Dip Pogo Pins
Spring Loaded Double Ended Pin Catalog

Double ended pogo pin, also known as spring-loaded double headed pins, double ended spring contacts, or through-hole spring-loaded double ended pins, are primarily used to establish reliable electrical or signal connections between components. They ensure consistent conductivity and stable contact performance in various electronic applications.

Double Ended Pogo Pins Overview

Double Ended Pogopin Product Details

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

What is a double ended pogo pin

Double ended pogo pin is a type of spring loaded electrical contact that has conductive tips on both ends instead of just one. Inside the pogo pin body, there is a small spring that allows the pin to compress and extend, ensuring reliable electrical contact even when there are small variations in distance, alignment, or vibration.

Unlike a single ended pogo pin, which typically contacts a printed circuit board (PCB) on one side and is fixed on the other, a double-ended pogo pin can connect two separate conductive surfaces at the same time. This makes it especially useful in applications where temporary, removable, or floating connections are needed.

Double ended pogo pins are commonly used in test fixtures, battery contacts, board-to-board connections, charging docks, and modular electronic assemblies. They allow fast assembly and disassembly without soldering, reducing wear on connectors and improving maintenance efficiency.

How to install double ended pogo pin

Fixed Installation in a Plastic Housing (Press-Fit)
Press the double ended pogo pins firmly into the inner hole of the plastic housing to secure them in place. No soldering is required. Ensure that both plungers are compressed to the working height specified in the drawing. Once properly compressed, the pogo pins will operate reliably.

Floating Installation in a Plastic Housing (Suspended Type)
Insert the double ended spring loaded contacts into the pre-designed inner hole of the plastic housing without rigid fixing. Make sure the pins are compressed to the working height specified in the drawing to ensure normal operation. This installation method is also ideal for test fixtures and electronic component testing applications.

double ended pogo pin material and structure

Double ended pogopin material & Parts

Double ended pogo pin features two movable plungers at both ends, a central barrel, and an internal spring. The plungers are typically made of brass or phosphor bronze for excellent conductivity and mechanical strength, with nickel and gold plating to reduce contact resistance and improve corrosion resistance. The barrel is usually made of brass or stainless steel with similar surface treatment, while the internal spring is made from stainless steel or music wire to ensure stable elasticity and long service life. When insulation is required, high-temperature engineering plastics such as PEEK or LCP may be used. Its key advantages include compact design, easy and fast installation, and the ability to be fixed or float within the inner hole of a plastic housing, allowing reliable operation even with assembly tolerances.

double ending pogopin internal structures

Double Ended Pogopin Internal Structures

Double ended pogo pins are designed with compact and reliable internal contact mechanisms. The commonly used internal structure of the contact double ended pin is the plunger bevel structure. In this design, a movable plunger operates inside a hollow barrel, guided by a beveled interface that ensures smooth alignment and stable contact. An internal spring applies consistent pressure from both ends, enabling reliable electrical connection. The components are typically gold plated to reduce contact resistance and prevent corrosion. Alternative internal structures exist, but the plunger bevel structure is preferred for its durability, stability, and long service life in high cycle applications.

How Double Ended Pogo Pins Work

Double ended pogo pins operate through the coordinated action of an internal spring, bevel structure, plunger, and barrel to provide stable and reliable electrical connections. When pressure is applied from either end, the spring compresses and the bevel converts lateral force into vertical contact force, allowing the gold-plated plunger to press firmly and continuously against the inner wall of the barrel. This ensures consistent contact, while the gold plating reduces oxidation and minimizes contact resistance for long-term reliability. The design achieves extremely low and stable contact resistance even under vibration, shock, or slight misalignment. With a double-ended structure, pogo pins efficiently transmit signals or power between opposing pads, making them ideal for test fixtures, board-to-board connections, and modular systems.

Dip Pogo Pin Contact Resistance

This chart illustrates that during the full compression and release stroke of the dip pogo pin, the spring force increases smoothly while the contact resistance remains extremely low and stable. This demonstrates a well-engineered internal structure, precise machining tolerances, and high-quality vacuum blind-hole plating that together ensure reliable electrical connectivity and long-term performance stability.
