Mill-Max Manufacturing Corp., Inc. has announced the development of new spring-loaded pins delivering high-current carrying capacity in a small form factor. They are ideal for charging applications and directly delivering power via cable or board-to-board interconnects.
The reduced size makes them attractive for use in dense, low-profile packaging designs. This new product offering is available in three different termination styles: surface mount, through-hole, and solder cup.
All three meet two of the most demanding requirements designers carrying capacity of 6 amps (@ 30° C rise), with an above-board height of just .204″ (5.2 mm) for the surface-mount and through-hole versions.
The solder cup version has a total length of .374″ (9,5 mm), all have a maximum diameter of .083″ (2,1 mm). The 6-amp rating is based on the current-temperature derating curve. Mill-Max designed and constructed these spring-loaded pins to have more mass and greater contact surface area between the components.
These design features result in lower overall bulk resistance, with more efficient heat dissipation and electrical conductivity — all while delivering smooth operation throughout the stroke of the pin.
Other attributes include:
- Gold-plating on all components
- Cycle-life rating of 1,000,000 at half stroke
- Contact resistance of 20m-ohms (max) and spring force of 60 grams at mid stroke (.0275″, .7 mm)
These spring-loaded contacts are an excellent choice for docking stations, quick connects, and blind mating applications, as well as in board-to- board and cable connectors.
