Spring Loaded Pogo Pins & Connectors

What are Pogo Pins?

Pogo pins, contact pins, or spring-loaded connectors, are key for creating temporary yet reliable electrical connections in various electronic devices. What sets them apart from other common PCB connectors is their spring mechanism, which ensures consistent contact by applying a constant force. The spring design also allows them to flex and maintain a stable connection, even if there are slight misalignments during assembly. Furthermore, pogo pins often require less board space compared to bulkier connectors, simplifying PCB layout while potentially reducing overall device size. This makes them indispensable in applications like charging ports, data transfer interfaces, and testing environments.

The widespread adoption of pogo pins began in the mid-20th century, alongside the miniaturization of electronic components, as their design proved perfect for ensuring reliable connections in increasingly compact devices, replacing the older low-current pin models that were unstable and extremely sensitive to vibration.

At ATTEND, we offer a comprehensive range of pogo pin types to satisfy your specific needs, from standard and magnetic options for robust applications, to waterproof variants for demanding environments. We also specialize in multi-pin connectors that efficiently handle complex circuitry, and single pin designs that provide focused connectivity for specialized tasks.

Pogo Pin Components

A pogo pin usually consists of 3 to 4 components, including the barrel, the spring, the pin and the optional housing, which all work in perfect sync to help provide connectivity.

Barrel

The barrel acts as a sturdy outer casing which provides structural support and protects the delicate internal components from external impact. It also guides the movement of the pin, by keeping it centered and preventing excessive lateral movement.

Spring

The spring is the heart of the pogo pin's functionality, it is typically a coiled conductive metal structure that will create a constant pressure, to ensure that the pin maintains a firm connection with the mating surface, even with slight variations in alignment. The spring can also be compressed and extended, which allows the pogo pin to absorb some shock or vibration, thus preventing accidental disconnections.

Pin (Plunger)

The Pin or plunger is the conductive tip of the pogo pin that is lodged directly above the spring coil, allowing it to retract and touch the barrel when external force is applied. When the plunger comes into contact with an electric current, it will transmit the current to the other end, to facilitate the electrical flow within the pogo pin. The size of the contact area formed when the plunger touches another conductor also plays a crucial role. The larger this contact area, the lower the resistance to electrical current flow.

Housing

Additionally, a housing component can be used to neatly encase and organize multiple pogo pins, to create a multi-pin connector. It ensures proper spacing between individual pins and provides a secure, unified structure for connecting to the PCB or mating surface, which is necessary to accommodate multiple connections simultaneously in complex circuitry.

Quality Material

Pin (Plunger): Made from brass coated with gold or nickel for durability, corrosion resistance, hardness and excellent conductivity.
Spring: Made from stainless steel as the material has strong resilience to ensure a consistent spring force over extended use. It also boasts resistance towards corrosion and high temperatures, while having non-magnetic properties to ensure smooth operation.
Barrel: Commonly made from brass or phosphor bronze. Brass is a cost-effective option that is also valued for its good formability, which allows the creation of various barrel shapes; phosphor bronze, though more costly, offers a good balance of conductivity and formability, while providing superior corrosion resistance compared to brass.
Housing: Made from Thermoplastic LCP (Liquid Crystal Polymer) PA6T that can withstand higher temperatures and many types of chemical, allowing it to maintain its shape under varying harsh conditions and mechanical stress better than traditional thermoplastics. This housing material also offers good insulating properties to prevent electrical shorts and ensure safe operation.

Excellent Mechanical Features

🔧 Broad Spring Force Ranges
A proper spring force guarantees stable electrical connection between the pin and the mating surface, accommodates misalignment, and enhances shock resistance, vital for reliable device operation and longevity. At ATTEND, we offer a wide range of spring forces beyond the standard 0.5N - 1.5N range. This allows us to tailor our pogo pins to your specific application needs, to ensure optimal contact pressure for maximum performance and reliability.

🔩 Great Pin Strength
We utilize sophisticated CNC machining techniques, combined with quality material and high-precision design to create strong and durable pins. Additionally, for your special needs, we perform simulation analysis to provide the most suitable spring plungers.

🔄 High Mating Cycles
With a range of 10,000 to 50,000 mating cycles, our pins offer an impressive lifespan. This reduces the need for frequent replacements and ensures devices remain functional over extended periods.

⚡ Low Contact Resistance
Contact resistance between the pogo pin and the mating surface is influenced by factors such as material selection, contact force, and surface finish. ATTEND minimizes contact resistance to 20mΩ, not only by providing a proper spring force to maintain a firm connection, but also by selecting high-conductivity materials like brass with gold-plating for the pin, and creating a smooth and clean contact surface to ensure reliable signal transmission.

⚙️ Electrical Stability

This makes them ideal for applications in limited spaces, from miniature portable electronics to wearable devices. They are sleeker alternatives to traditional connectors like USB, HDMI cables, and audio cables which are bulkier.

🌡️ Harsh Environment Tolerance
ATTEND select highly-resistant materials such as stainless steel and phosphor bronze to provide great tolerance against moisture and other corrosive elements. A protective gold plating is also used to further enhance corrosion resistance and improve overall durability. Our pogo pins can also withstand an operating and storage temperature range of -40°C to +85°C, allowing them to provide reliable connections while preventing expansions, contractions or any other material deformation, even when exposed to extreme conditions.
