2 Pin Spring Loaded Connector Catalog

2 pin connectors, also known as 2 pin electrical connectors or 2 pin spring loaded connector, are primarily used to create stable and reliable electrical or signal pathways between two components. They provide secure mating, consistent conductivity, and dependable performance across a wide range of electronic and power transmission applications.

With advanced technology and expert craftsmanship, we create durable, high performance custom pogo pin connector tailored to each project’s needs. 

What is 2 point pogo pin connector

2 point pogo pin connector is a compact, spring loaded contact module containing two independent conductive pins in a single housing. Each pin comprises a movable plunger, an internal compression spring, and a surrounding barrel; together they form repeatable, low profile electrical contacts that engage by axial compression rather than rigid mechanical mating. Because each pin compensates for tolerance, misalignment, and vibration, two pin modules are widely used for board to board interfaces, charging docks, test fixtures, and removable modules requiring frequent mating cycles. They support signal, ground, or power duties depending on size and plating, and are offered in through hole, SMD, and hybrid mounting styles to suit assembly methods.

How to install 2 point pogo pins connector

Installation depends on mounting style but follows common best practices. For SMD variants, design the PCB land pattern to vendor recommendations, apply solder paste, place the pogo module with pick and place (or carefully by hand), then reflow using a profile compatible with the connector’s plating and polymer base. For DIP/through hole types, insert tails into plated holes and secure by wave or selective soldering; some designs also use plastic bases or solder cups for extra mechanical retention. Leave adequate keep out for full compression travel and test engagement height. Always inspect solder joints, alignment, and run electrical continuity/force checks after assembly.

2 pin pogo connector material & parts

A typical 2 pin pogo connector contains three core components per pin: plunger (movable contact), compression spring, and barrel/body. Conductive elements are usually brass or copper alloys for good conductivity and mechanical strength; springs are commonly stainless steel or music grade spring steel to maintain consistent force and long life. Contact surfaces are frequently plated with nickel plus a thin gold flash to reduce oxidation and achieve stable low resistance. The housing or base is made from high temperature plastics or metal to survive reflow or wave soldering when applicable. Plating thickness, alloy selection, and spring specs are chosen to balance current rating, cycle life, and contact resistance

dip pogo pins internal structures

2 pin spring loaded connector Internal structures

Internally each pin slides within a precision machined barrel and is guided by small clearances and features that keep the plunger centered. The compression spring sits between the barrel and plunger, providing a controlled contact force through the working stroke. Manufacturers use several internal geometries simple bevels, ball tip or copper ball interfaces, and inner hole guide features to reduce friction, stabilize lateral movement, and improve electrical contact area. Some multi part designs add a spacer or locking element to increase current capacity and durability. Tight machining tolerances, quality plating, and spring selection determine friction, wear, and consistent resistance over many cycles.

How 2 pin spring connector Work

2 pin spring connector converts mechanical compression into reliable electrical contact. When a mating surface presses the two plungers, each internal spring compresses and forces the plunger against its mating pad or counterpart, creating intimate metal to metal contact. The spring ensures a defined contact force that breaks surface films and compensates for mechanical tolerances and vibration. Because each pin moves independently, the module tolerates misalignment and uneven surfaces while maintaining continuity. Upon disengagement, springs return plungers to rest position. This simple mechanical principle yields low, repeatable contact resistance and long cycle life when materials and plating are properly specified.

2 pin pogo connectors contact resistance

Contact resistance is a key specification for pogo connectors and depends on contact metallurgy, plating, contact geometry, and spring force. Gold plating over nickel or similar underplates is commonly used to minimize oxidation and maintain stable resistance. Typical production values are engineered to be low (often tens of milliohms or better per contact under specified test force), but exact figures vary by product and current rating; many small SMD or DIP pins list 10–30 mΩ max as a guideline. Higher contact force and larger contact geometries reduce resistance, while poor plating or contamination increases it so Kelvin (four wire) testing under load is recommended for verification.
