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-Barrel-Spring-housing

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

Excellent Mechanical Features

🧩 Board-to-Board Connections
The board-to-board (B2B) pogo pin ensures seamless communication in space-constrained internal circuit boards, eliminating wiring. They are an affordable, space-saving solution, often ideal for applications with lower demands on plug-and-unplug cycles.

🔧 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.

⚡ 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.
🔄 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.

⚙️ Electrical Stability

303 series pogo pins, with a current rating range of 1 to 3 amps, are specifically designed to address mechanical stress, temperature fluctuations, and frequent mating cycles. This enables consistent electrical performance over an extended lifespan, making them ideal for a wide range of applications.

📏 Tiny Size for Confined Space
Our pogo pins are compact and lightweight, and their basic working heights are 2.6~6.8mm, whereas the diameter of a single pogo pin is 1.80~1.83. 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.

Mounting Types of Pogo Pin

Mounting Types of Pogo Pin
Pogo pins come in various mounting configurations to suit different assembly needs, common mounting types include: SMT/SMD, Through Hole, Double-Ended, High Current, Right Angle, Bending Type, Solder Cup, Thread Screw, DIP Mounting. ATTEND currently offers SMT pogo pins, through-hole mounting pogo pins and DIP pogo pins, catering to multiple applications.

SMT (Surface Mount Technology)

These pogo pins are soldered directly onto the PCB surface, and offer a compact, space-saving design, which is suited for modern, miniaturized electronics. Plus, SMT facilitates faster and more automated assembly processes, leading to quicker production times.

Through-Hole Mounting

Through-hole pogo pins have leads that pass through holes in the PCB and are soldered on the other side. This method provides a robust mechanical connection, ideal for applications requiring high durability and resistance to shock or vibration.

DIP (Dual In-Line Package)

DIP pogo pins have plug-in mechanisms, allowing them to be easily placed onto the PCB by hand before being soldered in place. It's also easier to inspect and rework compared to through-hole mounting, making it suitable for on-site maintenance. Though this mounting method is no longer common in modern devices, they are still highly compatible across multiple vendors.

How to Select the Right Pogo Pin Manufacturers

While cost is an important consideration in choosing the right manufacturers, it shouldn't be the sole deciding factor, as pogo pins are critical components and their quality directly impacts your device's functionality and longevity. 

So, be sure to look for a manufacturer that provides competitive pricing, with a proven track record of producing high-quality, durable pogo pins, while also offering a variety of pogo pin options, including different sizes, pin amounts, and spring forces, that cater to your specific needs. 

Moreover, you should ensure the manufacturer has the capacity to meet your production volume requirements and deliver your order on time.
