrated contact force of 70g. This mechanism guarantees a flawless, uninterrupted electrical connection between the plunger and the mating joint, significantly reducing signal loss.
Partnering with CTP means integrating 15 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:
