High Current Pogo Pin Connector

How to Choose the Right High Current Pogo Pin Connector

A high-current pogo pin connector carries power or charging current through a spring contact. The right connector depends on your peak current, pin count, spring force, and plating. Use the steps below to spec it.

1. Set the current rating for your power path. High-current connectors carry 3A to 15A per pin, with peaks to 12A on some builds. Match the rating to your peak load and leave headroom for in-rush. We widen the barrel and plating when your design needs more.
2. Set the pin count for your power map. Our high-current connectors run from 2 to 8 pins. Pick the count that splits your load across enough contacts. Send your power map and we’ll match the layout.
3. Match the connector length to your footprint. These connectors run 4.7 mm to 36 mm long and 2.5 mm to 10 mm wide. Pick a body that fits the contact area without crowding nearby parts. Share your footprint for a fit check.
4. Pick the spring force for firm power contact. Spring force runs 50 gf to 870 gf across the range. Higher force drives the contact firm to keep resistance and heat low under load. We tune force to protect the mating surface.
5. Set the working height for reliable compression. Working height ranges from 4.7 mm to 14.9 mm. Spec the height where the pins hold firm contact without bottoming out. We’ll model the travel against your mating gap.
6. Choose the plating for low resistance under load. Plating spans Au 3u to Au 30u for low, stable resistance. On power contacts, low resistance limits loss and heat. Thicker Gold suits high-cycle charging docks.
7. Not sure which connector fits? Talk to our engineers. Send us your peak current, pin count, and mating gap. We’ll match a catalog connector or design a custom high-current pogo pin connector. Free samples ship within two weeks.
