Frequently Asked Questions
Q: What are SMT pogo pin connectors used for?
A: SMT pogo pin connectors (spring-loaded contact needles) are used in PCB testing, battery contact points, programming jigs, charging interfaces, and prototype electronics. Their spring-loaded design ensures consistent electrical contact even on uneven or slightly misaligned surfaces.
Q: What size pogo pin do I need for my project?
A: The right pogo pin size depends on the spacing and footprint of your PCB or battery contact. This set offers sizes from 2.0mm up to 7mm, covering a wide range of standard SMT and through-hole applications. Refer to your PCB design files or component datasheet for the exact pitch and stroke requirements.
Q: What is the current capacity of these pogo pins?
A: Each pogo pin supports a continuous current of 1A and an instantaneous peak current of 3A, with a contact resistance of less than 30 mΩ — making them well-suited for low-power signal testing and battery contact applications.
Q: Are these pogo pins compatible with standard PCB testing equipment?
A: Yes. These brass spring-loaded contact needles are designed to work with standard PCB test fixtures and programming jigs. Always verify the pin diameter and travel length against your equipment's specifications before use.
