2. Understanding Pogo Pin Technology and Design
Core Components and Functionality
A pogo pin consists of four essential components working in harmony:
Barrel: The cylindrical housing that contains the internal mechanisms and provides the mounting interface to the PCB or housing.
Plunger: The spring-loaded contact element that makes physical and electrical connection with the mating surface.
Spring: The internal compression spring that provides constant force to maintain reliable electrical contact throughout the connector's stroke range.
Contact Surfaces: Typically gold-plated over nickel for optimal conductivity, corrosion resistance, and extended wear life.
Working Heights and Stroke Ranges
Understanding the three critical height specifications is essential for proper connector selection:
Free Height: The fully extended, no-load height of the spring when no compression force is applied.
Working Height: The ideal operational height where the spring provides optimal force and the connector operates within its designed parameters.
Maximum Load Height: The fully compressed position where the plunger contacts the end of the barrel, representing the maximum compression limit.
Typical stroke lengths start from 1.2mm, allowing for tolerance in assembly and providing flexibility for misalignment compensation. This stroke capability enables board-to-board spacing as tight as 1mm while accommodating manufacturing variations.
3. Key Performance Specifications to Consider
