What Are Spring Probes Connectors?

Spring probe connectors use a plunger, barrel, and spring system for consistent contact during electronic testing or device interconnection. These connectors, also called pogo pins, maintain reliable electrical pathways even if devices experience micro-movements. Electronics engineers implement spring probes to enable repeated mating cycles and stable signal transmission in test equipment, PCB interfaces, or battery connections.

Manufacturers like Promax in China manufacture spring probes and custom connectors that support industries such as consumer electronics, medical devices, and aerospace. Promax integrates strict material control for plunger and barrel metals, often using brass or beryllium copper with gold-plated finishes to ensure high conductivity and wear resistance. Product designers select spring probe connectors for durability, compact size, and adaptability in high-density layouts.

Spring probe connectors differ from traditional fixed pin connectors because they tolerate mechanical stresses and align easily in blind-mating applications. Engineers prioritize features such as contact resistance below 50mΩ, current ratings from 1A to 15A, and thousands of lifecycle actuations. Battery contacts, charging pins, and test sockets use spring-loaded connectors for safe, repeatable connections. Promax supports low to high-volume orders with quick prototyping, enabling rapid integration of custom spring probe solutions for OEMs and EMS providers.
